Use "int main(void)" instead of just "int main()" so that compiling with
"gcc -Werror=strict-prototypes" works. Test this check using the flags
"-Werror -Wstrict-prototypes" to work with old GCC versions.
A cycle exists when the DFS returns to the root node, not just when
multiple paths lead to the same node.

Evaluate in the COMMAND arguments of custom commands the generator
expression syntax introduced in commit d2e1f2b4 (Introduce "generator
expressions" to add_test, 2009-08-11). These expressions have a syntax
like $<TARGET_FILE:mytarget> and are evaluated during build system
generation. This syntax allows per-configuration target output files to
be referenced in custom command lines.
Put the source files, build rules, and test scripts for these targets
under Tests/PerConfig and refer to it from Tests/Testing as a
subdirectory. The targets and scripts will be useful in other tests.
Previously the OUTPUT arguments of add_custom_command were not
slash-normalized but those of add_library and add_executable were.
This caused the example
add_custom_command(OUTPUT a//b.c ...)
add_library(... a//b.c ...)
to fail at build time with "no rule to make a/b.c". Fix this and modify
the CustomCommand test to try it.
The NAG Fortran compiler implicitly passes object files by full path to
the linker. Teach CMakeParseImplicitLinkInfo to parse object files that
match some tool-specific regular expression.
A custom command may name a target created by add_custom_target in its
DEPENDS field. Treat this case as a target-level dependency only since
a custom target provides no standard file on which to add a file-level
dependency.
Imported targets do not themselves build, but we can follow dependencies
through them to find real targets. This allows imported targets to
depend on custom targets that provide the underlying files at build
time.

Apple released an update recently in which there
was a broken symlink for jni.h that pointed to
a non-existent file. CMake had trouble configuring
because it encountered an error trying to read
jni.h.
We avoid the problem here by introducing a variable
CTEST_RUN_Java, which defaults to OFF on Macs, that
indicates whether to even attempt finding java, reading
jni.h and adding the "Java" CMake test.
If you would like to test Java on a Mac where the
jni.h symlink is not busted, feel free to pass in
-DCTEST_RUN_Java:BOOL=ON when configuring CMake.
IF(... MATCHES ...) used for comparing directories chokes especially in the case of C:\Program Files (x86)\<blah> because of regex pattern matching. Switched this to use STREQUAL in a loop instead.
Use a longer value as the default timeout (6 hours).
For a per-contract-test timeout value, set ${project}_TEST_TIMEOUT
in the project's RunTest.cmake file. To use a longer value for
all non-specific contract tests, set a CMake cache variable
named CMAKE_CONTRACT_TEST_TIMEOUT_DEFAULT.
All timeout values are in seconds.
Also, patch up last commit to defer evaluation of ENV{HOME}
until EnforceConfig.cmake is included at ctest time. This
allows Windows machines to have "\\" characters in the HOME
environment variable if they want to.
To activate the CSE contract test on a given Linux
machine's CMake dashboard, put
CMAKE_CONTRACT_PROJECTS:STRING=cse-snapshot
in the CMake dashboard's initial cache.
The chosen snapshot does not generate subproject
dependency info right now. That code was in a
previous revision in the CSE's svn repo that
apparently has not been merged into the present cse
git repository master branch. After that is fixed up
in the cse repo, we can update the tag here so that
the snapshot built here can run a sub-project based
dashboard script. For now, it runs as one big build
step, building 'all'.

220c5dc Add test that CMake errors with empty libs
Visual Studio Express editions do not support solution folders,
so default behavior should be as if USE_FOLDERS global property
is OFF.
Also, allow folder names to be the same as target names: internally,
use a prefix to distinguish folder GUIDs from target GUIDs. Add
a target and folder with the same name in the ExternalProject
test to exercise this code.
For CMake itself, provide a new option CMAKE_USE_FOLDERS that
defaults to ON so that Visual Studio users get a nicely organized
CMake project. Express edition users will have to turn off the
CMAKE_USE_FOLDERS option in order to build CMake in the VS Express
IDE.
Some HPUX compilers give this error: Error 690: "/home/cport/Dashboards/My Tests/CMake-build/Tests/CheckCompilerRelatedVariables/main.cxx", line 1 # Nonempty source files must end with a newline that is not preceded by a backslash.

The idea is that we can make sure that CMake is staying backwards
compatible by testing projects against CMake as the changes are made
in CMake. Because these tests will take a long time to run, they
will not be enabled by default. Instead, they will be enabled by
putting a cache variable into CMake.
Test still failing on dash1.kitware. Give up on testing
the new arg on MSVC71. Test it with newer nmakes instead.
All other dashboards are fine with -DPATH=c:/posix/path
as the first arg, so keep it except when MSVC71 is true.

ed37fc3 VS2010: Set IntDir for utility and global targets.
e79e412 VS2010: Honor PROJECT_LABEL target property (#10611)
530ade6 Fix targets with . in the name for VS 10 IDE.
The new first arg in the test is the critical one
to prove that the new NMake specific code works.
The additional colons in the middle of the arg
stream work fine everywhere else, but not on
dash1.kitware with Visual Studio 7.1. Just avoid
the failure for now by removing the unnecessary
new args from the test.
The nightly dashboard showed that the following
platforms had difficulties dealing with "bin dir"
and/or "check command line" as directory and
file names:
AIX
Borland 5.5, 5.6 and 5.8
IRIX
NMake 6.0
OpenBSD
VS 7.1
Watcom
Re-visit later, after the release, to use spaces
in the bin dir and in the target name where possible.
The solution seems hackish, but it works: for
NMake only, prepend a no-op command before each
real command that begins with ".
This is really a work-around for an NMake problem.
When a command begins with ", nmake truncates the
first argument to the command after the first :
in that arg. It has a parsing problem.
Workaround..., hackish..., but it should solve
the issue for #9963 and its related friends.
Also, modify the CustomCommand test to replicate
the problem reported in issue #9963. Before the
NMake specific code change, the test failed.
Now, it passes. Ahhhhhh.

See the newly added documentation of the FOLDER target
property for details.
Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.
By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.
This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.
Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.
This command allows a user to quickly see the list of all available
test labels. The labels are also printed in verbose show only mode,
alongside their corresponding tests.
Strong dependencies (created by add_dependencies) must be honored when
linearizing a strongly-connected component of the target dependency
graph. The initial graph edges have strong/weak labels and can contain
cycles that do not consist exclusively of strong edges. The final graph
never contains cycles so all edges can be strong.
This commit introduces the ability to add custom targets
that correspond to individual ExternalProject steps.
The main motivation behind this new feature is to drive
sub-project based dashboard steps as external projects
with separate targets for update, configure, build and
test output. This makes it easy to construct a ctest -S
script to drive such a dashboard.
With no STEP_TARGETS defined, there are no additional
custom targets introduced, to minimize the chatter in
the target name space. Clients may define STEP_TARGETS
on a per-ExternalProject_Add basis, or at the directory
level by setting the EP_STEP_TARGETS directory property.
When a module is first contributed Kitware has made no modifications on
which to place a copyright. Require the contributor to have a copyright
notice, but not specifically by Kitware.
Add platform configuration variable CMAKE_SYSTEM_IGNORE_PATH and user
configuration variable CMAKE_IGNORE_PATH. These specify a set of
directories that will be ignored by all the find commands. Update
FindPackageTest so that several cases will fail without a functioning

If GIT_EXECUTABLE is not passed in, and is not available from
DartConfiguration.tcl or CTestConfiguration.ini, then make one
more last ditch attempt to get it from Update.xml, if there is
an Update.xml. For dashboards that have successfully done a
ctest_update call, there should be an Update.xml in the Testing
subdir of the binary tree. Parse that file for the git executable
recorded in the <UpdateCommand> element.
And make this test pass on those RogueResearch dashboard machines!
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines. Instead the
message body is terminated by '\0' and there is no diff section. Teach
CTest to parse the format in this case.
If GIT_EXECUTABLE is not passed into the test, but the source
tree is a git checkout, then use GitCommand or UpdateCommand
from the ctest ini file to set its value. Presumably, a dashboard
running the test suite had to have set this properly in order
to do the ctest_update step.
Optionally hide the output of each external project build step by
wrapping its command in a launcher script. Make output available in log
files instead. This simplifies the output of external project builds.
At this point, CTestTest3 causes more problems than it's worth.
It uses CVS to grab a remote (over the network) copy of kwsys
code for testing. This causes some sort of problem nearly every
night on the nightly CMake dashboards. Worse: it causes problems
on different machines on different nights, then the next day, it's
fine again. So: remove this test and monitor the coverage.
If we lose a significant portion of code coverage, I will revert
this commit and re-activate the test. However, if we do not lose
a significant portion of code coverage, I will remove the code
for the test as well as removing it from the CMakeLists.txt file.
Brad King and I discussed this over the last few weeks, and we both
think we have sufficient coverage of all the checkout and update code
in other locally (non-network) based tests.
On the other hand, even if we do take a mild hit on coverage temporarily,
it should be relatively easy to increase our coverage again by adding
bits to those other locally based tests.
The bootstrap script works under MSYS, so test it. Use a launcher batch
file since 'ctest --build-and-test' is a Windows program and will not
honor the shebang line in the script.
Even though this test is checking that the ctest running it can handle
test output without newlines we should run the just-built CMake binary.
This allows the MemCheck test mode to check the correct CMake.
Use 'git fetch' followed by 'git reset' to update the source tree. This
is better than 'git pull' because it can handle a rewritten upstream
branch and does not leave local modifications. After fetch, parse
FETCH_HEAD to find the merge head that 'git pull' would choose to track
the upstream branch. Then reset to the selected head.
In the normal fast-forward case the behavior remains unchanged.
However, now local modifications and commits will be erased, and
upstream rewrites are handled smoothly. This ensures that the upstream
branch is tested as expected.
Teach (create|run)_dashboard_script macros to treat the argument as the
name of a build tree. Append '.cmake' to generate the dashboard script
name. This allows future re-use of the macros for multiple test
scripts.
Use it from ExternalProject and the ExternalProject test's
CMakeLists file rather than having duplicate find_program calls.
Add logic so that we do not try to use *.cmd variants of git
programs when using the MSYS Makefiles generator. Should fix
the last remaining dashboard issue with the new ExternalProject
git support additions.
Also, correct minor problem regarding placement of the local git
repo during test execution. On clean builds, it was being placed
incorrectly because of the ../.. relative reference. Use an absolute
path to place the local git repo in the proper directory, and only
use the relative reference when referring to it.
The Intel C compiler for Linux does not seem to reject any bad flags or
object files on its link lines. Work around the problem by using a
preprocessor #error directive to ensure that BADFLAG appears in the
build output. This does not really achieve the purpose of the tests but
it allows them to pass.
Double quote executable names that may have spaces in them.
Do not run the new git portions of the test on machines that
have git < version 1.6.5 on them.
The Borland librarian actually creates a BADFLAG.obj when the object is
missing the first time! This causes later tests to not reject it.
Instead use a Borland-specific variation on the flag.
Add archives of these file types and add to the test
cases covered in the ExternalProject test.
Also add an "Example" directory in the Tests/ExternalProject
directory containing the canonical simplest example of
ExternalProject usage.
Add a LinkFlags test series to check that these properties work. Since
no link flag is accepted everywhere we test for presence of flags by
adding a bad flag and looking for the complaint in the test output.
Echo results of calling git status before exiting with
an error. Add one special case so that the test may pass
on the dashmacmini2 continuous dashboard, despite a 'git
status' non-zero return code. More logic like this may
be required. I will re-evaluate based on tomorrow's
nightly dashboard runs.
Additionally, output some more information in both cvs
and git cases. When it is a cvs checkout, echo the contents
of CVS/Root and CVS/Repository to the test output. When it
is a git checkout, echo the output of 'git branch -a'.
This will allow us to see more details about any given CMake
source tree right in the CDash results for this test.
Improve FILE(DOWNLOAD ...):
- Add percent complete progress output to the FILE DOWNLOAD
command. This progress output is off by default to
preserve existing behavior. To turn it on, pass
SHOW_PROGRESS as an argument.
- Add EXPECTED_MD5 argument. Verify that the downloaded
file has the expected md5 sum after download is complete.
- Add documentation for SHOW_PROGRESS and EXPECTED_MD5.
When the destination file exists already and has the
expected md5 sum, then do not bother re-downloading
the file. ("Short circuit" return.)
Also, add a test that checks for the status output
indicating that the short circuit behavior is actually
occurring. Use a binary file for the test so that the
md5 sum is guaranteed to be the same on all platforms
regardless of "shifting text file line ending" issues.
Improve ExternalProject:
- Add argument URL_MD5.
- Add verify step that compares md5 sum of .tar.gz file
before extracting it.
- Add md5 check to download step, too, to prevent
unnecessary downloads.
- Emit a warning message when a file is not verified.
Indicate that the file may be corrupt or that no
checksum was specified.
Add the <Email>...</Email> element in Update.xml for each commit
reported. This field was defined by Dart but never really used.
Distributed version control systems use author name and email
instead of a user id, so now it makes sense to use this field.
Some Mac linkers produce the message
"file was built for unsupported file format which is not the
architecture being linked"
for this test. Update the test output regex to match it.
Git does not automatically checkout the matching version of a submodule
when it checks out a new version of the parent project in the work tree.
If the submodule reference changed in the parent project then we were
reporting the submodule path as a local modification. Work around the
problem in ctest_update using "git submodule update" after "git pull".
For projects with no submodules this is a no-op. See issue #10662.
Also add a submodule to the test project for CTest.UpdateGIT to test the
work-around.
For builds from Git repositories, add "-g<commit>" to the end of the
version number. If the source tree is modified, append "-dirty".
For builds from CVS checkouts, add "-cvs-<branch>".
If defined and non-empty, the value of CMAKE_TESTS_CDASH_SERVER should point
to a CDash server willing to accept submissions for a project named
PublicDashboard. On machines that also run a CDash dashboard, set this
variable to "http://localhost/CDash-trunk-Testing" so that the CMake tests
that submit dashboards do not have to send those submissions over the wire.
The CTestSubmitLargeOutput test runs a dashboard that has a test that produces
very large amount of output on stdout/stderr. Since we do not even want to
attempt to send such large output over the wire, this test is off by default
unless the CMAKE_TESTS_CDASH_SERVER server is localhost. This test is expected
to cause a submission failure when sent to CDash. It passes if the submit
results contain error output. It fails if the submit succeeds.
CMAKE_TESTS_CDASH_SERVER: CDash server used by CMake/Tests.
If not defined or "", this variable defaults to the server at
http://www.cdash.org/CDash.
If set explicitly to "NOTFOUND", curl tests and ctest tests that use the
network are skipped.
If set to something starting with "http://localhost/", the CDash is expected
to be an instance of CDash used for CDash testing, pointing to a
cdash4simpletest database. In these cases, the CDash dashboards should be
run first.
Commit "Teach CTest.Update tests to strongly check entries" (2010-02-09)
started checking Update.xml entries strongly. This revealed that some
cvs clients report "U CTestConfig.cmake" during update even though the
file did not change and it selects the same revision. As a result the
test fails with
Update.xml has extra unexpected entries:
Updated{CTestConfig.cmake}
We fix the test to tolerate this particular extra entry without failing.
We wrap the git executable in a shell script that touches one source
file after 'git pull'. This makes the file newer than the index even
though it has not actually changed. If CTest does not refresh the index
properly then the test will fail with a bogus modified file.
Previously these tests just checked for matching file names in the
Update.xml files. Now we check the update types (Updated, Modified, or
Conflicting) and reject unexpected extra entries.
At least one Fortran compiler does not provide a preprocessor symbol to
identify itself. Instead we try running unknown compilers with version
query flags known for each vendor and look for known output. Future
commits will add vendor-specific flags/output table entries.
The PathScale compiler silently accepts unknown options that start in
more than one '-':
$ touch foo.c
$ pathcc -c foo.c --junk
$ echo $?
0
$ pathcc -c foo.c ---junk
$ echo $?
0
$ pathcc -c foo.c -junk
pathcc ERROR parsing -junk: unknown flag
$ echo $?
2
We teach the TryCompile to pass a bogus flag with only one '-' instead
of three '-'s for this compiler.
We disable this test because PathScale Fortran mangles module symbols as
"MYSUB.in.MYMODULE" so we cannot interface with it from C. We already
did this for SunPro and MIPSpro.
Makefile dependencies must be escaped using cmLocalGenerator::Convert
with the cmLocalGenerator::MAKEFILE option. This fixes Fortran module
dependencies with spaces in the path. We test the fix by adding a space
to one of the module paths in the Fortran test.
If APPEND is given to ctest_start, it will read the tag from the current existing Testing/TAG file rather than creating a new one based on the current time stamp. This allows a developer to run several dashboard scripts in a row, all of which will share the same tag/stamp/buildid when they finally get submitted to CDash. Now you can split the running of build phases and test phases for the same dashboard row into multiple scripts.
The commit "Make CTestTestTimeout time configurable" added a CMake cache
variable CTestTestTimeout_TIME to configure the length of the timeout
used by the inner CTestTestTimeout test. The reason was to allow users
on slow machines to give this test some extra time without extending the
timeout for everyone. However, Cygwin CMake seems to load slowly enough
that it is worth a longer default timeout for that platform.
The commit "Submit Subversion directory path in Update.xml" added the
element <SVNPath>...</SVNPath> to Update.xml for Subversion work trees.
This commit teaches the CTest.UpdateSVN test to verify the presence of
the element.
We teach CTest to report in a <Revision> element the revision of the
source tree that was tested. This makes sense for all modern VCS tools
because they version the whole tree. We simply omit this element for
CVS because it only versions files. See issue #7541.
We teach ADD_TEST_MACRO to transform names of the form "Namespace.Name"
to the directory "Namespace/Name" and the project name "Name". This
will allow new tests to be better organized.
The test overrides the CMAKE_C_FLAGS and CMAKE_Fortran_FLAGS to test
passing a specific flag to the compiler wrapper scripts. We fix it to
honor any outside flags needed for the real compiler.
The commit "FortranCInterface: Honor language flags in checks" taught
the FortranCInterface module to pass C and Fortran flags into its
detection and verification checks. We improve on the change to allow
the '=' character in the language flags. This requires passing the
cache entry type with the -D options.
We create test FortranC.Flags to try passing per-language flags from a
project into its FortranCInterface detect/verify checks. We wrap the
compilers with scripts that enforce presence of expected flags.
CMake does not enable Fortran for its own build, but it needs to find a
Fortran compiler to know if it is possible to enable Fortran tests.
Previously we searched for a hard-coded list of Fortran compilers which
was duplicated from the CMakeDetermineFortranCompiler.cmake module. We
now run CMake on a small test project that enables the Fortran language
and reports the compiler it found. This represents a more realistic
check of whether the Fortran tests will be able to find a compiler.
Previously our EnforceConfig script that loads at test-time would only
enforce a non-empty CTEST_CONFIGURATION_TYPE for CMake 2.6.2 and lower.
Now we simply always enforce use of a configuration, and select one of
the configurations that was built if none is given.
This is necessary to run tests like CMake.Install that need to know the
configuration with which CMake was built.
We create option CMake_TEST_INSTALL to enable a new CMake.Install test.
It tests running the "make install" target to install CMake itself into
a test directory. We enable the option by default for dashboard builds.
We configure an EnforceConfig.cmake script to load at CTest time.
Previously we loaded it from Tests/CTestTestfile.cmake, but now we load
it from the top level so it applies to all tests.
Xcode 2.x forgets to create the target output directory before linking
the individual architecture pieces of a universal binary for the target
CMakeLibTests. Then it passes the directory to -L and -F options when
linking the and warns that the directory does not exist. We work around
the problem by using a pre-build rule on the target to create the output
directory.
We re-arrange EXECUTABLE_OUTPUT_PATH settings to avoid putting utility
and test executables in the 'bin' directory of the build tree. This
makes the directory look like that in the installation tree, except that
on multi-configuration generators we still use a per-config
subdirectory.
The DumpDocumentation executable and some supporting code and tests were
completely unused by CMake. Generation of documentation is done by the
individual executables with --help* options. In this commit we simply
remove the unused code, executable, and test.
In this test we start up a cmake script that runs a process that sleeps,
and the timeout for the script is shorter than the sleep time. However,
in order to properly detect that the sleeping grandchild is killed when
the script times out we need to give sufficient time for the script to
start the grandchild. Otherwise the log file for the grandchild is not
available.
On some (cygwin) builds our previous 1 second timeout for the script was
not long enough to let the interpreter load and start the grandchild.
We make the timeout time configurable by setting CTestTestTimeout_TIME
in the cache for CMake itself. It tells the test how long to let the
script run. The grandchild always sleeps for 4 seconds longer to ensure
a comfortable window during which the process tree can be killed.
This test requires that the dashboard script it drives be invoked with
"ctest -C <config> -S ...". We create a "CTestTest_CONFIG" variable to
hold a configuration selected at test time. We use the configuration
given to the outer CTest, if any, and then default to either Debug or
the CMAKE_BUILD_TYPE.
We extend the CTestTestTimeout test to check that when a test times out
its children (grandchildren of ctest) are killed. Instead of running
the timeout executable directly, we run it through a cmake script that
redirects the timeout executable output to a file. A second test later
runs and verifies that the timeout executable was unable to complete and
write data to the log file. Only if the first inner test times out and
the second inner test passes (log is empty) does the CTestTestTimeout
test pass.
The commit "Fake $HOME to isolate tests from user" started setting $HOME
in the CTest script environment. On some platforms tests depend on some
local configuration in the home directory, such as the "cvs login" for
KWSys in CTestTest3.
In this commit we now construct a fake home dir during CMake config step
and populate it with a .cvspass file needed by the test. We also check
CTEST_NO_TEST_HOME to optionally disable the test home.
See issue #9949.
On platforms with $HOME in the environment, some of our features use it
to store information in the user home directory. However, tests for
these features should not touch the real user home directory. Instead
we configure a fake $HOME that points inside the build tree for use
during testing.
See issue #9949.
The commit "Fix get_filename_component ABSOLUTE mode" broke REALPATH
treatment of relative paths because it stopped storing the absolute path
in local variable 'filename'. This commit fixes the call to GetRealPath
to use the proper local variable and adds a test.
Some compilers use implicit link options of the form
-lcrt*.o
-lgcc*
-lSystem (on Mac)
-lSystemStubs (on Mac)
that provide system-wide symbols not specific to any language.
These need not be listed explicitly for mixed-language linking.
We teach CMake to remove the above items from the implicit library list
of each language. This change makes it possible to mix GNU compiler
versions in some cases.
This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers. The cmake -E tar xf should be
able to handle all compression types now as well.
The commit "Test per-config OUTPUT_DIRECTORY properties" added this test
with a find_library() call in a CMake script, which requires an explicit
list of possible library prefixes and suffixes. This commit adds more
suffixes to match the libraries built on HP, MinGW, and Cygwin.
We test (ARCHIVE|LIBRARY|RUNTIME)_OUTPUT_DIRECTORY_<CONFIG> properties
by building COnly as a subdirectory and setting the properties to put
its files in specific locations. We build an executable that verifies
the targets actually appear where expected.
The BuildDepends test exercises incremental linking with MSVC and Intel
tools on Windows. In some cases the Intel compiler creates objects that
cause the MS linker it invokes to crash during incremental linking. We
avoid the problem for this test by disabling incremental linking.
We introduce the "CMake.If" test to try out conversion of constants and
variables to boolean values in the if() command. We cover both OLD and
NEW behavior for policy CMP0012.
The commit "Test all target types in Fortran" enabled a SHARED library
in the Fortran test. However, we do not yet implement support for
shared libraries with XL Fortran (it seems this requires using the C
compiler to link). Furthermore, the old g77 2.97 from Red Hat does not
support shared libs on Itanium because the g2c lib is not -fPIC.
For now we just disable SHARED libs in the test for these tools.
We add Intel and MinGW Fortran linker options to create the import
library portion of a DLL. This allows other binaries to link to a
Fortran DLL.
We also update the Fortran test to use a .def file to specify exports
since there is no __declspec(dllexport) markup syntax in Fortran.
To enable this test, the option TEST_KDE4_STABLE_BRANCH must be switched on.
It can only be switched on if CMAKE_RUN_LONG_TESTS is ON.
Then the test will only be added if Qt >= 4.5 can be found, Perl can be
found and ZLIB can be found.

This commit re-writes Borland compiler build rules. We split the rules
into modern <os>-<id>-<lang> information modules but share a common
macro between languages to avoid duplication.
We also address a bug in the previous rules that would build some target
types against the static Borland runtime and others against the shared
Borland runtime in one build tree. Now we always use the shared runtime
as is the default in the rules for MS tools.
Previously we passed inputs to the decision to each Complex test and let
the test source decide. This commit moves the decision out of the tests
and makes it an option() in their source. This makes it possible to
build the Complex tests from outside the CMake test tree.
When <pkg>_DIR is set to an incorrect version we search again and store
the result in the variable, even if it is <pkg>_DIR-NOTFOUND.
There was a bug in the case when the new search does not find anything
and the old value came from a cache entry with UNINITALIZED type. The
command used to try to load a package configuration file from the last
place searched, and would leave the old wrong value in the entry. This
commit fixes the behavior to avoid trying to load a missing file and to
set the value to <pkg>_DIR-NOTFOUND as expected.
The regex used by CMAKE_PARSE_IMPLICIT_LINK_INFO to detect link lines
should not match lines that happen to have ".../ld.../..." in them. A
linker name should match only as the last component of a path.
See issue #9666.
This commit teaches the CMAKE_PARSE_IMPLICIT_LINK_INFO function to log
its actions. We store the log in CMakeFiles/CMakeOutput.log at the top
of the project build tree. This will make diagnosis of implicit link
information parsing problems easier.
In the Fortran test we use a custom command to build another Fortran
project internally. The project provides a Fortran module and library
to which to link. This commit teaches the test to build the extra
project using the same build configuration as the main project.
We need to leave out the '%' character from tests with the Intel
compiler. Since '%' needs to be written '%%' in NMake when not using a
response file but just '%' when using a response file, we just skip the
character for now. It works with MSVC in NMake only because that
compiler expects '%%' inside response files, which do get used.
CMake defines MSVC only for a VS compiler, but the Intel compiler adds
the preprocessor definition _MSC_VER. Instead of relying on separate
tests to decide whether to use example_dll_2, we do one test in CMake
and then add our own preprocessor definition.
We test this by adding export(TARGETS) to the LinkLanguage test to
export the executable before the library is linked to it. Since
export(TARGETS) computes the link interface of the target (so that it
can export it), this ensures that the information is recomputed after
the link library is added.
This adds a "ModuleDefinition" test enabled when using MSVC tools. It
checks that .def files can be used to export .dll and .exe symbols and
create corresponding .lib files that can be linked. See issue #9613.
Policy CMP0002's OLD behavior allows duplicate non-custom targets. We
test it with a project that builds two executables of the same name by
setting CMP0002 to OLD.
The flag "-_this_is_not_a_flag_" was not rejected by GCC 4.0 on older
Mac OS X. We now use "---_this_is_not_a_flag_" instead, which will
hopefully be rejected by all compilers.
The CMake.File test runs several scripts through "cmake -P" and checks
the output and result against known good values. This commit factors
out the checking code into a separate CMakeCheckTest module. The module
may be used by new tests.
This commit teaches the FunctionTest to check variable scope behavior
when a subdirectory is added inside a function call. Any PARENT_SCOPE
sets in the subdirectory should affect only the function scope which
called add_subdirectory and not its parent scope.
CMake now looks for a Fortran compiler matching any C or C++ compiler
already enabled. We test this by enabling C and C++ first in the
Fortran test, which is what user projects will likely do.
Visual Studio 10 uses MSBuild to drive the build. Custom commands
appear in MSBuild files inside CustomBuild elements, which appear inside
ItemGroup elements. The Outputs and AdditionalInputs elements of each
CustomBuild element are evaluated according to timestamps on disk.
MSBuild does not use inputs/outputs to order CustomBuild steps within a
single ItemGroup or across multiple ItemGroup elements. Instead we must
put only unrelated CustomBuild elements in a single ItemGroup and order
the item groups from top to bottom using a topological order of the
custom command dependency graph.
This fixes CustomCommand and ExternalProject test failures, so we remove
the expectation of these failures.
Part of this test does "git pull" on a dirty work tree. We need to make
sure that 'branch.master.rebase' is false for the test repository.
Otherwise if it is true in the user configuration then pull will refuse
to rebase and the test will fail.
We teach the FindPackageTest to build a sample project that stores its
build tree in the user package registry using export(PACKAGE), and then
find it with find_package.
We test that LINK_INTERFACE_MULTIPLICITY propagates through export() and
install(EXPORT) into dependent projects. A simple cycle of two archives
that need to be scanned three times ensures that the importing project
uses the multiplicity correctly.
This function builds a simple test project using a combination of
Fortran and C (and optionally C++) to verify that the compilers are
compatible. The idea is to help projects report very early to users
that the compilers specified cannot mix languages.
This teaches the 'testing' test to try generator expressions in
arguments to add_test(NAME). This test case mimics a common use-case of
passing executables to test driver scripts. We excercise the syntax for
per-configuration target file names.
This is a new FortranCInterface.cmake module to replace the previous
prototype. All module support files lie in a FortranCInterface
directory next to it.
This module uses a new approach to detect Fortran symbol mangling. We
build a single test project which defines symbols in a Fortran library
(one per object-file) and calls them from a Fortran executable. The
executable links to a C library which defines symbols encoding all known
manglings (one per object-file). The C library falls back to the
Fortran library for symbols it cannot provide. Therefore the executable
will always link, but prefers the C-implemented symbols when they match.
These symbols store string literals of the form INFO:symbol[<name>] so
we can parse them out of the executable.
This module also provides a simpler interface. It always detects the
mangling as soon as it is included. A single macro is provided to
generate mangling macros and optionally pre-mangled symbols.
The try_compile command builds the cmTryCompileExec executable using the
cmTryCompileExec/fast target with Makefile generators in order to save
time since dependencies are not needed. However, in project mode the
command builds an entire source tree that may have dependencies.
Therefore we can use the /fast target approach only in one-source mode.
Previously the Fortran test created a single executable containing C,
C++, and Fortran sources. This commit divides the executable into three
libraries corresponding to each language, and two executables testing
Fortran/C only and Fortran/C/C++ together. The result tests more
combinations of using the languages together, and that language
requirements propagate through linking.
When building an entire source tree with try_compile instead of just a
single source file, it is possible that the CMakeLists.txt file in the
try-compiled project invokes try_compile. This commit fixes propagation
of language-initialization results from the outer-most project into any
number of try-compile levels.
The try_compile command project mode builds an entire source tree
instead of one source file. It uses an existing CMakeLists.txt file in
the given source tree instead of generating one. This commit creates a
test for the mode in the TryCompile test.
This adds sample linker invocation lines for the Intel compiler on
Linux. In particular, this exercises the case when "ld" appears without
a full path.
The Sun Fortran compiler passes -zallextract and -zdefaultextract to the
linker so that all objects from one of its archives are included in the
link. This teaches the implicit options parser to recognize the flags.
We need to pass them explicitly on C++ link lines when Fortran code is
linked.
This extends the Fortran-to-C interface test to add a C++ source file.
The executable can only link with the C++ linker and with the proper
Fortran runtime libraries. These libraries should be detected by CMake
automatically, so this tests verifies the detection functionality.
This hack was created to help the Fortran test executables link to the
implicit C libraries added by BullsEye. Now that implicit libraries
from all languages are detected and included automatically the hack is
no longer needed.
This teaches the SystemInformation test to report the CMake log files
CMakeOutput.log and CMakeError.log from the CMake build tree and from
the SystemInformation test build tree. These logs may help diagnose
dashboard problems remotely.
This extends the Fortran/C interface test to require that the executable
link to the fortran language runtime libraries. We must verify that the
proper linker is chosen.
The commit "Avoid case change in ImplicitLinkInfo test" did not change
all of the paths to mingw, so some case change still occurs. This
changes more of them.
Since "get_filename_component(... ABSOLUTE)" retrieves the actual case
for existing paths on windows, we need to use an obscure path for mingw.
Otherwise the test can fail just because the case of the paths changes.
This tests the internal CMakeParseImplicitLinkInfo.cmake module to
ensure that implicit link information is extracted correctly. The test
contains many manually verified examples from a variety of systems.
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers. We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends. We store results in new variables called
CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
The implicit libraries can contain linker flags as well as library
names.
The command "set(... PARENT_SCOPE)" should never affect the calling
scope. This improves the Function test to check that such calls in a
subdirectory scope affect the parent but not the child.
When this test was renamed from DumpInformation to SystemInformation the
configured header that points the dump executable to the directory
containing information files was broken. No information has been dumped
by this test for 2 years! This fixes it.
The ExportImport test drives its Export and Import projects using the
same compiler and flags. This converts the ctest --build-and-test
command lines to use an initial cache file instead of passing all
settings on the command line.
We need a shorter command line to pass through VS 6 on Win98.
This approach reduces duplicate code anyway.
cmCTestScriptHandler, but have it load the new script CTestScriptMode.cmake
-> that makes it more flexible, also add a simple test that the system name
has been determined correctly
Alex
This extends the ExportImport test. The Export project creates a C++
static library and exports it. Then the Import project links the
library into a C executable. On most platforms the executable will link
only if the C++ linker is chosen correctly.
This test creates a C executable that links to a C++ static library. On
most platforms the executable will not link unless the C++ linker is
chosen correctly.
This creates cmCTestHG to drive CTest Update handling on hg-based work
trees. Currently we always update to the head of the remote tracking
branch (hg pull), so the nightly start time is ignored for Nightly
builds. A later change will address this.
See issue #7879. Patch from Emmanuel Christophe. I modified the patch
slightly for code style, to finish up some parsing details, and to fix
the test.
This creates new module ExternalProject.cmake to replace the prototype
AddExternalProject.cmake module. The interface is more refined, more
flexible, and better documented than the prototype.
This also converts the ExternalProject test to use the new module. The
old module will be removed (it was never in a CMake release) after
projects using it have been converted to the new module.
This test requires a long time on slower machines, so we need to extend
its timeout. It is an important test, so it does not fall under the
CMAKE_RUN_LONG_TESTS option. In the future we should try to shorten the
test by building simpler external projects.
The test needs to create a cvs repository with 'cvs init', but the CVSNT
client on Windows needs 'cvs init -n' to avoid administrator access.
Previously we required users to explicitly enable CTEST_TEST_UPDATE_CVS
to activate the test on Windows.
This teaches the test to use the '-n' option when necessary. Now we can
enable the test in all cases except when trying to use a cygwin cvs.exe
without cygwin paths.
If an executable marks symbols with __declspec(dllexport) then VS
creates an import library for it. However, it forgets to create the
directory that will contain the import library if it is different from
the location of the executable. We work around this VS bug by creating
a pre-build event on the executable target to make the directory.
The BZR xml output plugin can use some encodings that are not recognized
by expat, which leads to "Error parsing bzr log xml: unknown encoding".
This works around the problem by giving expat a mapping, and adds a
test. Patch from Tom Vercauteren. See issue #6857.
This creates cmCTestBZR to drive CTest Update handling on bzr-based work
trees. Currently we always update to the head of the remote tracking
branch (bzr pull), so the nightly start time is ignored for Nightly
builds. A later change will address this. Patch from Tom Vercauteren.
See issue #6857.
CMake directory removal code cannot remove content from read-only
directories (a separate bug which will be fixed). Therefore we should
not create them in the StringFileTest. This tweaks the file(COPY) call
to test not giving OWNER_WRITE to files rather than directories.
This property was left from before CMake always linked using full path
library names for targets it builds. In order to safely link with
"-lfoo" we needed to avoid having both shared and static libraries in
the build tree for targets that switch on BUILD_SHARED_LIBS. This meant
cleaning both shared and static names before creating the library, which
led to the creation of CLEAN_DIRECT_OUTPUT to disable the behavior.
Now that we always link with a full path we do not need to clean old
library names left from an alternate setting of BUILD_SHARED_LIBS. This
change removes the CLEAN_DIRECT_OUTPUT property and instead uses its
behavior always. It removes some complexity from cmTarget internally.
This creates target properties ARCHIVE_OUTPUT_NAME, LIBRARY_OUTPUT_NAME,
and RUNTIME_OUTPUT_NAME, and per-configuration equivalent properties
ARCHIVE_OUTPUT_NAME_<CONFIG>, LIBRARY_OUTPUT_NAME_<CONFIG>, and
RUNTIME_OUTPUT_NAME_<CONFIG>. They allow specification of target output
file names on a per-type, per-configuration basis. For example, a .dll
and its .lib import library may have different base names.
For consistency and to avoid ambiguity, the old <CONFIG>_OUTPUT_NAME
property is now also available as OUTPUT_NAME_<CONFIG>.
See issue #8920.
The file(INSTALL) command has long been undocumented and used only to
implement install() scripts. We now document it and provide a similar
file(COPY) signature which is useful in general-purpose scripts. It
provides the capabilities of install(DIRECTORY) and install(FILES) but
operates immediately instead of contributing to install scripts.
This extends the Preprocessor test to put spaces in the value of a
definition that is not a quoted string. In particular this tests that
VS6 supports values with spaces if they do not have '"', '$', or ';'.
See issue #8779.
Previously we rejected all preprocessor definition values containing
spaces for the VS6 IDE generator. In fact VS6 does support spaces but
not in combination with '"', '$', or ';', and only if we use the sytnax
'-DNAME="value with spaces"' instead of '-D"NAME=value with spaces"'.
Now we support all definition values that do not have one of these
invalid pairs. See issue #8779.
This creates cmCTestGIT to drive CTest Update handling on git-based work
trees. Currently we always update to the head of the remote tracking
branch (git pull), so the nightly start time is ignored for Nightly
builds. A later change will address this. See issue #6994.
The add_external_project function separates its arguments with ';'
separators, so previously no command line argument could contain one.
When specifying CMAKE_ARGS, some -D argument values may need to contain
a semicolon to form lists in the external project cache.
This adds add_external_project argument LIST_SEPARATOR to specify a list
separator string. The separator is replaced by ';' in arguments to any
command created to drive the external project. For example:
add_external_project(...
LIST_SEPARATOR ::
CMAKE_ARGS -DSOME_LIST:STRING=A::B::C
...)
passes "-DSOME_LIST:STRING=A;B;C" to CMake for the external project.
Linking to a Windows shared library (.dll) requires only its import
library (.lib). This teaches CMake to recognize SHARED IMPORTED library
targets that set only IMPORTED_IMPLIB and not IMPORTED_LOCATION.
CVS clients recognize file modifications only if a file's timestamp is
newer than its CVS/Entries line. This fixes intermittent failure of the
test on filesystems with low timestamp resolution by delaying before
creating a local modification.
This creates function 'add_external_project_step' to centralize creation
of external project steps. Users may call it to add custom steps to
external project builds.
The value of CMAKE_CURRENT_LIST_FILE is supposed to be the list file
currently being executed. Before macros were introduced this was always
the context of the argument referencing the variable.
Our original implementation of macros replaced the context of command
arguments inside the macro with that of the arguments of the calling
context. This worked recursively, but only worked when macros had at
least one argument. Furthermore, it caused parsing errors of the
arguments to report the wrong location (calling context instead of line
with error).
The commit "Improve context for errors in macros" fixed the latter bug
by keeping the lexical context of command arguments in macros. It broke
evaluation of CMAKE_CURRENT_LIST_FILE because the calling context was no
longer preserved in the argument referencing the variable. However,
since our list file processing now maintains the proper value of
CMAKE_CURRENT_LIST_FILE with dynamic scope we no longer need the context
of the argument and can just evaluate the variable normally.
The add_definitions() command and COMPILE_DEFINITIONS dir/tgt/src
properties support preprocessor definitions with values. Previously
values were not supported in the VS6 generator even though the native
tool supports them. It is only values with spaces that VS6 does not
support. This enables support and instead complains only for values
with spaces. See issue #8779.
The patch step runs parallel to the update step since it does not make
sense to have both. Configuration of the step requires specification of
a PATCH_COMMAND argument to add_external_project.
This rewrites the keyword/argument parsing and handling in the
AddExternalProject module to use arguments more literally:
- The strict keyword-value pairing is gone in favor of keywords with
arbitrary non-keyword values. This avoids requiring users to escape
spaces and quotes in command lines.
- Customized step command lines are now specified with a single
keyword <step>_COMMAND instead of putting the arguments in a
separate entry (previously called <step>_ARGS).
- Build step custom commands now use VERBATIM mode so that arguments
are correctly escaped on the command line during builds.
This creates a new mode of the foreach command which allows precise
iteration even over empty elements. This mode may be safely extended
with more keyword arguments in the future. The cost now is possibly
breaking scripts that iterate over a list of items beginning with 'IN',
but there is no other way to extend the syntax in a readable way.
This creates global property RULE_MESSAGES which can be set to disbale
per-rule progress and action reporting. On Windows, these reports may
cause a noticable delay due to the cost of starting extra processes.
This feature will allow scripted builds to avoid the cost since they do
not need detailed information anyway. This replaces the RULE_PROGRESS
property created earlier as it is more complete. See issue #8726.
This creates global property RULE_PROGRESS which can be set to disbale
per-rule progress reporting. On Windows, progress reports may cause a
noticable delay due to the cost of starting an extra process. This
feature will allow scripted builds to avoid the cost since they do not
need detailed progress anyway. See issue #8726.
This creates command mode add_test(NAME ...). This signature is
extensible with more keyword arguments later. The main purpose is to
enable automatic replacement of target names with built target file
locations. A side effect of this feature is support for tests that only
run under specific configurations.
This adds the CACHE option to set_property and get_property commands.
This allows full control over cache entry information, so advanced users
can tweak their project cache as desired. The set_property command
allows only pre-defined CACHE properties to be set since others would
not persist anyway.
This moves the version numbers into an isolated configured header so
that not all of CMake needs to rebuild when the version changes.
Previously we had spaces, dashes and/or the word 'patch' randomly chosen
before the patch number. Now we always report version numbers in the
traditional format "<major>.<minor>.<patch>[-rc<rc>]".
We still use odd minor numbers for development versions. Now we also
use the CCYYMMDD date as the patch number of development versions, thus
allowing tests for exact CMake versions.
This cleans up the 'cmake --build' command-line interface:
- Rename --clean to --clean-first to better describe it.
- Replace --extra-options with a -- separator to simplify passing of
multiple native build tool options.
- Document the options in the main CMake man page description of the
--build option, and shares this with the usage message.
- Require --build to be the first argument when present.
- Move implementation into cmakemain where it belongs.
This teaches AddExternalProject to run "$(MAKE)" for build and install
steps of CMake-based external projects when using a Makefile generator.
It allows the external project to participate in a parallel make invoked
on the superproject.
This adds the OPTIONAL option to the install(DIRECTORY) command. It
tells the installation rule that it is not an error if the source
directory does not exist. See issue #8394.
This patch from Philip Lowman creates a REALPATH mode in the
get_filename_component command. It is like ABSOLUTE, but will also
resolve symlinks (which ABSOLUTE once did but was broken long ago).
See issue #8423.
The patch used to fix this bug used SystemTools::GetRealPath which works
only for existing files. It broke the case of using the command
get_filename_component for a non-existing file. Also, it changed
long-standing behavior in a possibly incompatible way even for existing
files. This reverts the original fix and instead updates the
documentation to be consistent with the behavior.
Isolation of policy changes inside scripts is important for protecting
the including context. This teaches include() and find_package() to
imply a cmake_policy(PUSH) and cmake_policy(POP) around the scripts they
load, with a NO_POLICY_SCOPE option to disable the behavior. This also
creates CMake Policy CMP0011 to provide compatibility. See issue #8192.
This teaches functions and macros to use policies recorded at creation
time when they are invoked. It restores the policies as a weak policy
stack entry so that any policies set by a function escape to its caller
as before.
Recently we taught find_package to re-find a package if its
<package>_DIR result variable was set to a location not containing the
package (instead of reporting an error as before). This tests the
feature.
The new 'testing' test behavior of actually running the tests generated
by the project still fails when the test script guesses the Debug
configuration but the CMake build tree was only built Release. The
inner ctest needs to find the ctest executable but is given the wrong
configuration.
The recent change of the 'testing' test to actually drive the tests
within it does not work on Windows with released CMakes 2.6.2 and lower
if no configuration is given to ctest with a -C option. This works
around the problem by detecting the case and changing the empty
configuration to Debug.
On Windows the KWSys System package generates escapes for command-line
arguments. This fix enables quoting of the empty string as an argument.
This also adds a test to pass an empty argument to a custom command.
The 'testing' CMake test builds a project that uses add_test. This
strengthens the test to actually run CTest on the project build tree
after building it.
We now search in
<prefix>/<name>*/
<prefix>/<name>*/(cmake|CMake)
when looking for package configuration files. This is useful on Windows
since the Program Files folder is in CMAKE_SYSTEM_PREFIX_PATH. These
paths are the Windows equivalent to the Apple convention application and
framework paths we already search. See issue #8264.
The $ENV{VAR} syntax permits access to environment variables. This
teaches CMake to recognize most characters in the VAR name since some
environments may have variables with non-C-identifier characters.
The previous change to test finding in lib/cmake/<name>* weakened the
versioned find tests. Since the lib/cmake paths are searched before
lib/<name>* paths the previous change skipped requiring the command to
ignore zot-3.0 when finding zot-3.1. This change restores that and adds
zot-4.0 to test the lib/cmake path.
This teaches find_package to search
<prefix>/(share|lib)/cmake/<name>*/
for package configuration files. Packages that do not already have
files in a <prefix>/lib/<name>* directory can use this location to avoid
cluttering the lib directory.
When CMake is built by CMake 2.4 or lower the FindCVS module is not
available. In that case we activiate CTest.UpdateCVS by searching for
the cvs command directly.
This creates new tests "CTest.UpdateSVN" and "CTest.UpdateCVS". They
test that the Update.xml produced by CTest for a version-controlled
project contains entries for files added, changed, and removed.
This adds a SOURCES option to ADD_CUSTOM_TARGET, enabling users to
specify extra sources for inclusion in the target. Such sources may not
build, but will show up in the IDE project files for convenient editing.
See issue #5848.
Recently we taught find_package that the NO_MODULE option is implied
when it is recursively invoked in a find-module. This behavior may be
confusing because two identical calls may enter different modes
depending on context. It also disallows the possibility that one
find-module defers to another find-module by changing CMAKE_MODULE_PATH
and recursively invoking find_package. This change reverts the feature.
Package version test files may now declare that they are unsuitable for
use with the project testing them. This is important when the version
being tested does not provide a compatible ABI with the project target
environment.
These changes teach find_package to behave nicely when invoked
recursively inside a find-module for the same package. The module will
never be recursively loaded again. Version arguments are automatically
forwarded.
Provide VERSION_LESS, VERSION_EQUAL, and VERSION_GREATER operators in
the if() command. This simplifies component-wise comparison of version
numbers in the form "major[.minor[.patch[.tweak]]]".
Make the number of version components specified explicitly available.
Set variables for unspecified version components to "0" instead of
leaving them unset. This simplifies version number handling for find-
and config-modules. Also support a fourth "tweak" version component
since some packages use them.
This introduces the unset() command to make it easy to unset CMake
variables, environment variables, and CMake cache variables. Previously
it was not even possible to unset ENV or CACHE variables (as in
completely remove them). Changes based on patch from Philip Lowman.
See issue #7507.
Some native build tools, particularly those for cross compiling, may
have a limit on the length of the full path to an object file name that
is lower than the platform otherwise supports. This change allows the
limit to be set by the project toolchain file through the variable
CMAKE_OBJECT_PATH_MAX.
It is useful to be able to test if a target has been created. Often
targets are created only inside conditions. Rather than storing the
result of the condition manually for testing by other parts of the
project, it is much easier for the other parts to just test for the
target's existence. This will also be useful when find-modules start
reporting results with IMPORTED targets and projects want to test if a
certain target is available.
We frequently need to wipe out all the CMake test build directories in
order to run tests from scratch. This change adds a test_clean custom
target to remove all these directories for out-of-source builds.
When creating an IMPORTED target for a library that has been found on
disk, it may not be known whether the library is STATIC or SHARED.
However, the library may still be linked using the file found from disk.
Use of an IMPORTED target is still important to allow per-configuration
files to be specified for the library.
This change creates an UNKNOWN type for IMPORTED library targets. The
IMPORTED_LOCATION property (and its per-config equivalents) specifies
the location of the library. CMake makes no assumptions about the
library that cannot be inferred from the file on disk. This will help
projects and find-modules import targets found on disk or specified by
the user.
Rename the recently added INTERFACE mode of the target_link_libraries()
command to LINK_INTERFACE_LIBRARIES. This makes it much more distinct
from a normal call to the command, and clearly states its connection to
the property of the same name. Also require the option to appear
immediately after the target name to make it a mode rather than an
option.
It is likely that projects or CMake modules in the future will need to
check the value of a policy setting. For example, if we add a policy
that affects the results of FindXYZ.cmake modules, the module code will
need to be able to check the policy.
A recent change fixed a case in which CMake incorrectly diagnosed a
circular dependency involving a non-linkable executable target. This
adds a test for that case.
As of CMake 2.6 a custom command output specified by relative path is
placed in the build tree. This adds a test to make sure other
references to the output are hooked up correctly, fixing a bug in CMake
2.6.1.
- Previously the find_* commands did not normalize the search paths
- The recent refactoring enabled such normalization
- The FindBase test must also normalize before comparing paths
- Option was recently added but never released.
- Custom commands no longer depend on build.make so we do
not need the option.
- Rule hashes now take care of rebuilding when rules change
so the dependency is not needed.
- Tests IMPLICIT_DEPENDS_INCLUDE_TRANSFORM properties.
- See issue #6648.
- Works without help in VS IDEs due to native dependency handling.
- Xcode needs help to rebuild correctly.
- Allows make rules to be created with no dependencies.
- Such rules will not re-run even if the commands themselves change.
- Useful to create rules that run only if the output is missing.
- Place the built library in foo.framework/Versions/A/foo
- Do not create unused content symlinks (like PrivateHeaders)
- Do not use VERSION/SOVERSION properties for frameworks
- Make cmTarget::GetDirectory return by value
- Remove the foo.framework part from cmTarget::GetDirectory
- Correct install_name construction and conversion on install
- Fix MACOSX_PACKAGE_LOCATION under Xcode to use the
Versions/<version> directory for frameworks
- Update the Framework test to try these things
- This will help projects support multiple CMake versions.
- In order to set a policy when using a newer CMake but still
working with an older CMake one may write
if(POLICY CMP1234)
cmake_policy(SET CMP1234 NEW)
endif(POLICY CMP1234)
- Note that since CMake 2.4 does not have if(POLICY) supporting
it will also require using "if(COMMAND cmake_policy)"
- Remove CMP_0001 (no slash in target name) and restore
old CMAKE_BACKWARDS_COMPATIBILITY check for it
- Replace all checks of CMAKE_BACKWARDS_COMPATIBILITY
with cmLocalGenerator::NeedBackwardsCompatibility calls
- Create new CMP_0001 to determine whether or not
CMAKE_BACKWARDS_COMPATIBILITY is used.
(old = use, new = ignore)
- Show CMAKE_BACKWARDS_COMPATIBILITY in cache only when
CMP_0001 is set to OLD or WARN
- Update documentation of cmake_policy and cmake_minimum_required
to indicate their relationship and the 2.4 version boundary
- When no cmake policy version is set in top level makefile
implicitly call cmake_policy(VERSION 2.4) which restores
CMAKE_BACKWARDS_COMPATIBILITY and other 2.4 compatibility
- Fix tests MakeClean and Preprocess to call
cmake_policy(VERSION 2.6) because they depend on new policies
- Motivation:
- It depended on the order of installation
- It supported only a single destination for each target
- It created directory portions of an install name without user request
- Updated ExportImport test to install targets in an order that expoed
this bug
- Split IMPORTED_LINK_LIBRARIES into two parts:
IMPORTED_LINK_INTERFACE_LIBRARIES
IMPORTED_LINK_DEPENDENT_LIBRARIES
- Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior
- Set mode to LINK for Darwin (fixes universal binary problem)
- Update ExportImport test to account for changes
- Added EXACT option to request an exact version.
- Enforce version using check provided by package.
- Updated FindPackageTest to test versioning in config mode.
- Imported bundles have the MACOSX_BUNDLE property set
- Added cmTarget::IsAppBundleOnApple method to simplify checks
- Document BUNDLE keyword in INSTALL command
- Updated IMPORTED_LOCATION property documentation for bundles
- Updated ExportImport test to test bundles
