When computing runtime search path ordering a constraint exists when a
file that may be found by the runtime search exists in a directory other
than that containing the desired file. We test whether a potential
conflict is really the same due to a symlink. Recently the change to
cmFindLibraryCommand to load directory content created a case in which
the same-file check would be incorrectly skipped. This avoids skipping
the check.
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.
When ctest --build-and-test runs the --test-command its output did not
quote the arguments of the command being tested making it difficult to
read. This adds the quotes. This also changes the wording of the
failure case to not sound like CTest could not run the executable when
in fact it ran and returned failure.
When CTest encounters a test whose executable is the ctest executable
iteslf, it just invokes code inside itself to avoid starting a new
process. This fixes a null-pointer dereference in the logging code of
that case.
The command argument lexer was recently regenerated which erased some
fixes that had been applied directly to the output. This restores the
fixes and adds reminder notes in the generation instructions.
The command argument parser code is generated by bison. This change
restores some fixes previously applied to the generated output that were
destroyed by regenerating the parser source. This time the fixes have
been put in the input file so regenerating the parser will not destroy
them again.
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.
For bug #7191.
Improvements to the dialog that sets up the first configure.
Fixing the large size of it by breaking it up into a wizard.
Also incorporated suggestions from bug report.
When the find_package command loads a <name>-version.cmake file to test
the package version it must prevent the version file from affecting
policy settings. Therefore the policy settings must be pushed and
popped.
Generated cmake_install.cmake script code used MATCHES to compare
component names. This does not support characters considered special by
regular expression syntax in component names. This change uses STREQUAL
instead. See issue #8256.
When an object file directory is too deep to place an object file
without exceeding CMAKE_OBJECT_PATH_MAX, this issues a warning.
Previously we silently ignored the problem. See issue #7860.
When computing the maximum length full path to the build directory under
which object files will be placed, pass the actual path instead of just
its length. This will be useful for error message generation.
The CMAKE_<CONFIG>_POSTFIX variable and <CONFIG>_POSTFIX property were
not documented. This updates the CMAKE_DEBUG_POSTFIX and DEBUG_POSTFIX
documentation to refer to the more general variable/property. It also
clarifies that the variable is used as the property default only for
non-executable targets. See issue #7868.
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 the find_package command loads a module it sets several
<pkg>_FIND_XXX variables to communicate information about the command
invocation to the module. This restores the original state of the
variables when the command returns. This behavior is useful when a
find-module recursively calls find_package with NO_MODULE so that the
inner call does not change the values in the find-module.
When we install a target on Mac, we generate a call to install_name_tool to fix
install_name entries in the target for shared libraries it links. This change
makes the step ignore entries for imported targets since their install_name
will not change and cmTarget cannot produce a mapping for them. This fixes the
error
GetLibraryNamesInternal called on imported target: kdelibs
seen by kde folks.
executing a ctest script so the search paths are fully set up and variables
like CMAKE_SYSTEM are available. This is useful e.g. for new-style ctest
scripting.
(these files are also loaded on startup by cpack, so now they behave
similar).
Hmmm, maybe they should be also loaded by cmake -P ?

The output of "cvs update" contains a line such as one of
cvs update: `foo.txt' is no longer in the repository
cvs update: foo.txt is no longer in the repository
cvs update: warning: foo.txt is not (any longer) pertinent
when file "foo.txt" has been removed in the version to which the update
occurs. Previously only the first case would be recognized. This fixes
the regular expression to match all these cases.
KWSys component dependencies must be enforced before any tests for
enabled components are done. This moves the dependency enforcement code
to be as early as possible.
We use response files to list object files for the MSVC linker. The
linker complains if any response file is greater than 128K, so we split
the object file lists into multiple response files.
Previously generation of object file lists for linker and cleaning
command lines was duplicated for library and executable target
generators. This combines the implementations.
This clarifies documentation of the find_* commands' PATH_SUFFIXES
option. The option adds paths with the suffixes but does not remove the
paths without the suffixes.
In cmFindBase we were searching all path suffixes appended to all paths
before considering the paths without any suffixes. Instead we should
consider each path with and without suffixes before moving to the next
path. See issue #7783.
This adds a missing default constructor to cmListFileContext that makes
sure the line number is initialized to zero. A zero line number will
indicate a generated context.
Applying patch provided in issue #7797.
Fixes to man-pages:
- Character '-' must be espaced as '\-'
- Surround preformatted text with '.nf' and '.fi' to adjust filling
- Give every page a NAME section for indexing by mandb
- Pass the man page filename without extension to .TH in its header
Also added a title to the HTML header.
These changes refactor cmLocalGenerator methods Convert and
ConvertToOutputForExisting to support references inside the build tree
using relative paths. After this commit, all tests pass with Makefile
generators when relative paths are enabled by default. See issue #7779.
The cmMakefile::DefineFlagsOrig ivar was created to help preserve the
old DEFINITIONS property behavior now that definitions are moved from
DefineFlags to the COMPILE_DEFINITIONS directory property. This fixes
propagation of the original value into subdirectories.
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.
After creating a utility target with AddUtilityCommand, return a pointer
to the cmTarget instance so the caller may further modify the target as
needed.
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.
We generate convenience rules to build object files, preprocessed
outputs, and assembly outputs of source files individually with make
rules. This removes a redundant working directory change when more than
one target builds the same source file.
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.
In single-configuration generators a target installation rule should
apply to all configurations for which the INSTALL command was specified.
The configuration in which the target is built does not matter.
In multi-configuration generators each installation rule must be
associated with a particular build configuration to install the proper
file. The set of configurations for which rules are generated is the
intersection of the build configurations and those for which the INSTALL
command was specified.
In SharedForward, the call to execvp warned on MinGW because the
signature declared in process.h has an extra const. We use an explicit
cast to convert the pointer type.
To detect when the launcher is running from the build tree we now test
if the directory containing it is the same as the build-tree directory
using an inode test instead of string comparison. This makes it more
robust on case-insensitive filesystems and other quirky situations.
If the arguments to a command fail to parse correctly due to a syntax
error, the command should not be invoked. This avoids problems created
by processing of commands with bad arguments. Even though the build
system will not be generated, the command may affect files on disk that
persist across CMake runs.
We now properly report the source location of command arguments inside
macros instead of using the macro invocation site. No information is
lost because full call-stack information is already reported.
Previously error messages produced by parsing of command argument
variable references, such as bad $KEY{VAR} syntax or a bad escape
sequence, did not provide good context information. Errors parsing
arguments inside macro invocations gave no context at all. Furthermore,
some errors such as a missing close curly "${VAR" would be reported but
build files would still be generated.
These changes teach CMake to report errors with good context information
for all command argument parsing problems. Policy CMP0010 is introduced
so that existing projects that built despite such errors will continue
to work.
Automatic generation of 64-bit library search paths must preserve
trailing slashes. This fixes a failure case exposed by the recent
rewrite of find_library, which assumes trailing slashes occur on all
search paths.
OpenBSD shared libraries use a ".so.<major>.<minor>" extension and do
not have a symlink with just a ".so" extension. Its "ld" is capable of
finding the library with the best version. This change adds support for
finding such libraries. See issue #3470.
Previously we searched for library files by enumerating every possible
combination of prefix and suffix. Now we load (and cache) directory
content from disk and search for matching file names. This should
reduce disk access. It will also allow more advanced matching rules in
the future. See issue #3470.
Previously the cmGlobalGenerator::GetDirectoryContent method would work
safely only during build system generation. These changes make it safe
to use during each configure step by flushing it at the beginning.
When looking for NOTFOUND libraries, use the direct dependencies of a
target instead of all dependencies. At least one target will trigger
the NOTFOUND error anyway because at least one must directly link it.
This removes another use of the old-style link line computation.
In some cases it may be useful to compute a "link" line for a static
library even though it will not be put in the generated build system.
This removes the assertion which previously diallowed the case.
In cmComputeLinkInformation items in the final link line returned by
GetItems now contain a pointer to their corresponding cmTarget if they
were produced by a target. This makes available the set of all targets
linked.
In cmGlobalGenerator we use cmComputeTargetDepends to construct a safe,
non-circular set of inter-target dependencies. This change enables use
of the results by the Xcode generator. It also removes a lot of old
code and another use of the old-style linking logic. See issue #7652.
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.
Use the new-style error reporting mechanism to provide more context
information for a find_package call with a bad package name. When the
package is not required, issue a warning instead of an error.
The set_property command unsets a property if it is given no value. In
the case of GLOBAL properties, the cmake::SetProperty method would
replace a NULL value with "NOTFOUND". Instead it should be left as NULL
so that the property is unset as expected. Once it is unset the
get_cmake_property command will still report NOTFOUND while the
get_property command will return the empty string as documented.
When the -C or --build-config option is used to specify the
configuration to be tested by CTest, do not override it with the
configuration in which CTest is built.
A Mac OS X Framework should provide a Resources/Info.plist file
containing meta-data about the framework. This change generates a
default Info.plist for frameworks and provides an interface for users to
customize it.
This change cleans up the implementation of cmXCodeObject to avoid
un-escaping and re-escaping string values. There is no need to store
the string in escaped form. It can be escaped once when it is printed
out to the generated project file.
The recent fix to avoid including flags in dependency inferral also
dropped them from chaining of dependencies through targets. This fix
restores chaining of flags through known dependency lists while still
leaving them out of inferred dependency lists.
This change introduces a new algorithm for link line construction. The
order it computes always begins with the exact link line specified by
the user. Dependencies of items specified by the user are tracked, and
those that are not already satisified by the line are appended to it at
the end with minimal repeats. This restores the behavior of CMake 2.4
and below while still fixing some of its bugs. See issue #7546.
In cmComputeLinkDepends link items that look like flags (starting in
'-') should not be included in dependency inferral. They are not
libraries and therefore have no dependencies. They should just be
passed through to the final link line unchanged. See issue #7546.
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.
According to "man select" on Linux it is possible that select() lies
about data being ready on a pipe in some subtle cases. We deal with
this by switching to non-blocking i/o and checking for EAGAIN. See
issue #7180.
