We enumerate processes to identify those whose parent is being killed so
that we can recursively kill the children. Enumeration uses the
Process32(First|Next) windows API functions, which accept PROCESSENTRY32
objects to be filled. This commit corrects the declaration of the entry
structure to account for its size on 64-bit Windows.
On UNIX systems we kill a tree of processes by performing a DFS walk of
the tree. We send SIGSTOP to each process encountered, recursively
handle its children, and then send SIGKILL.
We once used the above approach in the past, but it was removed by the
commit "Do not send both SIGSTOP and SIGKILL when killing a process".
The commit was meant to work-around an OS X 10.3 bug in which the child
would not always honor SIGKILL after SIGSTOP. At the time we wrongly
assumed that the process tree remains intact after SIGKILL and before
the child is reaped. In fact the grandchildren may be re-parented to
ppid=1 even before the child is reaped, which causes the DFS walk to
miss them.
The Watcom tools do their own command-line parsing and do not accept
double-quotes. Instead we single-quote the target output name when
invoking wlink and other Watcom tools. This fixes support for spaces in
the target output directory path when it is not under the build tree.
We create CMake Policy CMP0015 to make link_directories() treat relative
paths with respect to the source tree while retaining compatibility.
This makes it consistent with include_directories() and other commands.
Changes based on patch from Alex. See issue #9697.
In CTest command-driven script mode we support starting without a source
tree. Previously the ctest_start() command would do some initialization
but could not do anything that required CTestConfig.cmake from the input
source tree. Later, ctest_update() would run CTEST_CHECKOUT_COMMAND to
create the source tree, and then re-initialize everything. This
delayed-initialization approach led to many complicated cases of which
only some worked. For example, the second initialization only worked
correctly in Nightly mode and simply failed for Experimental and
Continuous builds.
A simpler solution is to run CTEST_CHECKOUT_COMMAND during ctest_start()
and then have a single initialization path. In principle this change in
behavior could break scripts that set the checkout command after
ctest_start() but before ctest_update(). However, the convention we've
always followed has been to set all variables before ctest_start().
See issue #9450.
We make the cmCTest::Initialize method private since it is only called
from inside the class implementation. We also combine the two boolean
arguments into one since they both meant the same thing.
We suppress Intel warning 1572 because the cases where we do equality
tests are valid. Since this project does not do numerical computations
we need not worry about real instances against which this warning
protects.
-use CMAKE_EXECUTABLE_FORMAT and CMAKE_SYSTEM_NAME to decide which binary
parsers to load (ELF/Mach O/PE)
-use CMAKE_(C|CXX)_COMPILER_ID to load the respective compiler error parser
-remove EclipseToolchainType, which was a mixture between compiler and operating system

The commit "Enable loose loop constructs in KWSys" set the minimum
required CMake version to 2.4.5. This regressed the setting of CMP0003,
so we restore it in this commit.
The FundamentalType header needs to know type sizes at preprocessing
time. This commit teaches it to avoid using CHECK_TYPE_SIZE because the
macro does not work for types whose size varies across architectuers in
Mac OS X universal binaries. Fortunately the Mac compilers provide just
enough information to detect the needed type sizes during preprocessing.
We now use preprocessor macros instead of configuration tests whenever
they are available. As a side effect this reduces the number of
try-compiles needed with GCC.
See issue #9913.
This macro helps KWSys perform try-compile tests that extract 'INFO'
strings out of compiled binaries. It works for CMake 2.6 and above.
On CMake 2.4 it always returns an empty list of information values,
so this should be used only as an optimization until 2.6 is required.
In KWSys IOStream we need to detect whether 'long long' exists but we do
not need its size. We avoid using CHECK_TYPE_SIZE because it does not
work for types whose size varies across architectuers in Mac OS X
universal binaries. See issue #9913.
The list of libraries to be linked into the current target must be
specified using windows slashes to that UNC paths such as
\\server\share\somelibrary.lib
work correctly. See issue #9917.
VS 10 provides $(Configuration) and $(ConfigurationName) but only the
former is documented so we prefer it. This also makes CMAKE_CFG_INTDIR
consistent with its documentation. See issue #9916.
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.
The ctest subdirs command now checks the relative path first, and if that does not exist, also checks if the given path was absolute. Thanks vodall for the patch.
Previously we silently ignored such calls and set nothing. The commit
"Initialize directory scope with closure of parent" inroduced a bad test
for the top scope. This commit fixes the test to avoid dereferencing a
null pointer, and adds a warning when the case is encountered.
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.
We create per-configuration target properties to specify ARCHIVE,
LIBRARY, and RUNTIME output directories. The properties override the
generic properties for the <CONFIG> configuration:
ARCHIVE_OUTPUT_DIRECTORY -> ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
LIBRARY_OUTPUT_DIRECTORY -> LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
RUNTIME_OUTPUT_DIRECTORY -> RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
For multi-configuration generators, the per-configuration subdirectory
normally appended to the generic output directory is not added to the
configuration-specific property values. This allows projects to set the
exact location at which binaries will be placed for each configuration.
See issue #9163.
VS 6 forgets to create the output directory for a static library if it
differs from the intermediate files directory. We work around this VS
bug by creating a pre-link event on the library target to make the
directory.
This commit removes use of configuration-less cmTarget::GetDirectory()
by the VS 6 generator (except for compatibility with user templates).
We replace OUTPUT_DIRECTORY_<CONFIG> tokens in the templates using the
per-configuration result of cmTarget::GetDirectory(config).
The try_compile() command's COPY_FILE option should not try to actually
copy the file if it cannot be found. Some C runtime library's fopen
cannot handle an empty file name.
Previously the Xcode generator set SYMROOT to be the target output
directory. This told Xcode to put the "<proj>.build" directory in the
output path too.
This commit sets SYMROOT, CONFIGURATION_BUILD_DIR, and OBJROOT to put
intermediate files in the build directory corresponding to the source
directory that created each target. This is more consistent with the VS
IDE generators. Now only the build output files (actual targets) go to
the target output directory.
The commit "modified the if command to address bug 9123 some" changed
the if() command behavior with respect to named boolean constants. It
introduced policy CMP0012 to provide compatibility. However, it also
changed behavior with respect to numbers (like '2') but did not cover
the change with the policy. Also, the behavior it created for numbers
is confusing ('2' is false).
This commit teaches if() to recognize numbers again, and treats them
like the C language does in terms of boolean conversion. We also fix
the CMP0012 check to trigger in all cases where the result of boolean
coersion differs from that produced by CMake 2.6.4.
The if() command reports its arguments at the beginning of some error
messages. Originally it reported the un-expanded form of the arguments
because in ancient CMake versions no context information was available.
Now it is more useful to see the real arguments, which may be mentioned
in the main error message. Since full context information is now
available, users can refer back to the source if they need to see the
unexpanded form of the arguments.
For example, the code
set(regex "++")
if("x" MATCHES "${regex}")
endif()
now produces the message
if given arguments:
"x" "MATCHES" "++"
Regular expression "++" cannot compile
instead of
if given arguments
"x" MATCHES "${regex}"
Regular expression "++" cannot compile
The commit "Set version info for shared libs on OSX" taught the Xcode
generator to honor VERSION and SOVERSION properties. However, it also
set version '1.0.0' as the default when no version property is set,
which is inconsistent with the Makefiles generator. This commit fixes
the default to '0.0.0' for consistency.
See issue #9773.
The reverted commit attempted to preserve the "../" PREFIX work-around
for avoiding per-config build directories in the VS IDE generators.
However, the original reporter has concluded that a "../" PREFIX no
longer works everywhere in VS 10 project files anyway. Rather than set
OutputPath, this commit restores the $(OutDir)$(TargetName)$(TargetExt)
default.
See issue #9768.
This commit fixes the cmparseMSBuildXML.py script to generate correct
flag table entries for booleans with optional value. These flags use
two entries: the first should ignore the value and enable the option,
and the second should use the value if given. Previously the first
entry did not recognize flags with values.
In particular this fixes flags like /MP4, but the change corrects
matching of some other flags too. See issue #9771.
This commit teaches the VS 10 generator to detect the -D_UNICODE option
in preprocessor definitions and set the CharacterSet attribute to the
value 'Unicode'. This was already done for other VS IDE versions.
See issue #9769
The default $(OutDir)$(TargetName)$(TargetExt) for this value works in
most cases because we set the three properties. However, if the target
property PREFIX contains a path component (not documented but happens to
work in other VS generators) we drop it from TargetName and do not put
it in OutDir either. This commit corrects the resulting path by setting
the OutputPath property explicitly with the full path.
See issue #9768.
Intel Fortran on Mac OS X enables Fortran support in Xcode. This commit
teaches CMake to associate Fortran sources properly in Xcode projects.
See issue #9739.
The VS 10 flag table generation script did not produce correct entries
for precompiled header flags. Since precompiled header flag translation
requires multiple entries cooperating in a certain order, it is not
worth the time to make the generation script work automatically. This
commit manually adds the proper entries.
See issue #9753.
MS changed the location of the Microsoft.Cpp.$(Platform).user.props
file. This commit teaches the VS 10 generator about the new location.
See issue #9759.
Versioned UNIX libraries and executables produce multiple names for a
single target using one of
cmake -E cmake_symlink_library
cmake -E cmake_symlink_executable
to create symlinks to the real file for the extra names. However, when
cross-compiling from Windows to Linux we cannot create symlinks. This
commit teaches CMake to make copies instead of symbolic links when
running on windows. While this approach does not produce exactly what
Linux wants to see, at least the build will complete and the binary will
run on the target system. See issue #9171.
During installation of a target we generate "tweak" rules to update the
installed file (RPATH, strip, ranlib, etc.). However, some targets
install multiple files, such as the versioned names of a shared library.
Previously the extra files for a target have always been symbolic links,
but for cross-compiling from Windows to UNIX they may need to be copies.
This commit teaches the generated install scripts to loop over all files
installed for the target to apply tweaks to those that are not symlinks.
See issue #9171.
In cmInstallTargetGenerator::GenerateScriptForConfig we were computing
the full 'from' paths for all target files to be installed, but only
computing a 'to' path for the "main" target file. This commit teaches
the method to compute both 'from' and 'to' paths for every target file
to be installed. The result is cleaner, easier to follow, and will
allow installation tweaks to be added later on all target files.
We factor the implementation of
cmake -E cmake_symlink_library
cmake -E cmake_symlink_executable
out of cmake::ExecuteCMakeCommand into methods
cmake::SymlinkLibrary
cmake::SymlinkExecutable
plus a helper method cmake::SymlinkInternal.
The cmInstallTargetGenerator methods AddStripRule and AddRanlibRule do
not need the target type argument. They can simply use the type of the
target for which the generator instance was created.
The CMAKE_OSX_ARCHITECTURES variable works only as a global setting.
This commit defines target properties
OSX_ARCHITECTURES
OSX_ARCHITECTURES_<CONFIG>
to specify OS X architectures on a per-target and per-configuration
basis. See issue #8725.
Both generators use the CMAKE_EDIT_COMMAND variable to determine whether
they should add the edit_cache target, i.e. they don't add it if it's
ccmake, since this does not work inside the output log view of
Eclipse/Codeblocks. But instead of requiring the variable to be set they now
check it for 0 and handle this appropriately. This should help Dave getting
some testing for them :-)

In VS 8 and greater this commit implements
add_dependencies(myexe mylib) # depend without linking
by adding the
LinkLibraryDependencies="false"
option to project files. Previously the above code would cause myexe to
link to mylib in VS 8 and greater. This option prevents dependencies
specified only in the solution from being linked. We already specify
the real link library dependencies in the project files, and any project
depending on this to link would not have worked in Makefile generators.
We were already avoiding this problem in VS 7.1 and below by inserting
intermediate mylib_UTILITY targets. It was more important for those
versions because if a static library depended on another library the
librarian would copy the dependees into the depender! This is no longer
the case with VS 8 and above so we do not need that workaround.
See issue #9732.
In Visual Studio project files we pass compiler flags to the whole
target based on the linker language, which works for MS tools and
combinations of C and C++. For the Intel Fortran plugin though the
generated .vfproj files should never contain C or C++ options.
We generate .vfproj files only for targets consisting only of Fortran
code. Now that the linker language is computed transitively through
linking it is possible that the linker language is C++ for an otherwise
Fortran-only project. This commit forces Fortran as the linker language
for the purpose of specifying target-wide flags in .vfproj files.
See issue #9719.
The commit "Avoid non-root copies of root-only targets" moved the check
for root-only targets into cmGlobalGenerator::GetTargetSets to avoid
adding multiple ALL_BUILD targets to the "original" target set. This
approach did not work for ZERO_CHECK targets though because those are
pulled in by dependency analysis.
Instead we eliminate duplicate ZERO_CHECK targets altogether and refer
to a single one from all solution files. This cleans up VS 10 project
file references to ZERO_CHECK targets anyway.
We revert commit "Create CMake Policy CMP0015 to fix set(CACHE)" because
the NEW behavior of the policy breaks a valid use case:
# CMakeLists.txt
option(BUILD_SHARED_LIBS "..." ON)
add_library(mylib ...)
set(BUILD_SHARED_LIBS OFF) # we want only mylib to be shared
add_subdirectory(ThirdParty)
# ThirdParty/CMakeLists.txt
option(BUILD_SHARED_LIBS "..." ON)
# uh, oh, with NEW behavior this dir uses shared libs!!!
We'll re-introduce the policy later with a different change in behavior
to resolve the motivating case, which was more subtle but less common.
See issue #9008.
The commit "Really fix color check for dependency scanning" disabled
color unless "make COLOR=ON" is specified. This restores the previous
default behavior when CMAKE_COLOR_MAKEFILE is ON while retaining the
previous commit's fix. See issue #9680.
The commit "Fix color check for dependency scanning" was meant to
disable color if CMAKE_COLOR_MAKEFILE was off. It did remove use of the
activation option '--color' but it failed to make the default false when
the option was missing. This commit corrects that. See issue #9680.
The commit "add support for borland run time flag for shared builds"
started using the value of CMAKE_SHARED_LIBRARY_CXX_FLAGS to link
executables because Borland requires some flags both at compile and link
time. This change ended up propagating all the way to the current
Makefile generators and the behavior applies on all platforms.
In general it is incorrect to use these flags to link executables. The
commit "Split Borland compiler information files" re-wrote Borland
support to work without this behavior, so we remove it in this commit.
Patch from Ben Hutchings. See issue #9659.
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.
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.
In cmMakefile::AddCacheDefinition we collapse paths specified in PATH or
FILEPATH cache entries originally specified on the command line with
UNINITALIZED type. This commit fixes the logic to avoid collapsing
<var>-NOTFOUND and other false values. The change allows other CMake
code to force a NOTFOUND value on an entry with UNINITALIZED type.
The commit "Support more special characters in file(STRINGS)" added code
using a 'char' literal as an array index. Some compilers warn about
this because char might be a signed type, leading to negative indices.
We replace the literal with an integer to avoid the warning.
The commits "Teach Fortran compiler identification about the Portland
Group compiler" and "Fix previous change to file(STRINGS) command"
taught file(STRINGS) to recognize the form-feed '\f' character as part
of string literals. The Portland Group Fortran compiler also puts 0x14
bytes at the end of string literals in some cases. We generalize the
previous solution and add the new character in this commit.
Scanning the dependencies for kdelibs/khtml/ (when all files are scanned) is
now down to 4.6 s from 6.3 s before this change (without the
headerLocationCache it takes about 14 s here).
It doesn't really make sense to include the complete include path as part
of the key for the map, since the include path will be the same for
all files in a project, so it doesn't add anything.
Alex
In cmGlobalGenerator::GetTargetSets we collect targets from all local
generators in a tree or subtree corresponding to a project() command.
Some targets, such as ALL_BUILD, are duplicated in each subdirectory
with a project() command. For such targets we should keep only the copy
for the top-most (root) local generator.
Previously this filtering was done in each VS IDE generator, but it is
easier to do it in one place when the targets are first encountered.
This also fixes bad ALL_BUILD dependencies generated for VS 7.0 because
the cmGlobalVisualStudio7Generator::WriteTargetDepends method was not
filtering out duplicates. Now we avoid duplicates from the start.
