1763c31 Set policy CMP0025 to NEW while building CMake itself
aa53ee5 Add policy CMP0025 for Apple Clang compiler id compatibility
ab65862 Clang: Add separate "AppleClang" compiler id
Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, the result variable would be set to
false, even if the struct has that particular member.
Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use. The new
signature is therefore:
CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable>
[LANGUAGE <language>])
This assumes that coverage.py has been run in such a way to produce its
standard XML output. This uses the Cobertura schema and should be somewhat
generalizable.
Add a new command line argument to ctest. This allows users to
rerun tests that failed during the previous call to ctest. This
is accomplished by analyzing the most recently modified file named
"^LastTestsFailed*" in the Testing/Temporary subdirectory of the
project's binary directory.
Add an unset() command option to remove a variable from the calling
scope, just like the set() command's PARENT_SCOPE option. Teach the
Unset test to cover such cases.
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id. Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.
Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.
Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.
Currently, export() is executed at configure-time.
One problem with this is that certain exported properties like
the link interface may not be complete at the point the export() is
encountered leading to an incorrect or incomplete exported
representation. Additionally, the generated IMPORTED_LOCATION
property may even be incorrect if commands following the export()
have an effect on it.
Another problem is that it requires the C++ implementation of cmake
to be capable of computing the exported information at configure time.
This is a limitation on the cleanup and maintenance of the code. At
some point in the future, this limitation will be dropped and more
implementation will be moved from cmTarget to cmGeneratorTarget.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.
The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.
An ALIAS target may be created for an INTERFACE library.
At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.
The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Re-insert the semicolon which was removed during splitting.
Commit d777b8e7 (Genex: Allow relative paths in INSTALL_INTERFACE.,
2013-07-25) introduced the prefixItems method to allow relative paths
in the argument of the INSTALL_INTERFACE expression. That method was
buggy in that it did not re-introduce the semicolon separator in
the result.
This bug also affects paths which are already absolute in user code.
The lack of Qt4 on a system should silently skip the corresponding tests
with no other messages. This is already the case for other find_package
calls in Tests/CMakeLists.txt.
Xcode 5.0 now relinks targets when their shared libraries dependencies
are modified, and there seems to be no way to stop it. Report this as a
known limitation in the test output and do not fail.
In Tests/Architecture and Tests/BuildDepends/Project we select a set of
OS X cpu architectures to use for the test. Prior to Xcode 4 we always
used i386 and ppc. Starting with Xcode 4, the tools do not support ppc
but do support x86_64, so we switch to that. Fix the version check to
recognize Xcode >= 5 as at least Xcode 4 and use the new architectures.
This is useful for cases like:
add_test(NAME mytest COMMAND mydriver $<TARGET_FILE:myexe>)
set_tests_properties(mytest PROPERTIES
REQUIRED_FILES "$<TARGET_FILE:myexe>"
WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}/$<CONFIGURATION>"
)
In this example we require the actual test executable to exist to
run the test in addition to the test driver at argv[0]. Also the
$<CONFIGURATION> expression improves over \${CTEST_CONFIGURATION_TYPE}
because the latter is not normalized for case-sensitive filesystems.
When RunCMake tests run during dynamic analysis, valgrind may add lines
of the form "==[0-9]+==..." to the output. Remove such lines from the
actual output before matching it against the expected output.
In commit 10bc50ea (Tests: ignore Guard Malloc messages in MemChecker
tests, 2013-05-13) we forgot to escape backslashes in the CMake language
to get them into the regex. Add them now.
Add the CMake.PolicyCheck test.
This test uses "git grep" to look for policies added in a "dated"
version of CMake. It will fail if a policy is added as of,
for example, CMake 2.8.11.20130828.
The intent is to prevent such constructs from making it into an
"official" release. Three instances actually appeared in the first
attempted release candidate for 2.8.12.
This test may sometimes yield false positives. After all, it's just
using a regular expression to detect this condition, and something
in a comment could possibly match it. As of right now, that's not
true, but it's easy to imagine such a comment being added.
The new test may also not catch all future problems of this sort.
However, it will catch problems of this sort for all code that follows
the present layout style in Source/cmPolicies.cxx.
The old version encountered a compile error on newer versions of GCC.
Update to the latest supported release of Trilinos, remove the version
number from the name of the Contract, and some other minor tweaks to
get the test passing once more.
This is necessary because custom commands and targets may create
custom files whose names are determined by generator expressions.
For example, clang should be using $<TARGET_FILE> and $<TARGET_FILE_DIR>
instead of reverse engineering the output file name:
http://thread.gmane.org/gmane.comp.compilers.clang.scm/80523
However, that can only be done when ADDITIONAL_MAKE_CLEAN_FILES
also accepts and evaluates generator expressions.
Similarly, KDE uses the LOCATION property where $<TARGET_FILE>
would also be better in KDE4_HANDLE_RPATH_FOR_EXECUTABLE but
also appends the result to ADDITIONAL_MAKE_CLEAN_FILES.
After this patch, both can be ported to generator expressions.
Exclude Ninja and Xcode from the CMP0021 test
They do not behave the same as the makefile generator with
relative paths.
Don't overwrite the header file for in-source builds.
