* enable_language: Assume compiler works if ABI detection compilesBrad King2020-05-251-37/+38
| | | | | | | | | | | | | | | We run a `try_compile` with a tiny test source to check if the compiler works so that we can fail early if it does not. When the compiler does work, we immediately `try_compile` the ABI detection source. In the common case that both steps work, we gain no useful information from the first one and the work was wasted. Re-order the checks to try the ABI detection first. If it works then assume the compiler works and skip the dedicated check. If the ABI check fails then proceed with the normal test for a working compiler so the diagnostic can be shown as before. Fixes: #18703

* Improve formatting of compiler failure error messageBrad King2017-09-191-2/+3
| | | | | | When we report that a compiler was unable to build a simple test program, indent the output of the attempt so that our message formatting will show it as a pre-formatted block.
* Simplify CMake per-source license noticesBrad King2016-09-271-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* Features: Extend concept to C language.Stephen Kelly2014-05-141-0/+3
| | | | | | | | | | | Add properties and variables corresponding to CXX equivalents. Add features for c_function_prototypes (C90), c_restrict (C99), c_variadic_macros (C99) and c_static_assert (C11). This feature set can be extended later. Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader to conditionally represent the c_restrict feature.
* Drop use of configure_file IMMEDIATE optionDaniele E. Domenichelli2013-11-131-1/+1
| | | | | | Since commit 7d47c693 (Drop compatibility with CMake < 2.4, 2013-10-08) we no longer need to use the configure_file IMMEDIATE option to support compatibility modes less than 2.0.

| * Move CMAKE_<LANG>_COMPILER_WORKS to compiler information filesBrad King2012-08-241-16/+27
| | | | | | | | | | | | | | | | Since the parent commit this test result is specific to the version of CMake. Store it in the version-specific compiler information files instead of CMakeCache.txt so testing can be re-done to meet the requirements of the current version of CMake even if another version of CMake was already used to configure the build tree.
| * Make platform information files specific to the CMake versionBrad King2012-08-241-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the top of a build tree we configure inside the CMakeFiles directory files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to save information detected about the system and compilers in use. The method of detection and the exact results store varies across CMake versions as things improve. This leads to problems when loading files configured by a different version of CMake. Previously we ignored such existing files only if the major.minor part of the CMake version component changed, and depended on the CMakeCache.txt to tell us the last version of CMake that wrote the files. This led to problems if the user deletes the CMakeCache.txt or we add required information to the files in a patch-level release of CMake (still a "feature point" release by modern CMake versioning convention). Ensure that we always have version-consistent platform information files by storing them in a subdirectory named with the CMake version. Every version of CMake will do its own system and compiler identification checks even when a build tree has already been configured by another version of CMake. Stored results will not clobber those from other versions of CMake which may be run again on the same tree in the future. Loaded results will match what the system and language modules expect. Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to CMAKE_PLATFORM_INFO_DIR to clarify its purpose. The new variable points at the version-specific directory while the old variable did not.
* | VS: Simplify MSVC version reportingBrad King2012-08-301-5/+0
|/ | | | | | | | | Teach Windows-cl.cmake to use CMAKE_(C|CXX)_COMPILER_VERSION to set the "MSVC##" and MSVC_VERSION variables. It no longer needs the IDE generator to dictate the version or to detect the version by running the command-line tool for NMake and Ninja generators. Drop configuration of CMakeCPlatform.cmake and CMakeCXXPlatform.cmake from Windows-cl.cmake.in because all the results it saved are now cheap to compute every time.
* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-6/+6
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-30/+30
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed

* Load platform files that need to know the ABI when possibleBrad King2011-12-051-0/+6
| | | | | | | | Load platform files named in CMAKE_<lang>_ABI_FILES for each language once the ABI sizeof(void*) is known. During the first configuration this is after the test for working compiler and ABI detection checks. During later configurations the ABI information is immediately available because it has been saved in CMake<lang>Compiler.cmake.

* Load compiler information after configuring itBrad King2010-05-061-0/+1
| | | | | | | | | | | After configuring CMakeFiles/CMake<lang>Compiler.cmake in the build tree the second time (to store ABI information), include it immediately. This allows any logic and settings in the compiler information files to be used without duplicating it in CMakeDetermineCompilerABI.cmake. The change in commit "Use Fortran ABI detection results conservatively" (2010-05-05) needs this to use the same logic to set CMAKE_SIZEOF_VOID_P during first and later runs of CMake.
