# Compute the directory in which to run the test.
Make platform information files specific to the CMake version 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.

QNX: Introduce QCC compiler id for that QNX platform compiler. Introduce policy CMP0047 to control resetting the id for compatibility. De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

Provide conversion macros DEC() and HEX() to decode decimal or hex digits from integer values. Parse the version out of the compiler id binary along with the other INFO values already present. Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format "major[.minor[.patch[.tweak]]]". Save the value persistently in CMake(C|CXX)Compiler.cmake in the build tree. Document the variable for internal use since we do not set it everywhere yet. Report the compiler version on the compiler id result line e.g. The C compiler identification is GNU 4.5.2 Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

CMakeDetermineCompilerId: Add notion of "simulated" id/version Some compilers try to simulate other compilers as a drop-in replacement supporting all the same command-line options and predefined preprocessor macros.

CMakeDetermineCompilerId: Fix Intel Fortran compiler id detection The Intel Fortran compiler needs the /fpp option to enable C preprocessing. Without the option the compiler may warn and ignore preprocessor lines instead of failing with an error. Detect the warning and treat it as failure so that we move on to try /fpp and detect the correct id. Without this it works only by luck because Intel is the first compiler id in our detection source file.

QNX: Introduce QCC compiler id for that QNX platform compiler. Introduce policy CMP0047 to control resetting the id for compatibility. De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

De-duplicate content in the QNX platform file by including the GNU one. QNX is a form of GNU platform. Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables. They are populated again later by the Compiler/GNU.cmake file anyway. Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC compiler id is in use, and the language is CXX. Use the QNX recommended flag for QCC instead of the gcc compatible -x flag. Populate new module files to handle system includes and depfiles when using the QCC compiler. Remove code which unsets the system include and depfiles related variables. When a GNU driver is used instead of the QCC one, the appropriate flags will be used. These variables were previously cleared for lowest-common-denominator compatibility with both drivers.

Make platform information files specific to the CMake version 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.

Add timeout to execute_process() in CMAKE_DETERMINE_COMPILER_ID(). In CMAKE_DETERMINE_COMPILER_ID_VENDOR() the compiler is called with various arguments. In some cases, this can make the compiler hang and wait forever for input (e.g. "as -v"). That's why add an timeout so it terminates finally. 10 seconds should be more than enough, this is the time it takes to startup the compiler, which is usually quite fast. Alex

Convert CMake-language commands to lower case 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

Remove CMake-language block-end command arguments 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
