* ASM compiler detection: remove debug output (#13270)Alex Neundorf2012-06-121-6/+0
| | | | | | This must have been left in accidentially. Alex
* Add framework to detect compiler version with its id (#12408)Brad King2011-12-071-2/+16
| | | | | | | | | | | | | | | | | | | | Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler. 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.

* Add timeout to execute_process() in CMAKE_DETERMINE_COMPILER_ID().Alex Neundorf2010-08-171-3/+10
| | | | | | | | | | | 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
* Detect a COMPILER_ID also for ASM.Alex Neundorf2010-08-151-0/+11
| | | | | | | | | | | | | | | For assembler, the "compiler ID" cannot be detected by "compiling" a source file, since there is not source file all assemblers understand. Instead the function CMAKE_DETERMINE_COMPILER_ID_VENDOR() is used to run the assembler and check its output. For this the CMAKE_DETERMINE_COMPILER_ID_VENDOR() function had to be extended so that it creates the run directory if it doesn't exist yet. In CMakeASMInformation.cmake now also CMAKE_ASM_COMPILER_ID is used (but there are no such files yet, will come with the support for the IAR toolchain). Alex

* Support multiple arguments in CC,CXX,FC valuesBrad King2010-03-151-0/+1
| | | | | | | | | Teach compiler identification to support values such as export CC='gcc -g -O2' by separating the arguments on spaces. We already do this for the values of CFLAGS, CXXFLAGS, and FFLAGS.
* Add alternate per-vendor compiler id detectionBrad King2010-02-011-0/+40
| | | | | | | At least one Fortran compiler does not provide a preprocessor symbol to identify itself. Instead we try running unknown compilers with version query flags known for each vendor and look for known output. Future commits will add vendor-specific flags/output table entries.

* Convert CMake non-find modules to BSD LicenseBrad King2009-09-281-0/+13
| | | | | | | This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.

* ENH: Improvied compiler identification robustnessBrad King2008-02-251-37/+39
| | | | | | | | - Write a single source file into the compiler id directory - This avoid requiring the compiler to behave correctly with respect to include rules and the current working directory - Helps to identify cross-compiling toolchains with unusual default behavior

Please have a look a CMakeDetermineCompilerId.cmake and enable the test for them too. Only add the option for using chrpath if the executable format is ELF Alex

* ENH: UNIX, CYGWIN, WIN32, APPLE, QNXNTO and BEOS are not longer set inAlexander Neundorf2007-08-091-2/+2
| | | | | | | | | | | | | | cmMakefile.cxx, but now in the platform files and are now valid for the target platform, not the host platform. New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be used in all cmake files which are executed before CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old set is set to the new one in CMakeDetermineSystem.cmake and reset before the system platform files are loaded, so custom language or compiler modules which use these should still work.

* ENH: add option to FILE(STRINGS NO_HEX_CONVERSION) to disable automaticAlexander Neundorf2007-05-251-0/+2
| | | | | | | | | | | | | | | | | | | conversion of hex and srec files to binary. Without this automatic conversion, everywhere where a compiled file is parsed for strings the a file(HEX2BIN somefile binfile) command has to be added otherwise it will not work for these compilers. I tried this with DetermineCompiler and CheckTypeSize and nobody will do this except the users who work with such compilers. For them it will break if they don't add this conversion command in all these places. If FILE(STRINGS) is used with a text file, it will in most cases still work as expected, since it will only convert hex and srec files. If a user actually wants to get text out of hex files, he knows what he's doing and will see the hint in the documentation. Anyway, it should work without having to create a temporary file, will work on this later. Alex
