* Xcode: Detect CURRENT_ARCH for use by generatorBrad King2017-03-311-0/+5
| | | | | | | During compiler identification, extract the Xcode `CURRENT_ARCH` value and save it for later use by the Xcode generator in an internal compiler information variable. This will be useful to know the locations of object files when only one architecture is built.

* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

* Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596)Brad King2015-09-181-1/+0
| | | | | | | | Move detection over to the compiler id logic where we have already constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS. Pass the flags when we execute "cl" with "/showIncludes". Also pass "/c" because we only need to compile, not link. Check the compiler process exit code before trusting its output.

* | CMakeDetermineCompilerId: Optionally try some flags before no flagsBrad King2015-06-181-0/+1
|/ | | | | | | | Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the compiler id using some given flags before trying to detect it with no special flags. This will be useful for Fortran detection to distinguish some compilers that use the preprocessors of others but have no macro of their own by getting verbose output.
* Avoid if() quoted auto-dereferenceBen Boeckel2014-10-201-4/+4

| * Fix finding binutils when cross-compiling with ClangBrad King2014-09-051-1/+3
| | | | | | | | | | | | | | | | | | Since commit v3.0.0-rc1~342^2~2 (Add compiler target compile options, 2013-05-19) we use CMAKE_<LANG>_COMPILER_TARGET as the binutils prefix when cross-compiling with Clang. Fix the implementation to use the compiler target as the prefix only when it is set. Otherwise toolchain files not using CMAKE_<LANG>_COMPILER_TARGET cause the logic to use a prefix of just "-" and of course cannot find "-ar" or "-ld".

* Add compiler target compile options.Stephen Kelly2013-11-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | For clang, this allows passing -target <triple> to the compiler, and for qcc, -V<arch> using toolchain files containing something like set(triple arm-linux-gnueabihf) set(CMAKE_C_COMPILER "/usr/bin/clang") set(CMAKE_C_COMPILER_TARGET ${triple}) set(CMAKE_CXX_COMPILER "/usr/bin/clang++") set(CMAKE_CXX_COMPILER_TARGET ${triple}) or set(arch gcc_ntoarmv7le) set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc) set(CMAKE_C_COMPILER_TARGET ${arch}) set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC) set(CMAKE_CXX_COMPILER_TARGET ${arch}) Both clang and qcc are inherently cross compiler( driver)s. When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils. When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.

Remove the temporary cache entry afterward to avoid exposing it to projects. It is not set by other logic paths so no one should be using it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Re-organize CMakeDetermine(C|CXX|Fortran)Compiler.cmake to search for the compiler command-line tool only under generators for which it makes sense. For the Visual Studio generators we do not expect to find the compiler tool from the environment, nor would we use the result anyway. Furthermore, set CMAKE_${lang}_COMPILER_ID_TEST_FLAGS only when it has a chance to be used. Extract _CMAKE_TOOLCHAIN_LOCATION from the compiler path after running the compiler id step so in the future that step can help find the path to the compiler.

* Prefer generic system compilers by default for C, C++, and FortranBrad King2012-08-021-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach CMake to prefer the system default compiler automatically when no compiler is specified. By default use "cc" for C, "CC" for C++, and "f95" for Fortran. Load a new Platform/<os>-<lang>.cmake module to allow each platform to specify for each language its system compiler name(s) and/or exclude certain names. Create Platform/(CYGWIN|Darwin|Linux|Windows)-CXX.cmake modules to specify "c++" as the system C++ compiler name for these platforms. On systems that use case-insensitive filesystems exclude C++ compiler names that are distinguished from C compiler names only by case. This will change the default compiler selection for existing build scripts that do not specify a compiler when run on machines with separate system and GNU compilers both installed in the PATH. We do not make this change in default behavior lightly. However: (1) If a given build really needs specific compilers one should specify them explicitly e.g. by setting CC, CXX, and FC in the environment. (2) The motivating case is to prefer the system Clang on newer OS X systems over the older GNU compilers typically also installed. On such systems the names "cc" and "c++" link to Clang. This is the first platform known to CMake on which "c++" is not a GNU compiler. The old behavior selected "gcc" for C and "c++" C++ and therefore chooses GNU for C and Clang for C++ by default. The new behavior selects GNU or Clang consistently for both languages on older or newer OS X systems, respectively. (3) Other than the motivating OS X case the conditions under which the behavior changes do not tend to exist in default OS installations. They typically occur only on non-GNU systems with manually-installed GNU compilers. (4) The consequences of the new behavior are not dire. At worst the project fails to compile with the system compiler when it previously worked with the non-system GNU compiler. Such failure is easy to work around (see #1). In short this change creates a more sensible default behavior everywhere and fixes poor default behavior on a widely-used platform at the cost of a modest change in behavior in less-common conditions.
* Factor common code out of CMakeDetermine(ASM|C|CXX|Fortran)CompilerBrad King2012-08-021-12/+5
| | | | | | | | | | | | | | | | | The compiler candidate list selection and search code for C, C++, ASM, and Fortran languages was duplicated across four modules. To look for compilers adjacent to already-enabled languages the C and CXX modules each used _CMAKE_USER_(C|CXX)_COMPILER_PATH and the ASM module used _CMAKE_TOOLCHAIN_LOCATION. Since commit 4debb7ac (Bias Fortran compiler search with C/C++ compilers, 2009-09-09) CMake prefers Fortran compilers matching the vendor and directory of an enabled C or C++ compiler. Factor out the common functionality among the four languages into a new CMakeDetermineCompiler module. Generalize the Fortran implementation so that all languages may each use the vendor and directory of the other languages that have already been enabled. For now do not list any vendor-specific names for C, C++, or ASM so that only the directory preference is used for these languages (existing behavior).
* CMakeDetermine(C|CXX)Compiler: Consider Clang compilersBrad King2012-07-311-1/+1

* Set CMAKE_<lang>_COMPILER_ID for VS generatorsBrad King2011-09-021-4/+1
| | | | | | | | | | | | | Currently the VS generators do not support Intel C/C++ .icproj files and the MS tools do not include a Fortran compiler. Therefore we can always set the C and CXX compiler IDs to "MSVC" and the Fortran ID to "Intel". This fixes a regression in support for the Intel Fortran compiler under the VS plugin introduced by commit cd43636c (Modernize Intel compiler info on Windows, 2010-12-16). The commit moved the compiler information into platform files that only load when the proper compiler id is set. It worked for the NMake Makefiles generator but not for the VS IDE generator because it did not set the compiler id.
