* launcher: support setting a compiler launcher through the environmentBen Boeckel2019-12-051-0/+5
| | | | | | This makes it much easier to use a launcher for all CMake projects in an environment rather than having to remember to pass the setting to every CMake build.
* Modules: Introduce CMAKE_EFFECTIVE_SYSTEM_NAME to lookup compiler infoGregor Jasny2018-04-181-4/+4
| | | | | | | | | Create a `CMAKE_EFFECTIVE_SYSTEM_NAME` variable to use for looking up compiler information modules instead of using `CMAKE_SYSTEM_NAME` directly. This will allow multiple platforms to share the same set of compiler information modules without spelling out all of them. Issue: #17870
* Unhardcode the CMAKE_CONFIGURATION_TYPES valuesBeren Minor2018-01-081-31/+1
| | | | | | | | | | | | This removes duplicated code for per-config variable initialization by providing a `cmake_initialize_per_config_variable(<PREFIX> <DOCSTRING>)` function. This function initializes a `<PREFIX>` cache variable from `<PREFIX>_INIT` and unless the `CMAKE_NOT_USING_CONFIG_FLAGS` variable is defined, does the same with `<PREFIX>_<CONFIG>` from `<PREFIX>_<CONFIG>_INIT` for every `<CONFIG>` in `CMAKE_CONFIGURATION_TYPES` for multi-config generators or `CMAKE_BUILD_TYPE` for single-config generators.
* Do not initialize CMAKE_BUILD_TYPE on multi-config generatorsBastien Schatt2017-04-061-2/+4
| | | | | | Use the `GENERATOR_IS_MULTI_CONFIG` global property to reliably detect multi-config generators regardless of what variables the project or user have set.
* 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

* Revert "Disable shared library support when compiler links statically" (#15855)Brad King2015-11-231-4/+0
| | | | | | | | In commit v3.4.0-rc1~18^2 (Disable shared library support when compiler links statically, 2015-09-30) we tried to detect when the compiler is not capable of linking shared libraries (possibly due to flags in use). However, the approach is not robust against flags like `-nostdlib`. Revert it for now pending another solution to the original problem.
* Disable shared library support when compiler links staticallyBrad King2015-09-301-0/+4
| | | | | | | | | When a user or a compiler wrapper adds '-static' to the compiler flags then it will always link static binaries. Detect this from the compiler id binary and disable TARGET_SUPPORTS_SHARED_LIBS. This will prevent projects from accidentally adding shared libraries when the toolchain does not support them. It also helps CMake avoid linking with flags that require shared libraries to be supported.
* Re-order 'ar' options 'cq' => 'qc'Brad King2015-09-091-1/+1
| | | | | | | | | | | The documetnation of binutils: https://sourceware.org/binutils/docs/binutils/ar-cmdline.html suggests to use the parameters "q" and "c" in this order ("q" is operation, and "c" is the modifier). Suggested-by: Дилян Палаузов <dilyan.palauzov@aegee.org>
* Factor an <INCLUDES> placeholder out of <FLAGS> in rule variablesBrad King2015-07-131-1/+1
| | | | | | | | | | | Teach the Makefile and Ninja generators to substitute for an <INCLUDES> placeholder instead of putting -I in <FLAGS>. Update our values for CMAKE_<LANG>_COMPILE_OBJECT, CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE to place <INCLUDES> just before <FLAGS>.
* Support duplicate object names in large archives (#14874)Brad King2014-04-161-2/+2
| | | | | | | | | Generalize the change from commit 39d0ade0 (Windows-GNU: Support duplicate object names in large archives, 2014-04-14) to the default archive rules. These rules have used an incremental append approach since commit v2.8.0~1856 (Build large archives incrementally, 2008-08-04). Switch from "ar r" to "ar q" to be sure we always append objects instead of replacing them.

* Make CMAKE_(C|CXX|Fortran)_<CONFIG> help strings more consistent (#14606)Brad King2013-12-021-2/+2
| | | | | Use consistent capitalization and write all words out in the cache entry descriptions.
* Fix CMAKE_(C|CXX|Fortran)_RELEASE helpstrings (#14606)Brad King2013-12-021-1/+1
| | | | | Remove the platform-specific description from the cache entry help strings for these variables.
* Quote ${CMAKE_<LANG>_COMPILER} while enabling a languageBrad King2013-10-221-1/+1
| | | | | | | | | | | | Even though this variable gets set to CMAKE_<LANG>_COMPILER-NOTFOUND when the compiler is not found, CMake<LANG>Compiler.cmake gets removed by cmGlobalGenerator::EnableLanguage so in try compiles the value is empty. Quote references to the variable in Modules/CMake(C|CXX|Fortran)Information.cmake Modules/CMakeDetermineCompilerId.cmake to avoid dropping arguments from commands that expect them.
* Remove CMake-language block-end command argumentsKitware Robot2012-08-131-22/+22
| | | | | | | | | | | | | | | | | Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style. Run the following shell code: for c in else endif endforeach endfunction endmacro endwhile; do echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | egrep -z -v 'Tests/CMakeTests/While-Endwhile-' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Convert CMake-language commands to lower caseKitware Robot2012-08-131-100/+100
| | | | | | | | | | | | | | | | | Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code: cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done >convert.sed && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' | egrep -z -v '^(Utilities/cm|Source/kwsys/)' | xargs -0 sed -i -f convert.sed && rm convert.sed
* Remove trailing whitespace from most CMake and C/C++ codeKitware Robot2012-08-131-6/+6
| | | | | | | | | | | | | | | | | Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'
* Support building shared libraries or modules without soname (#13155)Modestas Vainius2012-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a boolean target property NO_SONAME which may be used to disable soname for the specified shared library or module even if the platform supports it. This property should be useful for private shared libraries or various plugins which live in private directories and have not been designed to be found or loaded globally. Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and hard-coded -install_name flags with a conditional <SONAME_FLAG> which is expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG definition as long as soname supports is enabled for the target in question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in rules in case third party projects still use it. Such projects would not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since -install_name is soname on OS X, this should not be a problem if this variable is expanded only if soname is enabled. The Ninja generator performs rule variable substitution only once globally per rule to put its own placeholders. Final substitution is performed by ninja at build time. Therefore we cannot conditionally replace the soname placeholders on a per-target basis. Rather than omitting $SONAME from rules.ninja, simply do not write its contents for targets which have NO_SONAME. Since 3 variables are affected by NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if soname is enabled.
* 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.

| * Fix relative CMAKE_USER_MAKE_RULES_OVERRIDE (#11725)Brad King2011-01-191-5/+9
| | | | | | | | | | | | | | | | | | In commit 295b5b60 (Honor CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) we started passing the value of this variable when building a try_compile project. If the variable contains a relative path it must be treated with respect to the file where it is first used. Ensure that the value is converted to a full path so that it is correctly referenced in the try_compile projects.
* | Allow platform files to set large archive rules (#11674)Brad King2011-01-101-3/+9
| | | | | | | | | | | | | | | | | | | | Commit aaa88d33 (Build large archives incrementally, 2008-08-04) hard-coded rules to create static archives incrementally in each language information file. Set each rule conditionally to allow compiler and platform information files to override the language default rules. Inspired-by: Harald Pohl <pohl.h@eppendorf.de>
* | Reset platform/compiler info status for each languageBrad King2010-09-281-0/+2
| | | | | | | | | | | | | | | | | | | | In each CMake<lang>Information.cmake file we use an _INCLUDED_FILE variable to track whether a compiler information file has been loaded. Reset this variable for each language. This fixes Fortran under VS generators with the Intel plugin. Previously the variable would be left set true from C and C++ and then Fortran would not load old-style files like Platform/Windows-ifort.

* Use work-around from bug 4772 for C++ and FortranBrad King2009-10-061-6/+5
| | | | | | | | | | | | | | The commit "fix for bug 4772" added a work-around to CMakeCInformation for platform config files that put compiler information in the system file (like SunOS flags for GCC). This commit adds the same work-around for CXX and Fortran. It is necessary to support enabling these languages separately from C in other subdirectories. The commit "Avoid (Unix|Windows)Paths.cmake multiple include" added include blockers that prevent the files from multiple inclusion, so it is safe to include the system information files from every language. See issue #4772 and issue #9656.
* 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: Load platform-independent per-compiler filesBrad King2009-07-231-0/+6
| | | | | | | This teaches the language configuration modules to load per-compiler information for each language using the compiler id but no system name. They look for modules named "Compiler/<id>-<lang>.cmake". Such modules may specify compiler flags that do not depend on the platform.

No interface has changed. - Create cmComputeLinkInformation class - Move and re-implement logic from: cmLocalGenerator::ComputeLinkInformation cmOrderLinkDirectories - Link libraries to targets with their full path (if it is known) - Dirs specified with link_directories command still added with -L - Make link type specific to library names without paths (name libfoo.a without path becomes -Wl,-Bstatic -lfoo) - Make directory ordering specific to a runtime path computation feature (look for conflicting SONAMEs instead of library names) - Implement proper rpath support on HP-UX and AIX.
