* strings: Remove redundant calls to std::string::c_str()Nils Gladitz2014-10-151-13/+13
| | | | | Replacements were detected and performed by the clang tool remove-cstr-calls on a linux build.
* Fix some spelling errors in commentsGeoff Viola2014-10-131-3/+3

* enable_language: Fix error messages on missing modules (#15155)Brad King2014-09-181-6/+6
| | | | | | In cmGlobalGenerator::EnableLanguage, fix error messages for missing module files to actually name the missing module instead of using the empty string returned by GetModulesFile.
* enable_language: Initialize system-specific generator info only onceBrad King2014-09-101-20/+24
| | | | | | Call SetSystemName, SetGeneratorPlatform, and SetGeneratorToolset exactly once after reading CMakeSystem.cmake, and not again on another call to enable_language() or project().
* CMake: Add CMAKE_GENERATOR_PLATFORM optionBrad King2014-09-051-0/+29
| | | | | | | | | | | Reject the option by default. It will be implemented on a per-generator basis. Pass the setting into try_compile project generation. Add cache entry CMAKE_GENERATOR_PLATFORM and associated variable documentation to hold the value persistently. Add a RunCMake.GeneratorPlatform test to cover basic use cases for the option. Verify that CMAKE_GENERATOR_PLATFORM is empty by default, and that it is rejected when the generator does not support a user setting.
* cmGlobalGenerator: Call SetGeneratorToolset even for empty toolsetBrad King2014-09-051-11/+17
| | | | | | Move handling of an empty toolset name into the implementation of the method. This simplifies the VS 10 implementation of default toolset selection because it has one code path that is always called.
* ASM_MASM: Do not require compiler to be a full pathBrad King2014-08-131-1/+2
| | | | | The compiler detection modules for this language do not yet know how to find the full path to 'ml' or 'ml64', so do not require it.
* CMP0047: Fix CMAKE_COMPILER_IS_GNU(CC|CXX) in OLD behaviorBrad King2014-08-071-0/+8
| | | | | | | | | The implementation of CMP0047 detects the QNX compiler id internally, then changes it to GNU after the language is fully enabled. This is too late to correctly set the old IS_GNU variables, so set them as part of the policy OLD behavior. Reported-by: Mike Lattanzio <mlattanzio@blackberry.com>
* cmGlobalGenerator: Take Build output argument by referenceBrad King2014-07-311-44/+19
| | | | | | No call sites pass NULL to the output argument, so take it by reference to avoid the if(output) conditions. Propagate the change through the TryCompile APIs that call it.
* cmGlobalGenerator: Do not re-add CMAKE_<LANG>_COMPILERBrad King2014-07-241-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cmGlobalGenerator::ResolveLanguageCompiler method, invoked only by Makefile generators, contains code originally added by commit v2.4.0~796 (..., add new generators for msys and mingw, 2005-12-22) to compute the full path to the compiler and save the result back into the cache value. Since then the CMakeDetermine*Compiler modules have learned to resolve the full path to the compiler and save it in CMake*Compiler.cmake files configured in the build tree. The value of CMAKE_<LANG>_COMPILER in the cache is now only for reference of what the user originally specified. The full path is now available in a normal variable of the same name, and this is used by project code and the generators. When the user specifies -DCMAKE_<LANG>_COMPILER=name on the command-line of an existing build tree that uses a Makefile generator, it is first stored in the cache with an uninitialized type. Then later when ResolveLanguageCompiler updates the cache entry and sets the type to FILEPATH, cmMakefile::AddCacheDefinition does CollapseFullPath on the "name" and ends up with something like "$PWD/name" which is unlikely to be correct. Furthermore, cmMakefile::AddCacheDefinition proceeds to remove the normal variable of the same name, so the value originally saved in CMake<LANG>Compiler.cmake is ignored and the generators use the wrong path to the compiler. Resolve this by dropping the code from ResolveLanguageCompiler that touches the cache value of CMAKE_<LANG>_COMPILER. As explained above it is no longer needed anyway.
* cmGlobalGenerator: Create a non-virtual 'DoGenerate' methodBrad King2014-07-221-1/+6
| | | | | | | Make the virtual 'Generate' method protected. Make 'DoGenerate' the main entry point to generation. This gives cmGlobalGenerator a chance to do some early operations before the individual generator-specific implementations take over.
* Tell generators about CMAKE_SYSTEM_NAME as soon as it is knownBrad King2014-07-171-0/+8
| | | | | | | | | Add a cmGlobalGenerator::SetSystemName virtual method. Call it from cmGlobalGenerator::EnableLanguage as soon as CMAKE_SYSTEM_NAME is known. This will give generators a chance to adapt themselves to the target system. Pass the cmMakefile instance to the method so that the generator can update it accordingly. Return early from EnableLanguage if SetSystemName returns false.
* VS: Move VS-only API out of cmGlobalGeneratorBrad King2014-06-121-30/+0
| | | | | Move the IsDependedOn method to cmGlobalVisualStudio7Generator since that is the only caller.
* cmake: remove dummy backtraces for IssueMessageBen Boeckel2014-06-051-8/+4

* Allow a toolchain file to specify a generator toolsetBrad King2014-06-041-3/+12
| | | | | | | | | | | | | | | | | | | | Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake file has been configured and loaded during the first project() or enable_language() command. This gives the toolchain file named by CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET. This point is still early enough to set the generator toolset prior to the initialization of any languages that might use the toolset. The cmake::GeneratorToolset member variable remains an indication of what was specified by the -T option or loaded from the cache. It does not need to be updated based on the toolchain file setting. The cmMakefile::TryCompile can still pass cmake::GeneratorToolset into the inner instance because the try-compiled project will do platform and language initialization using the CMakeSystem module configured for the outer project. Extend the RunCMake.GeneratorToolset test with cases that use a toolchain file to set CMAKE_GENERATOR_TOOLSET.
* Add an "installed file" property scopeNils Gladitz2014-05-281-0/+44
| | | | | | | Teach set_property and get_property an "INSTALL" property type to be associated with install-tree file paths. Make the properties available to CPack for use during packaging. Add a "prop_inst" Sphinx domain object type for documentation of such properties.

| | * cmTarget: Make the source files depend on the config.Stephen Kelly2014-04-021-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Disallow the use of config-specific source files with the Visual Studio and Xcode generators. They don't have any way to represent the condition currently. Use the same common-config API in cmQtAutoGenerators. While it accepts config-specific files, it doesn't have to support multiple configurations yet. Loop over the configs in cmTargetTraceDependencies and cmGlobalGenerator::WriteSummary and consume all source files. Loop over the configs in cmComputeTargetDepends and compute the object library dependencies for each config.

| | * cmGeneratorTarget: Compute target objects on demandStephen Kelly2014-04-021-46/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a ComputeObjectMapping method to compute the object names. It takes mapping to populate as an out-parameter so that it can be extended in the future with parameters relevant to generator expression evaluation. Remove the supporting cmGeneratorTarget::AddObject method. It is no longer needed as the container member is populated directly. The ComputeObjectMapping method is called whenever objects are requested from the cmGeneratorTarget. Because the Xcode generator makes no such request, explicitly invoke the method from that generator so that the logic of checking for bad sources in object libraries is executed. In a follow-up, the UseObjectLibraries usage may be replaced by a true generator expression evaluator for TARGET_OBJECTS. That will require generators to use cmGeneratorTarget::GetExternalObjects which is not currently the case for Xcode and VS generators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Casts from std::string -> cmStdString were high on the list of things taking up time. Avoid such implicit casts across function calls by just using std::string everywhere. The comment that the symbol name is too long is no longer relevant since modern debuggers alias the templates anyways and the size is a non-issue since the underlying methods are generated since it's inherited.

Use VS 6 and 7 workaround from Brad King for lack of partial template specialization and function template specialization capabilities. This will make it possible to use context dependent generator expressions to determine the sources of a target.
| | * cmTarget: Find source files on request.Stephen Kelly2014-02-241-35/+0
| | | | | | | | | | | | | | | | | | In a follow-up, the list of sources will become dependent on the config, so check for existence in cmTarget::GetSourceFiles instead of up-front with cmGlobalGenerator::CheckTargets().
* | | Add platform-specific initialization step when enabling languagesBrad King2014-04-291-0/+15
|/ / | | | | | | | | | | | | | | Create a Modules/CMakeSystemSpecificInitialize.cmake module loaded after CMakeSystem.cmake but before per-language initialization. Use it to load an optional Platform/<os>-Initialize.cmake module. This will be useful to do per-platform initialization that does not depend on the language and use the results when enabling specific languages.
* | Do not warn by default when policy CMP0025 or CMP0047 is not setBrad King2014-04-021-2/+4
|/ | | | | | | | | | | | | | | | | | | | | These policies are triggered by the use of a particular compiler rather than outdated CMake code in a project. Avoid warning in every project that enables a language by not displaying the policy warning by default. Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning explicitly; otherwise enable the warning with --debug-output or --trace. This breaks with strict policy convention because it does not provide developers with any warning about the behavior change by default. Existing projects will continue to build without a warning or change in behavior. When a developer changes the minimum required version of CMake in a project to a sufficiently high value (3.0), the project will suddenly get the new compiler id and may break, but at least the breakage comes with a change to the project rather than the version of CMake used to build it. Breaking strict policy convention is worthwhile in this case because very few projects will be affected by the behavior change but every project would have to see the warning if it were enabled by default.
