| * Features: Allow setting standard dialect below the default.Stephen Kelly2015-02-041-1/+15
| | | | | | | | | | If the requested standard dialect is older than the default dialect then we must use a flag because we cannot decay to a newer standard.
| * Features: Add dialect compile flags only if default is known.Stephen Kelly2015-02-041-9/+9
| | | | | | | | | | | | | | | | | | The CMAKE_<LANG>_STANDARD_DEFAULT variable indicates whether the compiler has any notion of standard levels and that CMake knows about them. If no language standard levels are available, skip all logic to attempt to add a flag for the level. Also fail with an internal error if a bad default value is set.

| * install: Fix regression in default configuration selectionBen Boeckel2015-02-031-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | The refactoring in commit v3.1.0-rc1~812^2~16 (stringapi: Pass configuration names as strings, 2014-02-09) broke the code path in cmLocalGenerator::GenerateInstallRules that intends to pick a default install configuration for multi-config generators. Fix the logic to select an empty default configuration only when using a single-config generator whose CMAKE_BUILD_TYPE is not set.

* | Features: Define meaning for no language standard defaultBrad King2015-01-291-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that the toolchain has no notion of lanuage standard levels. In this case the <LANG>_STANDARD[_REQUIRED] properties will have no effect. Update the RunCMake.CompileFeatures test to exclude the LinkImplementationFeatureCycle test when there is no standard default. It can never fail because no use of specific features will adjust the CXX_STANDARD level required for any target since the standard levels have no meaning in this case.

* | file: Add LOCK subcommand to do file and directory lockingRuslan Baratov2014-12-031-0/+6
| | | | | | | | | | | | | | | | | | Provide options to fail without blocking or to block up to a timeout. Provide options to specify the scope containing the lock so it can be released automatically at the end of a function, file, or process. Extend the RunCMake.file test with cases covering the file(LOCK) command usage and error cases.
* | file(GENERATE): Evaluate early to allow generating source filesStephen Kelly2014-11-121-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The evaluation files must be known before cmTargetTraceDependencies attempts to find them, but we must actually generate the files after cmTargetTraceDependencies, as that can add to target SOURCES. The limitation is that the generated output name must not depend on the SOURCES of a target if the generated file is used by that target. Mark the output files as GENERATED so that trace dependencies does not expect them to already exist in the filesystem. Move the invokation of ForceLinkerLanguage in the Generate logic to after the generated file names are known. ForceLinkerLanguage tries to determine the sources of a target (in order to determine an already-known language) and otherwise fails to get information about the generated file. Test that the output of file(GENERATE) can be used as a target source file and that accessing the target SOURCES in the name of the output file is an error. Accessing the TARGET_OBJECTS would be a similar error if it was legal to use that generator expression in this context. That is not currently possible and is a different error condition, so test the current error output as a reminder to change the expected output if that becomes possible in the future. Test that generated rule files resulting from cmTargetTraceDependencies appear in the SOURCES generated in the output file.
* | strings: Remove redundant calls to std::string::c_str()Nils Gladitz2014-10-151-19/+19
|/ | | | | Replacements were detected and performed by the clang tool remove-cstr-calls on a linux build.
* Ninja: Fix RC include directories regressionBrad King2014-10-131-3/+6
| | | | | | | | | | | | | | | | | Changes in commit b9aa5041 (cmLocalGenerator: Simplify GetIncludeFlags output formatting, 2014-03-04) caused Windows Resource Compiler include directories to be computed as relative paths in the Ninja generator. This breaks the cmcldeps handling of include paths. The reason for the regression is that several cmLocalGenerator::GetIncludeFlags callers treated the fourth "bool forResponseFile" argument as if it controlled whether include directories were a full path. It actually did control that by accident until the above commit. Add an explicit "bool forceFullPaths" argument to GetIncludeFlags and thread the value through ConvertToIncludeReference as needed. Update GetIncludeFlags call sites that really wanted to control the forResponseFile setting to be aware of the new argument. Extend the VSResource test to cover this case.

* | Fix some generator crashes on undefined CMAKE_BUILD_TYPEBrad King2014-06-231-1/+1
|/ | | | | | | | | | Since commit 84fdc9921 (stringapi: Pass configuration names as strings, 2014-02-09), it is not safe to use GetDefinition("CMAKE_BUILD_TYPE") without checking the return value. Use GetSafeDefinition instead so that a missing definition is treated as an empty string like code paths did prior to the above commit. Reported-by: Richard Wirth <richard@califax.de>
* Features: Escape the COMPILE_OPTIONS for dialects.Stephen Kelly2014-06-131-2/+5
| | | | | Allow for future handling as a list, not a string which may contain whitespace.
* Add OBJECT_FILE_DIR rule placeholder for compilation linesBrad King2014-06-051-0/+7
| | | | | | | | | Some compilers do not offer an option to specify the path to the object file, but rather only to the directory in which to place the object file. See issue 14876 for some examples. Add a new OBJECT_FILE_DIR placeholder to specify the directory containing the object file for the current compilation. This may differ from the main target OBJECT_DIR when the object corresponds to a source in a subdirectory.
* Features: Enable compiler extensions by default.Stephen Kelly2014-05-311-2/+10
| | | | | | | | | | | Compilers enable their extensions by default, and disabling them implicitly can lead to results which are surprising or non-obvious to debug. http://public.kitware.com/pipermail/cmake-developers/2014-May/010575.html http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/10214 https://www.mail-archive.com/cmake-developers@cmake.org/msg10116.html (Compiler feature extensions by default, 29 May 2014)

* | Features: Add COMPILE_FEATURES generator expression.Stephen Kelly2014-05-211-0/+25
|/ | | | | | | | | | | | Allow setting build properties based on the features available for a target. The availability of features is determined at generate-time by evaluating the link implementation. Ensure that the <LANG>_STANDARD determined while evaluating COMPILE_FEATURES in the link implementation is not lower than that provided by the INTERFACE of the link implementation. This is similar to handling of transitive properties such as POSITION_INDEPENDENT_CODE.

| | | | | | | | | | | Add properties and variables corresponding to CXX equivalents. Add features for c_function_prototypes (C90), c_restrict (C99), c_variadic_macros (C99) and c_static_assert (C11). This feature set can be extended later. Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader to conditionally represent the c_restrict feature.

This supports use-cases like set(CMAKE_CXX_STANDARD 14) # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14 # or equivalent flag add_executable(main main.cpp) This can be used in combination with preprocessor defines which communicate the availability of certain language features for optional use.
