The ``code`` must contain at - least a ``main()`` function. If the code could be built and run successfully, - the internal cache variable specified by ``resultVar`` will be set to 1, - otherwise it will be set to an value that evaluates to boolean false (e.g. - an empty string or an error message). - - The underlying check is performed by the :command:`try_run` command. The - compile and link commands can be influenced by setting any of the following - variables prior to calling ``check_c_source_runs()``: - - ``CMAKE_REQUIRED_FLAGS`` - Additional flags to pass to the compiler. Note that the contents of - :variable:`CMAKE_C_FLAGS <CMAKE_<LANG>_FLAGS>` and its associated - configuration-specific variable are automatically added to the compiler - command before the contents of ``CMAKE_REQUIRED_FLAGS``. - - ``CMAKE_REQUIRED_DEFINITIONS`` - A :ref:`;-list <CMake Language Lists>` of compiler definitions of the form - ``-DFOO`` or ``-DFOO=bar``. A definition for the name specified by - ``resultVar`` will also be added automatically. - - ``CMAKE_REQUIRED_INCLUDES`` - A :ref:`;-list <CMake Language Lists>` of header search paths to pass to - the compiler. These will be the only header search paths used by - ``try_run()``, i.e. the contents of the :prop_dir:`INCLUDE_DIRECTORIES` - directory property will be ignored. - - ``CMAKE_REQUIRED_LIBRARIES`` - A :ref:`;-list <CMake Language Lists>` of libraries to add to the link - command. These can be the name of system libraries or they can be - :ref:`Imported Targets <Imported Targets>` (see :command:`try_run` for - further details). - - ``CMAKE_REQUIRED_QUIET`` - If this variable evaluates to a boolean true value, all status messages - associated with the check will be suppressed. - - The check is only performed once, with the result cached in the variable - named by ``resultVar``. Every subsequent CMake run will re-use this cached - value rather than performing the check again, even if the ``code`` changes. - In order to force the check to be re-evaluated, the variable named by - ``resultVar`` must be manually removed from the cache. - -#]=======================================================================] - -macro(CHECK_C_SOURCE_RUNS SOURCE VAR) - if(NOT DEFINED "${VAR}") - set(MACRO_CHECK_FUNCTION_DEFINITIONS - "-D${VAR} ${CMAKE_REQUIRED_FLAGS}") - if(CMAKE_REQUIRED_LIBRARIES) - set(CHECK_C_SOURCE_COMPILES_ADD_LIBRARIES - LINK_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}) - else() - set(CHECK_C_SOURCE_COMPILES_ADD_LIBRARIES) - endif() - if(CMAKE_REQUIRED_INCLUDES) - set(CHECK_C_SOURCE_COMPILES_ADD_INCLUDES - "-DINCLUDE_DIRECTORIES:STRING=${CMAKE_REQUIRED_INCLUDES}") - else() - set(CHECK_C_SOURCE_COMPILES_ADD_INCLUDES) - endif() - file(WRITE "${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src.c" - "${SOURCE}\n") - - if(NOT CMAKE_REQUIRED_QUIET) - message(STATUS "Performing Test ${VAR}") - endif() - try_run(${VAR}_EXITCODE ${VAR}_COMPILED - ${CMAKE_BINARY_DIR} - ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/src.c - COMPILE_DEFINITIONS ${CMAKE_REQUIRED_DEFINITIONS} - ${CHECK_C_SOURCE_COMPILES_ADD_LIBRARIES} - CMAKE_FLAGS -DCOMPILE_DEFINITIONS:STRING=${MACRO_CHECK_FUNCTION_DEFINITIONS} - -DCMAKE_SKIP_RPATH:BOOL=${CMAKE_SKIP_RPATH} - "${CHECK_C_SOURCE_COMPILES_ADD_INCLUDES}" - COMPILE_OUTPUT_VARIABLE OUTPUT) - # if it did not compile make the return value fail code of 1 - if(NOT ${VAR}_COMPILED) - set(${VAR}_EXITCODE 1) - endif() - # if the return value was 0 then it worked - if("${${VAR}_EXITCODE}" EQUAL 0) - set(${VAR} 1 CACHE INTERNAL "Test ${VAR}") - if(NOT CMAKE_REQUIRED_QUIET) - message(STATUS "Performing Test ${VAR} - Success") - endif() - file(APPEND ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeOutput.log - "Performing C SOURCE FILE Test ${VAR} succeeded with the following output:\n" - "${OUTPUT}\n" - "Return value: ${${VAR}}\n" - "Source file was:\n${SOURCE}\n") - else() - if(CMAKE_CROSSCOMPILING AND "${${VAR}_EXITCODE}" MATCHES "FAILED_TO_RUN") - set(${VAR} "${${VAR}_EXITCODE}") - else() - set(${VAR} "" CACHE INTERNAL "Test ${VAR}") - endif() - - if(NOT CMAKE_REQUIRED_QUIET) - message(STATUS "Performing Test ${VAR} - Failed") - endif() - file(APPEND ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeError.log - "Performing C SOURCE FILE Test ${VAR} failed with the following output:\n" - "${OUTPUT}\n" - "Return value: ${${VAR}_EXITCODE}\n" - "Source file was:\n${SOURCE}\n") - - endif() - endif() -endmacro() - |
