Fix check for -isysroot on OS X Previously we checked for this flag by parsing the version number of GCC out of 'gcc --version', but this is not reliable because the format can vary greatly. Now we run 'gcc -v --help' and look for '-isysroot' in the list of options. We also now store the result on a per-language basis in the per-compiler info file "CMake<LANG>Compiler.cmake". This is necessary to make it accessible from try-compile projects so that they generate correctly. 2009-09-19 18:14:31 +04:00			`include(Platform/Darwin-GNU)`
Fix OS X dylib and module GNU flags The commit "Split GNU compiler information files" broke the settings of CMAKE_SHARED_LIBRARY_CREATE_${lang}_FLAGS CMAKE_SHARED_MODULE_CREATE_${lang}_FLAGS and started using just "-shared" for them. This worked when tested on newer Mac machines, but older ones really need "-dynamiclib" and "-bundle" (which are the documented flags anyway). 2009-12-02 23:09:03 +03:00			`__darwin_compiler_gnu(CXX)`
OS X: Always generate -isysroot if any SDK is in use Drop the last use of CMAKE_OSX_SYSROOT_DEFAULT. Replace internal platform variable CMAKE_${lang}_HAS_ISYSROOT with a more general CMAKE_${lang}_SYSROOT_FLAG variable. If the -isysroot flag exists and CMAKE_OSX_SYSROOT points to an SDK (not "/") then always add it to compiler command lines. This is already done in the Xcode IDE. 2012-09-21 16:53:42 +04:00			`cmake_gnu_set_sysroot_flag(CXX)`
Fix issue #10155 - default value of CMAKE_OSX_DEPLOYMENT_TARGET should always be the empty string. When the value of CMAKE_OSX_DEPLOYMENT_TARGET is the empty string, the -mmacosx-version-min flag should not show up on the compiler command line. The logic for selecting default value of CMAKE_OSX_SYSROOT is orthogonal to and independent of the value of the deployment target. The default value for CMAKE_OSX_SYSROOT is the SDK that corresponds to the current version of Mac OSX on which cmake is running. 2010-01-29 19:56:35 +03:00			`cmake_gnu_set_osx_deployment_target_flag(CXX)`
