It doesn't have to link. We can parse the compiler id out of object files. Look at lines in CMakeDetermineCCompiler that set CMAKE_C_COMPILER_ID_TEST_FLAGS We already try compiling with just "-c" to get an object file. Add the equivalent flag for this compiler if necessary. Basically we just try with no flag, and then with each of the flags listed in this variable. After each build we scan all files for the compiler id. If the object file is there it should work. -Brad _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
