I thought you meant you would add the try_compile to the platform file to decide whether to report -fPIE. > Do you mean in the tests, or do you mean the POSITION_INDEPENDENT_CODE > feature should be disabled for older GCC? I mean that set(CMAKE_${lang}_COMPILE_OPTIONS_PIE "-fPIE") should not be done if the compiler does not have -fPIE. Therefore Modules/Compiler/GNU.cmake needs to test the compiler version to decide whether -fPIE is available. Likely other toolchains will need similar checks. -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://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
