Would it break anything if we changed check_cxx_compiler_flag to build a shared library instead of an executable? Maybe that will make the try_compile fail as expected. (I'll try add a test for that now)
We cannot make a change like that to such a widely used check. It will undoubtedly cause subtle behavior changes for other checks. You can use the source-tree signature of try_compile to build your own test project that creates a shared library and tries using that flag. BTW, the reason the compiler won't warn about -Wl,--no-undefined is because "-Wl," is the part parsed by the compiler. It then passes the --no-undefined option to the linker, and the linker is not warning. -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
