I am trying to run the unit tests for an application (that is only header files) in the%check section of the RPM spec file, running cmake on both gcc and clang with %optflags macro on Fedora rawhide. According to the guideline https://docs.fedoraproject.org/en-US/packaging-guidelines/#_compiler_flags , it seems %optflags macro works with both gcc and clang without the restriction for a specific compiler. This cmake command for gcc works. ``` CC=gcc CXX=g++ cmake .. \ -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \ -DCMAKE_C_FLAGS="%{optflags}" \ -DCMAKE_CXX_FLAGS="%{optflags}" %make_build ``` But this cmake command for clang does not work with the error "clang-10: error: unknown argument: '-fstack-clash-protection'". The used clang version is 10.0.0. Should %{optflags} work for both gcc and clang? Is it a bug of the %optflags macro? ``` CC=clang CXX=clang++ cmake .. \ -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \ -DCMAKE_C_FLAGS="%{optflags}" \ -DCMAKE_CXX_FLAGS="%{optflags}" %make_build ``` The log is here. ``` + CC=clang + CXX=clang++ + cmake .. -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON '-DCMAKE_C_FLAGS=-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection' '-DCMAKE_CXX_FLAGS=-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection' -- The C compiler identification is Clang 10.0.0 -- The CXX compiler identification is Clang 10.0.0 -- Check for working C compiler: /usr/bin/clang -- Check for working C compiler: /usr/bin/clang - broken CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:60 (message): The C compiler "/usr/bin/clang" is not able to compile a simple test program.
