Hey all, I’m trying to build my package for EPEL and got a strange error clang-11: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument] clang-11: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1' [-Werror,-Wunused-command-line-argument] https://kojipkgs.fedoraproject.org//work/tasks/653/69120653/build.log The relevant section of the spec file is: %build export CXX=clang++ export CC=clang %cmake -G Ninja . %cmake_build Is this a bug, or something I’m doing wrong? If it is a bug I’d be happy to file a ticket in Bugzilla, but I’m not sure which project to file it under.
Some of the default Fedora flags aren't supported by clang, so if you build in clang you need to use the clang equivalents of those flags. In rawhide, you can enable the correct flags by setting the macro: %global toolchain clang I'm not sure if this macro is supported in EPEL, though, so you may need to manually update the flags yourself. -Tom
