See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: Arnaldo Carvalho de Melo The -spec=/path/to/file can be used to change what gcc puts in the cc, ld, etc command lines, but this is not present in clang, filter it out at the setup.py file by changing python2's internal variable where it keeps its initial CFLAGS value. With this all of perf can be built in at least Fedora 25, fixing this problem: GEN /tmp/build/perf/python/perf.so CC /tmp/build/perf/builtin-buildid-list.o clang-4.0: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument] clang-4.0: error: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1' [-Werror,-Wunused-command-line-argument] error: command 'clang' failed with exit status 1 Now I need to change all the containers where I have clang to build perf with it, so that we can check that in other distros (opensuse, debian, ubuntu, etc) this also works.
