From 4be92cf018c391c4ecc5fd091fae8c152de3692f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 15 Feb 2017 21:36:48 -0300 Subject: perf python: Filter out -specs=/a/b/c from the python binding cc options 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.
