From: Eduardo Habkost Date: Fri, 5 Oct 2018 20:40:58 +0000 (-0300) Subject: perf python: More portable way to make CFLAGS work with clang X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8b2f245faa6238e28a1d801e8633515251d1acfc;p=linux.git perf python: More portable way to make CFLAGS work with clang The existing code that tries to make CFLAGS compatible with clang doesn't work with Python 3. Instead of trying to touch _sysconfigdata.build_time_vars directly, change the dictionary returned by disutils.sysconfig.get_config_vars(). This works on both Python 2 and Python 3.
