New submission from Calvin Walton: On Exherbo, the main C/C++ compilers are named e.g. "x86_64-pc-linux-gnu-cc" and "x86_64-pc-linux-gnu-c++", and they are symlinks to either (usually) gcc or (rarely) clang.
Since distutils (in unixccompiler.py) is checking for the substring "gcc" or "g++" in the compiler name, this does not match our compiler - and the "-Wl," prefix is missing, resulting in link errors in some cases. (We are particularly noticing this when doing gobject-introspection builds via cmake, where giscanner uses distutils to build the link command) As far as I know, all major compilers on Linux require the -Wl, option to pass through linker options - clang actually interprets -R without -Wl, to mean something completely different. We are planning to locally patch distutils to have an additional condition to the gcc check, `sys.platform[:5] == "linux" or self._is_gcc(compiler):` in our distribution to work around the issue. I'll attach patches once they're prepared, but I'd appreciate feedback about the problem. ---------- components: Distutils messages: 251546 nosy: Calvin Walton, dstufft, eric.araujo priority: normal severity: normal status: open title: distutils doesn't add "-Wl," prefix to "-R" on Linux if the C compiler isn't named 'gcc' versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25229> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
