Eric Dujardin <eric.dujar...@laposte.net> added the comment: I have the same error when building 3.6.4, however not exactly with the same options. Some context first: $ lsb_release -d; lscpu |head -1 Description: Ubuntu 14.04.5 LTS Architecture: x86_64 $ gcc --version gcc (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4
I'm careful to start from a freshly untarred source tree. This configuration builds a working installation: $ ./configure --prefix=$PYTHON --enable-optimizations --enable-shared LDFLAGS="-Wl,-rpath=$PYTHON/lib -Wl,-Bsymbolic-functions -Wl,-z,relro" --with-computed-gotos --with-system-ffi --with-fpectl --with-system-libmpdec $ make profile-opt However, I get the reported error when CFLAGS="-mtune=core-avx2 -march=core-avx2" is added. This set of options works fine without --enable-shared, i.e. this is what I am using for static builds: $ ./configure --prefix=$PYTHON --enable-optimizations LDFLAGS="-Wl,-z,relro" --with-computed-gotos --with-system-ffi --with-fpectl --with-system-libmpdec CFLAGS="-mtune=core-avx2 -march=core-avx2 -Wformat -Werror=format-security" Note, with the following configuration (-mtune without -march), compilation just blocks on Objects/memoryobject.c (ie, gcc never completes): $ ./configure --prefix=$PYTHON --enable-optimizations --enable-shared LDFLAGS="-Wl,-rpath=$PYTHON/lib -Wl,-Bsymbolic-functions -Wl,-z,relro" --with-computed-gotos --with-system-ffi --with-fpectl --with-system-libmpdec CFLAGS="-mtune=core-avx2 -Werror=format-security" $ make profile-opt ---------- nosy: +eric957 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue29712> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
