https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221423 --- Comment #12 from Jan Beich <jbeich@FreeBSD.org> --- (In reply to Walter Schwarzenfeld from comment #10) > Is this still relevant? std::locale test still fails on GCC < 6. As lang/gcc (i.e., g++ symlink) abides by GCC_DEFAULT it's not an issue since bug 219275. $ pkg install gcc48 gcc5 gcc6 gcc7 gcc8 gcc9 $ g++9 -Wl,-rpath=/usr/local/lib/gcc9 test.cpp $ ./a.out $ g++8 -Wl,-rpath=/usr/local/lib/gcc8 test.cpp $ ./a.out $ g++7 -Wl,-rpath=/usr/local/lib/gcc7 test.cpp $ ./a.out $ g++6 -Wl,-rpath=/usr/local/lib/gcc6 test.cpp $ ./a.out $ g++5 -Wl,-rpath=/usr/local/lib/gcc5 test.cpp $./a.out locale::facet::_S_create_c_locale name not valid $ g++48 -Wl,-rpath=/usr/local/lib/gcc48 test.cpp $ ./a.out locale::facet::_S_create_c_locale name not valid $ g++42 test.cpp $ ./a.out locale::facet::_S_create_c_locale name not valid As for ABI mismatch between g++ and libstdc++ when -Wl,-rpath is not passed and more than one lang/gcc* is installed it doesn't seem to crash on FreeBSD 11.3 or later. $ uname -rp 11.2-RELEASE amd64 $ pkg install gcc48 gcc5 gcc6 gcc7 gcc8 gcc9 $ g++9 test.cpp $ ./a.out Abort trap $ ldd ./a.out ./a.out: libstdc++.so.6 => /usr/local/lib/gcc48/libstdc++.so.6 (0x800822000) libm.so.5 => /lib/libm.so.5 (0x800b29000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x800d56000) libc.so.7 => /lib/libc.so.7 (0x800f65000) -- You are receiving this mail because: You are the assignee for the bug.home | help
