Don Lewis <truckman@FreeBSD.org> has reassigned Bugzilla Automation <bugzilla@FreeBSD.org>'s request for maintainer-feedback to gnome@FreeBSD.org: Bug 199435: [patch] convert lang/gjs to USES=compiler:c++11-lib https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199435 --- Description --- Created attachment 155578 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=155578&action=edit patch to convert gjs to USES=compiler:c++11-lib On FreeBSD 8 and 9, USES=compiler:c11 causes gjs to be built with clang and linked the old version of libstdc++ in base. The x11-fm/sushi port links to both gjs and webkit-gtk3. On FreeBSD 8 and 9, webkit-gdk3 must now be compiled with gcc48 from ports and linked to the version of libstdc++ from ports. sushi itself only appears to contain C code and doesn't require a c++ library. When it is linked, the linker choses libstdc++ based on the order of the shared libraries, and ends up linking to libstdc++ from base. This causes the build to fail with a link error because the base version of libstdc++ does not support the newer c++ ABI version required by webkit-gtk3. Even if the sushi port is hacked to link to the newer libstdc++, the application segfaults inside a deeply nested series of libmozjs and libgjs function calls. See <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=196078>; for more detail. Changing spidermonkey24 and gjs to USES=compiler:c++11-lib, which causes them to be built with gcc48 and linked to its bundled libstdc++, allows the un-modified sushi port to successfully build, and not segfault when run.
