Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-gecko (Nobody) <gecko@FreeBSD.org> for maintainer-feedback: Bug 255953: www/firefox-esr: Fix compile error with clang/libc++ 12 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255953 --- Description --- During an exp-run for llvm 12 (see bug 255570), it turned out that www/firefox-esr does not build with clang 12.0.0 [1]: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/firefox-78.10.1/media/webrtc/trunk/= webr tc/modules/audio_processing/beamformer/covariance_matrix_generator.cc:13: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/firefox-78.10.1/media/webrtc/trunk/= webr tc/modules/audio_processing/beamformer/covariance_matrix_generator.h:14: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/firefox-78.10.1/media/webrtc/trunk/= webr tc/modules/audio_processing/beamformer/complex_matrix.h:14: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/system_wrappers/complex= :3: In file included from /usr/include/c++/v1/complex:236: In file included from /usr/include/c++/v1/stdexcept:46: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/system_wrappers/excepti= on:3 : In file included from /usr/include/c++/v1/exception:81: In file included from /usr/include/c++/v1/__memory/base.h:14: In file included from /usr/include/c++/v1/__debug:14: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/stl_wrappers/iosfwd:58: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/include/mozilla/mozallo= c.h: 31: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/stl_wrappers/new:52: In file included from /wrkdirs/usr/ports/www/firefox-esr/work/.build/dist/system_wrappers/new:3: /usr/include/c++/v1/new:127:14: error: expected class name : public exception ^ 1 error generated. This is caused by firefox doing a lot of complex and fragile juggling with system headers, and was reported upstream as <https://bugzilla.mozilla.org/show_bug.cgi?id=3D1694575>, then fixed via <https://hg.mozilla.org/mozilla-central/rev/f875a4ffd653>.=20 Hopefully the next esr drop will have this fix included, but for now I prop= ose the attached patch.
