Currently firefox 45.0.1 does not build for arm64, however with a few patches from upstream (and one that, afaik is not sent upstream yet,) it builds and runs with dbus ffmpeg gmp-autoupdate gstreamer hwaccel jemalloc3 jit startup-notification system-jpeg system-libvpx useflags set. The 4 patches that I apply, I nicked from Debian. https://anonscm.debian.org/cgit/pkg-mozilla/iceweasel.git/tree/debian/patches/fixes/Bug-1250403-Part-1.-Define-ARCH_CPU_ARM64-instead-of.patch https://anonscm.debian.org/cgit/pkg-mozilla/iceweasel.git/tree/debian/patches/fixes/Bug-1250403-Part-2.-Import-crbug-354405-for-aarch64..patch https://anonscm.debian.org/cgit/pkg-mozilla/iceweasel.git/tree/debian/patches/fixes/Bug-1252699-Set-WEBRTC_DETECT_ARM_NEON-when-optional.patch https://anonscm.debian.org/cgit/pkg-mozilla/iceweasel.git/tree/debian/patches/fixes/Bug-1257888-Link-chromium-mutex-based-atomics-implem.patch And then the 5th is to NOT use static sizes in jemalloc, which is based on https://anonscm.debian.org/cgit/pkg-mozilla/iceweasel.git/tree/debian/patches/porting/Make-powerpc-not-use-static-page-sizes-in-mozjemallo.patch but adds in !defined(__aarch64__) to it. Otherwise Firefox will just segfault on an arm64 box that does not have 64k page sizes. Lastly, I'm not entirely sure if this is an issue in the arm64 build, but I had firefox 38.7.1 installed and was getting the following during the install step: Executing /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/ff/dist/bin/xpcshell -g /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/ff/dist/bin/ -a /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/ff/dist/bin/ -f /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/toolkit/mozapps/installer/precompile_cache.js -e precompile_startupcache("resource://gre/"); /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/ff/dist/bin/xpcshell: /usr/lib64/firefox/libxul.so: version `xul45' not found (required by /var/tmp/portage/www-client/firefox-45.0.1/work/firefox-45.0.1/ff/dist/bin/xpcshell) Once I removed firefox 38.7.1, it seemed to run correctly;
Thanks for the patches! I'll try and review these within the next 24h.
(In reply to Ian Stakenvicius from comment #1) > Thanks for the patches! I'll try and review these within the next 24h. Patches are sane and can be added without delay.
The patches are sane, however, there's still another issue somewhere in JIT :(
I expect https://bugzilla.mozilla.org/show_bug.cgi?id=972710 is somewhat relevant here.
There has been a few versions since this bug was posted, please check newer versions and let me know if more patches are needed
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
