Created attachment 488556 [details] emerge --info I was trying to compile firefox-55.0 - with the following USE flags: bindist, dbus, gmp-autoupdate, hwaccel, jemalloc, startup-notification - using clang (and lld) 4.0.1. Compilation halted with the following error: /var/tmp/portage/www-client/firefox-55.0/work/firefox-55.0/security/sandbox/linux/SandboxOpenedFiles.cpp:47:47: error: use of undeclared identifier 'errno' SANDBOX_LOG_ERROR("dup: %s", strerror(errno)); This error did not occur with firefox-45.0.1, that compiled just fine with clanf and lld. Here is the full build.log: http://paste.ubuntu.com/25287833/

Created attachment 488734 [details, diff] Add errno.h to list of includes SandboxOpenedFiles.cpp, which was not present in firefox-54.0.1, was missing the following line: #include <errno.h>
Please test with firefox-56.0_beta9 from mozilla overlay. If you can still reproduce please feel free to reopen.
Is there a difference between the www-client/firefox-57.0 ebuilds in the portage tree and the mozilla overlay? I build firefox-58 *without* the mozilla overlay and my suggested patch was still needed to allow it to build with clang-5.0.0.
hmm, I had a quick look at the file you had to patch, and the errno.h is now included. Could you try again with 59.0, as it will hit the tree in the next time? Wanted to test it with arm, but there are problems with src_configure, before even starting to compile.
I have the same error with thunderbird-60.2.1 and the patch fixes this issue
