Firefox 85+ on -current fails build

My current slackbuild script no longer works for 85+ - compile fails at:

Anyone have adjustments to slackbuild or patches to assist with this release? My most recent successful build is 84.0.2 - the last slackbuild patch at that time was:

Quote:

# https://bugzilla.mozilla.org/show_bug.cgi?id=1640982
sed -i "s|-Clto$||" config/makefiles/rust.mk

... for a rust-related issue.

(my system is -current 64bit updated to just before the recent mega rebuild)

Thanks in advance.

if you try to build the new version with gcc you may encounter these errors

what I do here is cheat a little and use llvm: I modify the mozilla-firefox.SlackBuild in current like this

and I just built the 86.0 candidate with it.

Thanks for the changes Ponce. I always use clang on Mozilla stuff but added your other changes and the candidate built fine.

Thanks very much @Ponce - I think I've broken something in my slackbuild so would you mind providing the full latest slackbuild you used in the 86 build?

it's the one available in the /sources/xap/mozilla-firefox/ directory of current with just the modifications above applied...

Thanks, I've started with a fresh copy of the source folder and applied the patch. Got the following:

So I've commented nodejs out in the build-deps.sh file (I have a system nodejs) and run build again. Completed this time and I have a 85.0.1 build now.

Thanks for your help

If anyone wants to try a PGO+LTO build (which won't work with gcc anymore, btw), use the lld linker. Gold is pretty borked these days (can't handle this build for me anymore... barfs with internal errors on the final linking of libxul since Firefox 84) and ld.bfd would likely OOM.

ac_add_options --enable-linker=lld

elfhack doesn't fail with lld currently, so no need to --disable-elfhack at this time (I'm saying that because it used to, at times)

Definitely want to use llvm-ar, llvm-nm, llvm-ranlib for a PGO+LTO build now.
