PKGBUILD has been updated. Major changes:

  • Downloads Firefox ESR and localization using the source array. Files are saved for reuse.
  • Saves freshly patched IceCat sources in a tarball for reuse.
  • Saves the PGO profile for reuse.

Notes:

  • Currently requires clang/llvm 17, which has to be built from AUR.
  • Wayland users, consider setting _build_pgo_xvfb=false. This will use xwayland-run for profiling.
  • PGO should work now, but if it doesn't and you're willing to go without, try _build_pgo=false.
  • Running out of RAM? Try adding mk_add_options MOZ_PARALLEL_BUILD=___ around line 300. Pick a value less than number of cores and free RAM in GB. For example, on a system with 8 cores, 64GB total RAM, but only 6 GB free, the value should be set to 4 or 5.
    • If a few people can confirm this is helpful, I will consider adding it as an additional option.
    • Main resource hog seems to be linking libxul.so. Leave a comment if you have a potential solution.

Having problems? Please provide details: processor make and model, number of cores, free -m, full log in pastebin, whether using AUR helper/makepkg/clean chroot, etc.

@Ningen

allocate large swap file like in my previous comment

Not appropriate to change system parameters like that inside of PKGBUILDs.

mk_add_options MOZ_PARALLEL_BUILD=4

Not needed. mach sets an appropriate value based on available cores.

ac_add_options MOZ_PGO=1

Not suitable for PKGBUILDs because doesn't work in clean chroot.

PGO makes building almost 3-5x longer

That is normal. PGO has three stages:

  1. Instrumented build.
  2. Profiling.
  3. Optimized build.

The PKGBUILD has been constructed to save the profile to reduce time for subsequent rebuilds by skipping to the last step.

@xiota Yes I am using that option right now compiling on my more powerful pc, however looking at the memory requirements it's most likely still going to be going over any normal laptop memory + swap space, so in that case I think it's actually better to just leave as ac_add_options --enable-lto=full actually and just allocate large swap file like in my previous comment.

I am going to be trying two different PKGBUILDS to see if I notice any improvements, because currently even on a good pc PGO makes building almost 3-5x longer. Namely, I was browsing the mozilla build docs and found that the option mk_add_options MOZ_PARALLEL_BUILD=4 could be used but isn't in the PKGBUILD, also, they don't really specify much about PGO on the docs so I am going to just try remove a large portion of the build() section replaced with the option ac_add_options MOZ_PGO=1 as they specify on the docs, not sure if it will work though

Tried to build on my laptop with ~30GB of ram and it just failed before compiling toolkit/library/build/libxul.so which were one of the last few components, very annoying. Retrying build with ~50GB ram on a more powerful computer.

@texer22 In the PKGBUILD on line 85 change if [ "${_only-compile}q" = q ]; then to if [ 1 ]; then. I would also not recommend building until someone figures out whether the PGO build really requires a lot of ram or there is an issue somewhere

@figue You're right it seems to be much more resource intensive than before PGO, I can't compile natively with 8GB ram and 8GiB swap space. That said, perhaps the only option is to make a very large swap file and use that temporarily for compile time such as https://files.catbox.moe/56bafh.sh I included this as the first line under prepare() before cd gnuzilla-${_commit}, running it now and will let you know how it goes...

@xiota thank you for your PKGBUILD. I've merged a few things.

@Ningen 115.7.0 pushed

Ningen commented on 2024-02-11 09:14 (UTC)

@figue Ohh I see. Would you mind pushing the PKGBUILD for 115.7.0 anyway and I will see if I can compile?

I have currently tried your PKGBUILD here https://gist.github.com/figue/4a407a15e0eedfc2e88eb5de431b69f7 but there are weird things going on outside of your mentioned issue, so I would like to just try to build the regular way if you can push the updates and investigate
