Arch Linux User Repository

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.

since there is no simple "heads up" or "thumbs up" to your reply, @seo.disparate, another comment: Your patch works well for me. Could compile it, works, writing this wir 102.12.0.

General remark: since upstream does not seem to be a big community: where is the difference to LibreWolf. Can't the two projects be merged? Or can icecat at least a lot easier and more modern be derived from LibreWolf instead from firefox?

I know, almost always posing these questions shows that the one asking it does not understand the history or the motivation/goal, the problems or the work involved. Nevertheless, from the user perspective I am happy with icecat, but I could be happier with librewolf in some occations... I'll try it at least.

Anyway: Cheers to you, @figue and @seo.disparate !

So I figured out a patch that fixes the build of mp4parse that only touches two lines (based on what exists in the current version of mp4parse):

mp4parse_macro_mul.patch
--- a/output/icecat-102.12.0/third_party/rust/mp4parse/src/lib.rs
+++ b/output/icecat-102.12.0/third_party/rust/mp4parse/src/lib.rs
@@ -3184,8 +3184,8 @@
             type Output = $output;

             fn mul(self, rhs: $rhs) -> Self::Output {
-                static_assertions::const_assert!(<$output>::MAX <= <$inner>::MAX as u64);
-                static_assertions::const_assert!(<$lhs>::MAX * <$rhs>::MAX <= <$output>::MAX);
+                static_assertions::const_assert!(<$output as UpperBounded>::MAX <= <$inner>::MAX as u64);
+                static_assertions::const_assert!(<$lhs as UpperBounded>::MAX * <$rhs as UpperBounded>::MAX <= <$output as UpperBounded>::MAX);

                 let lhs: $inner = self.get().into();
                 let rhs: $inner = rhs.get().into();

I also needed to change the checksum for mp4parse/src/lib.rs, as otherwise the build would fail complaining about the changed source. Thus, the entries in the PKGBUILD should look like:

...
# Produce IceCat sources
bash makeicecat

patch -p1 < "$srcdir/mp4parse_macro_mul.patch"
sed -e 's|src/lib.rs":"73114a5c28472e77082ad259113ffafb418ed602c1741f26da3e10278b0bf93e|src/lib.rs":"bded10689ddd8fd3fcb4ab01be1ecf3642691d68c3651fc4b00f3ccba67fc7cd|' -i output/icecat-102.12.0/third_party/rust/mp4parse/.cargo-checksum.json

cd output/icecat-${pkgver}
...

Naturally, one will need to add the patch to the array of SOURCES for the PKGBUILD.

I did some digging on the compile issue, and it turns out that Rust 1.70 seems to break the build, such that the code needed to be updated.

https://github.com/mozilla/mp4parse-rust/issues/406
https://github.com/mozilla/mp4parse-rust/issues/387

Looking at the error log, the build uses commit 3bfc47d9a571d0842676043ba60716318e946c06 of mp4parse which was merged in late 2021. So the fix is either to downgrade Rust, or patch the source to use a more recent version of mp4parse, or get upstream to not use the old version of mp4parse.

EDIT: I did more digging and it looks like mp4parse (and mp4parse_capi) is bundled in the firefox esr tarball with sources looking identical to commit 3bfc47d9a571d0842676043ba60716318e946c06 . I think Mozilla may have to change the ESR version to use a newer mp4parse version (assuming there is no API breaking changes)...

EDIT: I think theoretically one could patch the source with the source used in the latest version: https://github.com/mozilla/mp4parse-rust/blob/b363e1362726450bac1a4f81ef0d7a12dc51a86e/mp4parse/src/lib.rs#L3486-L3580

@AgentLoneStar007 it's weird because python-jsonschema is a makedepend. Can you try removing all build directory cache and try again?

Getting this error upon attempting to install: ==> Extracting sources... -> Extracting gnuzilla-5a1894fc966840dc242110ec0459471c637a4675.tar.gz with bsdtar ==> Starting prepare()...

@earlybird what do you mean? The script downloads firefox sources from mozilla.org... Can you retry? It should be ok.
