musl-powered rust playground

@ernsteiswuerfel I pushed 1.52.1 and 1.53.0

please always make a backup with quickpkg once you went up one version successfully, and please never ever use +system-llvm, you can end up in horrible and maybe unfixable circular dependency situations.

with 1.53.0 you can compile librsvg-2.52.5, firefox-96.0 and eapi8 ebuilds such as cbindgen, it seems to be a good base for now untill I figured out what to do with patch 0005-Use-static-native-libraries-when-linking-static-exec.patch for rust-1.54.0

the in tree dev-lang/rust-1.58.1 ebuild has a dist useflag, where it seems to be possible to emerge it with a freshly packed stage2 archive: Install dist tarballs (used for bootstrapping) so maybe its possible to use that for getting fresh llvm-13 based stages nativly build

[ernsteiswuerfel]

Thanks! Updating to 1.53 worked flawlessly on ppc64. cbindgen and Firefox ESR are still buildable, did not try firefox-96.0 yet.

librsvg-2.52.5 fails however. librsvg-2.52.5:20220323-134919.log

[stefson]

you can try this fix from alpine: 0001-fixup-system-deps-targets.patch.zip

[ernsteiswuerfel]

The patch worked librsvg-2.52.5 built fine, thanks!

[ernsteiswuerfel]

@stefson Fiddled around with the ppc build a bit. Turned out I needed only this small patch to make it build: https://github.com/void-ppc/void-packages/blob/master/srcpkgs/rust/patches/fix-ppc32.patch

It did not apply on rust-1.49.0::smaeul but this was easy to fix. Bootstrapping from 1.49.0 working fine so far with the patch. 1.50.0 done and 1.51.0 in the works. 🥳 fix-ppc32.patch.zip

[ernsteiswuerfel]

Ok, so btootstrapping up to 1.53.0 worked well with the patch on ppc32. Next I was hoping to build librsvg-2.52.5 on ppc but this failed. librsvg-2.52.5:20220402-222802.log

Building librsvg-2.52.7 on ppc musl on the other hand succeeds. librsvg-2.52.7:20220402-223533.log

[stefson]

I did some research about this and learned that powerpc simply doesn't have AtomicI64 support, neither gnu based nor musl based rustc. Some crates work around it, others don't, but custom targets such as all of our musl based ones need to intervene here manually.

Try this approach please, its the least invasive:

diff --git a/.cargo/config b/.cargo/config
index a94e912..ccf8ea3 100644
--- a/.cargo/config
+++ b/.cargo/config

its against librsvg-2.52.5, please drop into /etc/portage/patches and report back

[ernsteiswuerfel]

With this patch librsvg-2.52.5 built without problems. Thanks!

[stefson]

I stole the idea from here: https://github.com/crossbeam-rs/crossbeam/issues/731 , it might happen again for cargo-c or any other ebuild that uses the crossbeam crates, and the fix would be similar.

An alternative is to export as RUSTFLAG through /etc/portage/make.conf or on a per package based env file in /etc/portage/env/

[stefson]

I pushed rust-1.54.0 for you. please report back with positive and negative feedback.

you will need the updated patch for librsvg-2.52.6: 0001-fixup-system-deps-targets.patch.gz

[stefson]

1.53.0 at work:

[ernsteiswuerfel]

I pushed rust-1.54.0 for you. please report back with positive and negative feedback.

Hunk #1 FAILED at 1299.

You need to take my modified version, the original one would not apply (see my comment above).

[stefson]

I see, the merge window of the underlying change is between 1.55.0 and 1.57.0; before that it has to be backported. It was a blind shot, because I'm a bit ahead of publishing the ebuilds here and the ebuild won't let me src_prepare without a useable system-rust lol

//edit: underlying change is merged in 1.56.1

[ernsteiswuerfel]

Ok, rust-1.54.0 and librsvg-2.52.6 built fine on ppc64. 🥳 ppc coming up next...

[ernsteiswuerfel]

Success on ppc too with rust-1.54.0 and librsvg-2.52.6!

[stefson]

I pushed 1.55.0 and 1.56.1, hopefully I didn't mess up the ppc32 patch again :rofl:

1.56.1 is llvm13 based, with it you can emerge librsvg-2.54.0

please test and report back

[ernsteiswuerfel]

1.56.1 upgrade went flawless on ppc64. It did not build librsvg-2.54.0 however: librsvg-2.54.0:20220406-103703.log

I'll try ppc32 next.

[stefson]

you forgot to forward the patch, its still needed.

[ernsteiswuerfel]

Oops... Yes, with the patch librsvg-2.54.0 builds fine!

Btw. could you add rust-1.48.0 and 1.49.0 from smaeuls overlay to yours? This way interested users could bootstrap up to 1.56.1 without the need of installing 2 overlays. Would be more convenient.

[stefson]

honestly I'm more interested into getting the powerpc issue fixed upstream.

Do you still have the failed build log available? I forgot where you mentioned it for the first time.

[ernsteiswuerfel]

I think you mean this thread: https://github.com/gentoo/musl/pull/366#issuecomment-1052318916

[stefson]

the ppc32 patch only extends the whitelist to include powerpcle-* targets; but you are not on little endian, are you? could be helpfull for me if you shared the output of cpuid with me.

[ernsteiswuerfel]

No, i have all my PPC machines on BE. The Talos II which I booted into the ppc32 G4 partition (to build 1.55.0 and 1.56.1 right now) shows this data:

which is the original patch: https://github.com/rust-lang/rust/commit/283619cf5ca25272b294525273ec42e9c7820edb

the patch used right now merely extends the target.triple to powerpcle, but your system should not take notice of that. I could be wrong though, don't have any hardware to test.

[ernsteiswuerfel]

True. I successfully built 1.56.1 on ppc with the ppc32 patch disabled. I think the versions before still need the (original) patch.

The powerpcle target triple is Void Linux only AFAIK and that's where I got the patch from. They are about to create a ppc32 LE version of their distro. Don't know what's the working state of it however. ppc64 LE is rather common I guess. But ppc64 LE does not seem to need this patch? Don't have any PPC box on LE so I can't tell.

librsvg-2.54.0 builds on ppc32 too, so all good. 😄

[stefson]

@ernsteiswuerfel I pushed 1.57.0 to the overlay, this is enough to build you nice firefox-99.0 and firefox-100.0 beta if you feel like testing them.

[stefson]

1.58.1 at work:

[stefson]

hint: webrtc is horribly broken with the last update in firefox-94.0 on any arch except amd64, arm64 and x86 I believe. Simply pass additional --disable-webrtc

[ernsteiswuerfel]

Meanwhile I upgraded toolchain to musl-1.2.3 and binutils-2.38-r1 (+ gcc-11.2.1_p20220115 as before) on ppc64. And I am on your rust-1.58.1 now. rust-1.57 did not build with binutils-2.38-r1 (see logfile), I needed to use binutils-2.37_p1-r2. rust-1.57.0:20220414-101217.log.gz

Did not build any of the new Firefox versions yet, only ESR.

[stefson]

you need to report that bug to binutils upstream bugtracker at sourceware.org/bugzilla, there are various pullrequests concerning assertion failures of llvm, as well as them being reverted for introducing regressions recently.

[stefson]

@ernsteiswuerfel if you ever get stuck again, here is how to bootstrap yourself a new rustc-stage through cross compile: https://wiki.gentoo.org/wiki/User:Sam/Drafts/Bootstrapping_Rust_cross

[ernsteiswuerfel]

Thanks for the hint! Always good do know as a last resort. 😉

However after mimicking my ppc64-musl settings closely on my ppc32-musl setup and rebuilding world afterwards my issues with binutils-2.38 & rust are gone. I am happily on rust-1.59.0 from your overlay on ppc32 now. 🥳

[stefson]

lovely to see it working, I plan to push out updates once rustc is not recent enough anymore to compile latest stable firefox. If I somehow manage to miss it please ping me here.

[stefson]

@ernsteiswuerfel are you able to compile firefox-103.0.2 with gcc and the musl-powered rust-1.59.0? I'm running into linking errors:

I would not expect to build it on ppc32 anyhow as it's broken on this arch for a long time... Last working Firefox on ppc32 was around FF 49.x or 52.x. or so.

On ppc64 FF 91.x builds fine but I am having trouble with FF 102.x. However ATM I am running rust::smaeul und not yours yet.

Anything specific I should check or try?

[stefson]

beginning with firefox-103 branch, I get linking errors from ld.bfd on armv7a - they are somewhat similar to https://bugs.gentoo.org/866293

other than the broken compile I don't have any issue with 103.0, and none with 102.0

you are welcome to share your logs, I will share mine in the next days when I get enough free cpu time to compile 103.0 again //Edit: I forgot that I posted the actuall error one post above your last one ;)

[stefson]

@ernsteiswuerfel I pushed rust-1.60.0 and rust-1.61.0 to the overlay, firefox-105.0 will need it.

[ernsteiswuerfel]

Sorry for it took me so long, but I was a bit occupied by testing out a ppc llvm bug and another clang bug. 😮‍💨

Tried rust-1.60.0 now (with system-bootstrap) but it didn't work out. Log attached. rust-1.60.0:20221012-130526.log

[stefson]

from the changelog of crossbeam-utils:

# Version 0.8.6

- Re-add `AtomicCell<{i,u}64>::{fetch_add,fetch_sub,fetch_and,fetch_or,fetch_xor}` that were accidentally removed in 0.8.0 on targets that do not support `Atomic{I,U}64`. (#767)
- Re-add `AtomicCell<{i,u}128>::{fetch_add,fetch_sub,fetch_and,fetch_or,fetch_xor}` that were accidentally removed in 0.8.0. (#767)

I believe this is the problem you're facing.

it will make the compile fail with some checksum errors at first, please report the failed log back to me so I can patch the new checksum into the final patch. I can't roll back to rust-1.60.0 anymore.

[ernsteiswuerfel]

Thanks! Here's the new log with your patch. rust-1.60.0:20221012-221717.log

[stefson]

I pushed the supposed fix for 1.60.0 and 1.61.0 for now, please test and report back the results.

[ernsteiswuerfel]

1.60.0 built fine so far and successfully built librsvg.

[stefson]

ok great.

librsvg-2.55.1 will be troublesome since upstream decided to not vendor their crates themselves anymore - this means if one crate fails to compile the whole package will be broken beyond repair. At least it seems to be like that on a quick glance, as its impossible to patch the crates themselves.

Ok, good to know! I built librsvg-2.54.4 as this version is getting stabled on Gentoo.

Aaand rust-1.61.0 finished building too, everything seems ok. Thanks for your efforts!

[stefson]

yeah, its pretty bad as you can't repack the patched crate.

can you imagine to host a repacked librsvg version in the future, on your dev space? its pretty easy to repack, all you have to do is to copy all the unpacked crates into the vendor folder and compress it.

[ernsteiswuerfel]

Not really as I am neither a Gentoo Dev (arch tester only) nor I got dev space. 😉

[stefson]

can you give librsvg-2.55.1 a try on your setups? I'd like to know if it has any additional bugs

[ernsteiswuerfel]

Just gave it a try but did not get far as the AtomicU64 patch from earlier versions did not apply. librsvg-2.55.1:20221017-111808.log
