Second attempt at AArch64 Rust

[mati865]

Closes #9046

[jeremyd2019]

started up a fresh vm and started the job, see what happens. https://github.com/msys2-arm/MINGW-packages/actions/runs/3216377518/jobs/5258497279

[jeremyd2019]

Well that's odd, it seems to have failed but there's no logs on the job. On the runner there are some logs left, but it looks like they just stop, rather than seeing any error in particular. Probably have to try it again.

[mati865]

Maybe they are crashing due to lack of memory or something?

[jeremyd2019]

Could be. I might need to fire up a 'cloud' instance. I did get access to Azure free trial, but am "blocked" by a stupid checkbox that says I confirm that I have the right kind of Windows license. I've got an email in to a contact at Microsoft, who is checking with his contacts to see what we can do about that. I'm sure I've done test scenarios in the past that are questionable for licensing, but explicitly checking the box was a step too far 😛

For now, I'm going to try running it again locally. if the whole vm doesn't crash I should at least see what happened. I'm also taking --verbose out of the command, that seemed to make it harder to see what's going on.

Luckily, it seems that editing the PKGBUILD to not rm -rf the build dir and using makepkg -e let it pick up where it seems to have left off, building std crate in stage0 std artifacts (and moved on from that)

I'm also taking --verbose out of the command, that seemed to make it harder to see what's going on.

Yeah, I also remove that flag when working on it because it's too verbose and hardly ever does help if there are issues.

[jeremyd2019]

Seems to be working well, and a lot faster than the cross x86_64 did on the pi. It was installing stage2 rust-docs last I checked. Once this is finished would it be interesting if I try to run check()? Or try to pick some packages to build with it?

[mati865]

Wonderful!

check() could be useful but I expect it to fail.

Building crates might be a bit hard because everything that depends on windows or windows-sys crates in versions older that 0.42 will fail until ecosystem migrates to newer versions or I come up with yet another hack....
You can start with https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-ripgrep/PKGBUILD, this crate doesn't depend on windows* so it might actually work out of the box.

[jeremyd2019]

It's up to installing rust-src now, as I recall that took a long time even on a more powerful machine... Assuming I get a successful build out of this, I'll try to upload it to github somewhere, and then try playing around with it some.

[jeremyd2019]

Build completed successfully in 10:05:08

[jeremyd2019]

I tried running the command from check() but it seemed to be rebuilding from stage0 again 😦 I left it "overnight" but when I checked it in the morning, I could not connect to the VM nor get anything on the 'screen' of the console, so I assume the VM crashed.

[jeremyd2019]

Oops, the host filesystem is full 🤦

[jeremyd2019]

ripgrep makedepends on jq and asciidoctor. jq seems to be building on clangarm64, but asciidoctor depends on ruby which is a can-o-worms (#13115). Hopefully I can comment that out and just not get docs.

[jeremyd2019]

ripgrep package built (with asciidoctor makedepend commented out), and rg --help at least works. Let me know if you want me to test anything else.

[jeremyd2019]

Is this (otherwise) ready to merge?

[mati865]

Scrolled through the changes one more time, I believe it's good to go!
