Builds broken in Alpine Linux 3.19 (x86_64) with rustc 1.70

[jesusmgg]

I usually run Helix built from source and building in Alpine 3.18 used to work as expected.

I'm building following the instructions with: cargo install --path helix-term --locked.

Since I upgraded to Alpine 3.19 (musl libc) builds are broken with linking errors as shown below:

error: could not compile `libc` (build script) due to previous error
error: could not compile `rustix` (build script) due to previous error
error: linking with `cc` failed: exit status: 1

Using rustc 1.75 the build works without issues.

It looks like the libc dependency is what's failing the build. You can try compiling libc to see if this is reproducible outside of the Helix build: https://github.com/rust-lang/libc

Those liking errors are in std. Every functional modern Linux system should have stat64. Whatever is going here is likely some sysroot/target issue. Since it's working with rust 1.75 I suspect it's already been fixed by the rust project

[jesusmgg]

Yes, reading through the rust project issue tracker this is the case. I'll close this then and just wait until you are ready to update the toolchain and the problem fixes itself.
