This is minor, but it looks like the PKGBUILD is missing this dependency python-yaml. @rnestler Would you mind adding python-yaml to makedepends?

Update: Thanks for updating! It was quick.

Ah, that will probably be hard to support, since currently Rust support in the Linux kernel needs exact versions of the Rust compiler and the bindgen tool.

According to https://rust-for-linux.com/rust-version-policy this should change with the 6.11 kernel, so that we could use the packaged versions of rustc and the compiler.

Btw. if you want to propose changes to the PKGBUILD you can create a PR in https://github.com/rnestler/archpkg-linux-rust.

Ah, I am building in a clean chroot

Ah, that will probably be hard to support, since currently Rust support in the Linux kernel needs exact versions of the Rust compiler and the bindgen tool.

But I guess you'd need to add ~/.cargo/bin to the PATH, since that's where cargo will install it. (/build/.cargo/bin/ in your case judging from the output).

Ah, I am building in a clean chroot, not on the live filesystem. I added rustup default stable to the prepare function but encountered another error:

@graysky Is rustup otherwise working for you? Can you try to execute rustup show in your home directory and then in the linux-rust PKBGUILD directory?

In the PKGBUILD directory it should show something similar to

active toolchain
----------------

1.76.0-x86_64-unknown-linux-gnu (overridden by '~/projects/archpkg/linux-rust/rust-toolchain')
rustc 1.76.0 (07dca489a 2024-02-04)

Otherwise try to run the command the error suggests: rustup default stable.

I get this failure, any advice?

@user20159 Could you get it to build? I added a check to the PKGBUILD now which should verify that Rust support is really available.

@user20159 Judging from the build logs Rust support gets disabled during the config step:

-CONFIG_RUST_IS_AVAILABLE=y

It looks like something is missing on your system. Maybe rustup isn't configured correctly or something?

Can you do

cd src/linux-6.9.7/
make LLVM=1 rustavailable

I tried both. It does not matter whether I use an AUR helper or run git clone + makepkg -sri manually, the same error occurs in both cases, also with the new version. See the full build log here: https://codeberg.org/LukeLR/gists/src/branch/main/rust-linux-build.log

Hi, building the linux-rust-headers fails for me with the scripts/target.json missing. Is this a known issue, or am I doing something wrong?

It's not a known issue. The file should be there. Did you build the packages manually with makepkg after git clone or with a helper like yay?
