[Jonas via Bug reports for GNU Guix]

Hi! Compiling any Rust projects with cargo/rustc gives me:

librt has been integrated into libc since glibc 2.34.

gcc-toolchain:static should provide an empty library to satisfy the
linker:
--8<---------------cut here---------------start------------->8---
$ guix shell gcc-toolchain:static -- sh -c 'ls $GUIX_ENVIRONMENT/lib/librt*'
/gnu/store/8fv6xh7nyyb4hsi7b7p2s2ihpsj0lvs9-profile/lib/librt.a
--8<---------------cut here---------------end--------------->8---

Thanks

bug#65461: Cannot compile any Rust projects

[brian via Bug reports for GNU Guix]

I'd like to propose that the ‘out’ output of gcc-toolchain include the
stub rt, pthread, and dl stub static libraries. This problem comes up on
a very regular basis, and I can think of no reason not to have the
compatibility shims made available.

They contain no code, as they only exist to satisfy linker command
lines, so they're not relevant for grafting purposes. The workaround of
including the static toolchain means that every static library, not just
the empty stubs, is made availible for linking, which is, IMHO, strictly
worse than putting empty .a files into the default output.

WDYT?

Grepping "!<arch>" in gcc-toolchain:static gives me libanl.a, libdl.a,
libpthread.a, librt.a and libutil.a.  Currently only librt.a is not
present in gcc-toolchain:out, so the proposal is really reasonable for
me.

Cc-ing Josselin since they have sent a patch to #63258.

Hi Josselin, what's the current state of the patch?  Can you resend it
to guix-patches to trigger the build process?


Thanks

Huh, completely forgot about this.  The patch should still be ready, and
I don't expect it to cause any problems.  I can have a look and maybe
merge this afternoon.

Pushed as 6c447ababfb11581a75cff8281e96f701e216692.

A sample hello world should now build with cargo with `guix shell -C
rust rust-cargo gcc-toolchain`.  This is a workaround until we add the
librt.a to the gcc package proper.

Please make sure you add simple reproducers to your bug reports so that
people can check that the bug does get resolved by proposed patches.  I
can't reproduce this with a simple `rustc hello.rs` where `hello.rs` is
the simplest hello world I could find.

I can still reproduce this with:

guix shell —container rust rust-cargo
cargo new hello
cd hello
cargo build

If you add 'gcc-toolchain' in the container ('guix shell --container
rust rust-cargo gcc-toolchain'), it now works, using my recent Guix
9f4b6bc.

Closing, thanks to Josselin for the fix!
