LLVM 8.0

[baerbock]

Is there already a LLVM 8 tracking issue? Like #50543

Currently Rust doesn't like that
error: couldn't load codegen backend "/usr/lib64/rustlib/x86_64-unknown-linux-gnu/codegen-backends/librustc_codegen_llvm-llvm.so": "libLLVM-7.so: cannot open shared object file: No such file or directory"

[mqudsi]

You're misunderstanding the error. #50543 was about upgrading rust internally to use llvm 8, for various reasons. The rust you're using was built against llvm7, and you don't have it installed.

@mqudsi Do I need Rust to compile Rust?

[mqudsi]

Yes. Another option: https://www.gnu.org/software/guix/blog/2018/bootstrapping-rust/

Which OS and rustc version?

cc #56849 another issue in the last 24 hours with loading codegen backend, except that fails while looking for /lib64/libgcc_s.so.1. Does it error when running rustc -vV as well?

Can this issue be closed? It's not really clear to me what this is about at this point.

Currently there is not much information to go on, so it deems safe to close. If you continue to run into any issues, baerbock, feel free to let us know!
