Description topological-automata 2023-11-10 19:46:39 UTC
tried to build firefox on my llvm+musl system, but it does not compile, spitting out this error:

x86_64-gentoo-linux-musl-ld.lld: error: unknown argument '--real-linker'
I have no clue what else to write, if you need more context I will provide it presto!
attached are the build.log and emerge --info

here's the actual build.log:
I had to use a github gist because it was too big and compression did not help

This came from #gentoo. A bit extra info we collected.

Shortly before the failing call `build/unix/elfhack/x86_64-gentoo-linux-musl-ld.lld` was build.

The failing call contains:
> -Wl,--real-linker,/usr/bin/x86_64-gentoo-linux-musl-ld.lld  
> -fuse-ld=lld
Set in the configure phase is:
> --with-toolchain-prefix=x86_64-gentoo-linux-musl-

From this we had the user run
> # /var/tmp/notmpfs/portage/www-client/firefox-119.0.1/work/firefox_build/build/unix/elfhack/x86_64-gentoo-linux-musl-ld.lld --real-linker,/usr/bin/x86_64-gentoo-linux-musl-ld.lld
> could not determine output file 
> 
> # /usr/bin/x86_64-gentoo-linux-musl-ld.lld --real-linker,/usr/bin/x86_64-gentoo-linux-musl-ld.lld 
> /usr/bin says x86_64-gentoo-linux-musl-ld.lld: error: unknown argument '--real-linker,/usr/bin/x86_64-gentoo-linux-musl-ld.lld'

Which suggests build/unix/elfhack/x86_64-gentoo-linux-musl-ld.lld is never called and instead the system ld.lld is used, maybe due to the toolchain-prefix.

We are waiting on a call with LDFLAGS="-Wl,-O1 -Wl,--as-needed -v" to confirm.

hey sorry for the delayed response, but even though i've CCed me, and in my settings I have all kind of emails enabled, i do not get emails when someone comments. I invoke your mercy!
https://gist.github.com/formula-spectre/2312507bbb6895408a8c4fd85faafae9
this is the build.log with `LDFLAGS="-Wl,-O1 -Wl,--as-needed -v"`
what I did was:
```
export LDFLAGS="-Wl,-O1 -Wl,--as-needed -v"
emerge firefox
```
hope I did the right thing! and again, sorry! i'll try to get the email thing fixed asap. OT but is there someone I can contact for this?
