Description acertig04 2022-12-17 02:26:03 UTC

After playtesting with clang building some targets with crossdev, I found none of them went past stage1. Specifically on aarch64-unknown-linux-gnu, which eventually worked with gcc. Seems like it libcc on /lib but then looks for it in /lib64, which doesnt exist. Attachment contains the stage1 log from crossdev --stable -s4 -t aarch64-unknown-linux-gnu.

After discussing this on IRC there is a possibility this might due to the fix in  https://bugs.gentoo.org/652724#c18 only detecting GCC and not clang as I've run into a similar issue with Musl on MIPS.


I'll highlight the code below:
