Not sure what's going on here yet.

Currently in the process of trying to get a stage3 tarball for catalyst from scratch (CBUILD is aarch64-unknown-linux-gnu) for aarch64-gentoo-linux-musl.

I get pretty far, although I end up being unable to build GCC with the cross-built GCC.

guix seem to have hit the same issue: https://issues.guix.gnu.org/49600. Can't find an upstream report yet.

Errors look like:

Comment 2 Sam James archtester gentoo-dev Security 2021-09-01 02:51:32 UTC
Building gcc 10.3.0 works, however. Note that I'm using gcc 10.3.0 for compilation. Not tried building gcc 11 with gcc 11.
Comment 3 tt_1 2021-10-01 15:46:37 UTC
I never had much luck with mixing up gcc versions between host, target and rootfs. Its propably very time consuming to chase this down, with little benefit. Sorry if my message is not very constructive :)
