Bug 811294 – sys-devel/gcc-11.2.0: fails to cross compile for musl (error: there are no arguments to ‘__is_nothrow_constructible’ that depend on a template parameter, so a declaration of ‘__is_nothrow_constructible’ must be available [-fpermissive])

• Status: CONFIRMED
• Product: Gentoo Linux

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:

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 :)

Had the same issue compiling for arm5. Switching to 11.2 cross-compiler allowed me to get further but failed at some later point with errors like these:

I think you're right tbh.

ah, bug 803371

[Comment 8 Gordon Bos 2021-11-10 13:37:52 UTC]

Confirmed

That does result in a successful build, but obviously also implies a double work-around for the original issue.
