I use MCM to build statically linked binaries against muslc built on Alpine Linux.

It said that this commit looks to be the culprit:

looks like just a missing include of stdint.h/cstdint @ #musl

Thanks, I can confirm this fix allowed my builds to complete successfully.

[jhasse]

If you want to avoid having to open such an issue in the future, contribute a GitHub Action that builds with musl :)

[userdocs]

This is what I use to build from master but I use custom build of MCM which have no official releases, hence the range of targets,

https://github.com/userdocs/qbt-ninja-build/blob/main/.github/workflows/alpine_multi-master-matrix-muslcc.yml

I figure this is not an ideal solution to the suggestion unless a source for the toolchains could be agreed upon, maybe here?

https://musl.cc

The other way is qemu/alpine emulation. Not the fastest way but less unique.

I could do this but i'd need to understand implementation would be best suited for the project,

Crossbuilding or emulation, emulation is probably the easier to maintain but longer build times.

[userdocs]

I may have got ahead of myself there.

Would a simple x86_64 workflow suffice for this need?

[jhasse]

yes
