Possible to stabilize it ? At least for amd64 ? Will need dev-lang/zig to be stabilized too. Thanks Reproducible: Always
You would also need opinion of the zig maintainer whether that package is ready to be stabilized.
Not yet, maybe it can be considered after https://github.com/gentoo/gentoo/pull/37283 is merged. Is Gentoo Prefix support needed for stabilization? I know that with that eclass regular compilation and cross-compilation works, but I have not patched Zig yet to support working in Gentoo Prefix. It can fail in situation when kibc of host and prefix differ, because of unconditional unprefixed use of /usr/bin/env. More context here: https://github.com/ziglang/zig/issues/14146 . BTW it's probably easier to stabilize dev-lang/zig-bin before dev-lang/zig, it is fully static distribution.
