Compilation fails with musl - ze_util.h: error: RTLD_DEEPBIND was not declared in this scope

[ConiKost]

If level-zero is being compiled on a system with musl (glibc replacement), compilation will fail. You can get full log here: https://bugs.gentoo.org/828775

RTLD_DEEPBIND is required for correct symbol resolution in L0 drivers that have L0 APIs in global namespace.

Does musl have an alternative way to enforce RTLD_DEEPBIND functionality?

[ConiKost]

It looks like, that RTLD_DEEPBIND isn't supported at all in musl. So I guess, there is no way to support musl in this case?

[ConiKost]

Yep, it does not. Closing here, as you say, it's a must, so we can't do anything here.
