For now on, until we figure out a way of building the JIT with pre-built stencils, we disable the JIT on RHEL to avoid a dependency on a specific LLVM+clang version. https://discuss.python.org/t/building-the-jit-with-pre-built-stencils/91838 https://src.fedoraproject.org/rpms/python3.14/pull-request/40 https://github.com/fedora-eln/eln/issues/207 ---------- This was cherry-picked from https://src.fedoraproject.org/rpms/python3.14/c/ef2d703504cf0039fe5dc82e21e20053cc827c10 for https://github.com/fedora-eln/eln/issues/258#issuecomment-3085727051 With one difference: We build this package on EPEL and we have clang18 there.
