I meant the patch needs to be updated so it either adds these files to EXTRA_DIST (ie. the tarball) or the maintainer-check-extra-dist rule is fixed to ignore them.

Unfortunately those are generated. libnbd supports only Linux, FreeBSD and OpenBSD. It probably would work on MacOS but I haven't tried it. We do support clang on the supported platforms, but because we don't use CI it's not tested very often so I don't know if it works right now.

I'm not sure to what extent we want to use --enable-gcc-warnings on the non-Linux platforms. What does libvirt do here? Do they aim to have GCC warnings clean even on non-Linux?

If ‘./configure --with-libxml2’ is used then it's a bug if libxml2 is not present. But libxml2 is an optional dependency so if they didn't specify ‘--with-libxml2’ and libxml2 is not available it should work. So yes it's a bug. > Anyway, I updated some details and ran it again: > > https://gitlab.com/nertpinx/libnbd/-/pipelines/283351379 > > Let's see what's going to pop up next. golang seems to be failing hard there :-( Looks it fails with libnbd is not already installed (which is a bug). I'll see if I can fix that one.
