So trying to get build-test working on my Debian derived distro is a
PITA with broken feature detection for options I don't normally use.
I'll try to fix this.
In any case I think I've spotted what is really happening here and it
isn't a failure but a feature :-D The build is specifying
LIBBPF_DYNAMIC=1 which means you get the libbpf headers from
/usr/include. I think the build is trying to do this on a system with
an old libbpf and hence getting the failures above. Previously, even
though we wanted the dynamic headers we still had a -I, this time for
the install_headers version. Now you really are using the system
version and it is broken. This means a few things:
- the libbpf feature test should fail if code like above is going to fail,
- we may want to contemplate supporting older libbpfs (I'd rather not),
- does build-test have a way to skip known issues like this?
Thanks,
Ian
