Re: [PATCH dwarves v3] libbpf: allow to use packaged version

[Dominique Martinet <asmadeus@codewreck.org>]

Hi,

I see this commit has been reverted just before the 1.20 release in Feb:
---
Revert "libbpf: allow to use packaged version"

This reverts commit 82749180b23d3c9c060108bc290ae26507fc324e.

Getting in the way of releasing 1.20, breaking the build of a dwarves
rpm when a libbpf package is installed in a fedora 33 system:

In file included from /home/acme/rpmbuild/BUILD/dwarves-1.20/strings.c:7:
/home/acme/rpmbuild/BUILD/dwarves-1.20/pahole_strings.h:9:10: fatal error: bpf/btf.h: No such file or directory
    9 | #include <bpf/btf.h>
      |          ^~~~~~~~~~~

I can understand reverting due to other pressure to get a release out
but most distros (including fedora) frown upon vendoring code so I think
it would be good to have back ultimately.

Did you or someone else (Luca?) ever take the time to look at it?

I don't see what would be so different with fedora to make this
unfixable, I'd be happy taking a look if nobody has so far.
Would you take the patch back in if I somehow fix rpmbuild with a libbpf
package installed on fedora33?


Thanks,
