Subject: [PATCH bpf-next] bpf: Document the pahole release info related to libbpf in bpf_devel_QA.rst
Date: Fri, 23 Apr 2021 09:23:30 +0800 [thread overview]
Message-ID: <1619141010-12521-1-git-send-email-yangtiezhu@loongson.cn> (raw)
pahole starts to use libbpf definitions and APIs since v1.13 after the
commit 21507cd3e97b ("pahole: add libbpf as submodule under lib/bpf").
It works well with the git repository because the libbpf submodule will
use "git submodule update --init --recursive" to update.
Unfortunately, the default github release source code does not contain
libbpf submodule source code and this will cause build issues, the tarball
from https://git.kernel.org/pub/scm/devel/pahole/pahole.git/ is same with
github, you can get the source tarball with corresponding libbpf submodule
codes from
https://fedorapeople.org/~acme/dwarves
This change documents the above issues to give more information so that
we can get the tarball from the right place, early discussion is here:

Some distros have pahole version 1.16 packaged already, e.g.
Fedora, Gentoo.
