Well, we need to apply the patch below and make tools/lib/str_error_r.c
live in a library that libbpf and perf is linked to.
We have tools/lib/api/ that I think we should make libbpf link against
it, so perf would as well, and even when perf is not linked with libbpf,
those symbols would be available.
The patch below, as-is, is enough for tools/perf/, as it already
statically links with libapi, but we need to do it properly as a library
as stated above.
I'm a bit busy right now, so may take me a bit more time, help in having
libapi used by libbpf would be welcome.
While looking at this I noticed that we should get
tools/perf/check_headers.sh and move it outside perf so that libbpf can
use that mechanism instead of the old ad-hoc series of diffs in its
Makefile, that Jiri forgot to convert to check_headers.
For reference, this is how it looks like now, the builds that take more
time (second column, in seconds, i5 + NVMe) is because it builds with
both gcc and clang, with and without libelf. ClearLinux is failing for
an unrelated problem, its a recent container, also the
ubuntu:18.04-x-i686 cross build is another unrelated problem, something
related to atomics.
Only the alpine (musl libc) are regressions due to the strerror_r
oddity.
