with reference to other email thread on perf build failure on Linus mainline
https://lore.kernel.org/bpf/[email protected]/T/
I see perf build failures on stable-rc 5.18 .. 5.4 with this error [1]
and also noticed on today's linus mainline tree.
Reported-by: Linux Kernel Functional Testing <[email protected]>
steps to reproduce:
--------------------
tuxmake --runtime podman \
--target-arch x86_64 \
--toolchain gcc-11 \
--kconfig
https://builds.tuxbuild.com/2C7oWWWYOYGFtqq4SWX1yG4a2Ne/config \
debugkernel headers kernel modules perf
Error log:
-----------

This include is guarded by:
#if defined(HAVE_LIBBFD_SUPPORT) && defined(HAVE_LIBBPF_SUPPORT)
and from the header path in the failure you are getting an installed
version of libbfd from /usr/include. Using libbfd (GPLv3) with perf
(GPLv2) is becoming an under tested combination due to:
https://www.gnu.org/licenses/gpl-faq.en.html#v2v3Compatibility
Add the make flag NO_LIBBFD=1 to test without libbfd, which will most
accurately match what distributions build.
Testing on my own machine with libbfd version 2.38 didn't show any failures.
Thanks,
Ian
