Subject: compile error due to relocation problems in tools/bpf/resolve_btfids//libbpf/libbpf.a(libbpf-in.o)
Date: Wed, 8 Feb 2023 09:18:31 +0100	[thread overview]
Message-ID: <f7922132-6645-6316-5675-0ece4197bfff@leemhuis.info> (raw)

Hi! My daily linux-next builds for Fedora 36, 37 and 38 failed due to a
compile error today. I lack time to investigate this properly currently
(sorry!), but wanted to report it at least briefly nevertheless.

See below for the error log. I noticed there where changes from Jiri
("tools/resolve_btfids: Compile resolve_btfids as host program") and Ian
("tools/resolve_btfids: Tidy HOST_OVERRIDES") merged yesterday that
touch the code in question, which made me wonder if they cause this. But
maybe my spec file (it's based on the one from Fedora rawhide's kernel)
is doing something it shouldn't do.

Here are the build errors:

On x86_64:
