Hi folks,
I'm seeing errors building perf with gcc 10 on the linux-5.4.y branch.
The linker fails as the traceid_list symbol is defined in multiple
compilation units. It looks like commit
168200b6d6ea0cb5765943ec5da5b8149701f36a ("perf cs-etm: Move
definition of 'traceid_list' global variable from header file") was
added to master to fix this but it's not been backported yet.
Cherry-picking this commit locally fixed my build issues.
Looking at the Fixes tag in that commit, this should probably go into
every stable branch from 4.16.y onwards which is still maintained.
See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=168200b6d6ea0cb5765943ec5da5b8149701f36a
Let me know if you need more info.
Thanks,
