Hi
What is the distro you are using?
I observed the same issue on s390 but this was fixed for fedora33 somehow.
The error just went away after a dnf update....
[root@m35lp76 perf]# cat /etc/fedora-release
Fedora release 33 (Thirty Three)
[root@m35lp76 perf]# ./perf test -F 68
68: PE file support : Ok
[root@m35lp76 perf]#
However on my fedora32 machine it still fails:
[root@t35lp46 perf]# cat /etc/fedora-release
Fedora release 32 (Thirty Two)
[root@t35lp46 perf]# ./perf test -F 68
68: PE file support : FAILED!
[root@t35lp46 perf]#
Note that I am running the same kernel on both machines: linux 5.10.0rc7 downloaded
this morning.
