Subject: "Test object code reading" failing, debug messages don't help
Date: Mon, 11 Nov 2013 16:51:17 -0300 [thread overview]
Message-ID: <20131111195117.GI27198@ghostprotocols.net> (raw)
Hi Adrian,
I have perf test failing here:
[root@ssdandy ~]# perf test 21
21: Test object code reading : FAILED!
[root@ssdandy ~]#
Try it with -v, but all messages, except for that elf header, which I
assume is for a previous entry that is not suitable and should not be
considered, seems to say all is well, except that the test fails :-\
[root@ssdandy ~]# perf test -v 21
21: Test object code reading :
--- start ---
Looking at the vmlinux_path (6 entries long)
symsrc__init: cannot get elf header.

Can you try this on acme/perf/core? And improve the debug messages, if
possible?
