Hi Stephane,
I installed a Ubuntu 8.10 including gcc-4.3.2, but I got the same problem,
whatever with O2 or O0 compilation. But the 8.10 is for 32bit version. Will
be this the problem?
And I trace deeper into the program "self" in example-v2.x in libpfm3.9
folder after I make install it. I got sth below, can you see any clue?
Thanks!
Qingyuan
