Well, I don't understand what is going on.
I downloaded libpfm-3.9.tar.gz compiled on ubunut-8.10 in x86_64
mode. When I run examples_v2.x/self, I get:
$ LIBPFM_DEBUG=1 ./self
sycall base 295
major version 2
minor version 82
pfmlib_common.c (pfm_initialize.154): trying AMD64
pfmlib_common.c (pfm_i
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
Thank you! I will try your configuration.

Ok, I will try to replace the compiler with a different version and to see
what will happen. And could I have your software stack configuration on a
working Nehalem system?
Anyway, I appreciate your help!

Nobody else reported this problem so far. Yet, as I said, I think I
have encoutered
it a while back
No, it doesn't work either. Exactly the same problem. Do you think it is due
to the compiler? I am using gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3
Thank you!

I thought I compile it as the default configuration file you put there which
is "O2"... OK, I am trying to re-compile it with O0.

What is you try to compile libpfm with OPTIM=-O0?

What about you try libpfm/examples_v2.x/self.
Does it crash too?

Hi Stephane,
Do you mean mean the i value in "for(i =0; i pme_count; i++) "
in pfmlib_common.c?
Then it is 0 while the program stops.
Thanks!

It should be right. I "make install" the libpfm by the default config file
and I checked that directory and it shows:
lrwxrwxrwx 1 root root 15 2009-09-23 15:44 libpfm.so ->
libpfm.so.3.9.0
lrwxrwxrwx 1 root root 15 2009-09-23 15:44 libpfm.so.3 ->
libpfm.so.3.9.0
-rwxr-xr-x 1 root
Are you sure the library in /usr/local/lib/libpfm.so.3 corresponds to the
version you have just compiled?

I tracked into the program and found the segmentation fault happened at:
in pfmon.c
pfmon_initialize()->pfm_get_max_event_name_len(&len)
then it jumped into pfmlib_common.c
pfm_get_max_event_name_len (len=0xbffd9460) at pfmlib_common.c:907
907if (PFMLIB_INITIALIZED() == 0)

it's
