Stéphane,

I don't know if it is due to a lack of experience compiling perfmon and
pfmon, but I can't make pfmon work properly. First, I compile
libpfm-3.51 in my home directory without any problem. Then, I compile
pfmon-3.5 after modifying PFMROOTDIR in config.mk to make sure it looks
for pflib in my home directory. Regardless it's compiled either
dinamically or statically, I get an error when running pfmon:


./pfmon ../tests/noploop 100<pfmon fatal error @ [23806:23806] 
ip=0x400000000008f440 addr=0x18>

0x4000000000006860 <_start+0x80>
pfmon got a fatal SIGSEGV signal
noploop for 100 seconds


First time I tried, I realised pfmon was looking for libpfm in
/usr/local despite the changes in config.mk. I modified LD_LIBRARY_PATH
and then ldd showed that pfmon was now looking for libpfm in my home
directory. However, it won't work. I don't know if it has something to
do with the installed kernel patch or maybe the kernel version:

uname -a
Linux cn001 2.6.16.53-0.8_SFS2.3_0-default #1 SMP Mon Nov 5 14:15:47 CET 2007 
ia64 ia64 ia64 GNU/Linux

Any idea?
