I have seen this before and it was du to some mismatch between pfmon and libpfm. If you did make and make install in libpfm without changing the config.mk, then you get libpfm.so in /usr/local/lib. Similarly, if you typed make and make install with pfmon, you have it in /usr/local/bin. Yet it seems for your output above that you find it in /usr/bin. Are you using the right pfmon? Simply try running pfmon from the directory you compiled it in. -- -Stephane _______________________________________________ perfmon mailing list [email protected] http://www.hpl.hp.com/hosted/linux/mail-archives/perfmon/
