The libpfm has knowledge of syscall number for 2.6.24 and up. Older kernels will likely need adjustments in pfmlib_os_linux.c. This may be your problem, so let's check that first.
You need to make sure that the pfm_create_context syscall number matches the one used in the kernel. On x86-64, it is in include/asm-x86_64/unistd.h. If not then add a case to the corresponding switch statement in pfmlib_os_linux.c for your arch. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ perfmon2-devel mailing list perfmon2-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/perfmon2-devel
