Default Re: linux library needed for pthread_setaffinity_np

Your libc appears to be missing NPTL bits

This is from glibc-2.7 (which is NPTL only):
# nm /lib/ | grep setaffinity
0000e0c0 t __pthread_attr_setaffinity_new
0000e1c0 t __pthread_attr_setaffinity_old
0000ded0 t __pthread_setaffinity_new
0000df80 t __pthread_setaffinity_old
0000e0c0 T pthread_attr_setaffinity_np@@GLIBC_2.3.4
0000e1c0 T pthread_attr_setaffinity_np@GLIBC_2.3.3
0000ded0 T pthread_setaffinity_np@@GLIBC_2.3.4
0000df80 T pthread_setaffinity_np@GLIBC_2.3.3

Also, maybe it works with
since I'm told pthread_setaffinity_np() is a wrapper around
the sched_setaffinity() call (you know the "static inline" kind of wrapper ;-) )
