common/cpu.c:171: error: for each function it appears in.)
common/cpu.c:171: error: expected ';' before 'p_aff'

common/cpu.c:173: warning: implicit declaration of function 'sched_getaffinity'
make: *** [common/cpu.o] Error 1

After making the dirty hack in common/cpu.c:

/* #elif defined(SYS_LINUX)
    unsigned int bit;
    int np;
    cpu_set_t p_aff;
    memset( &p_aff, 0, sizeof(p_aff) );
    sched_getaffinity( 0, sizeof(p_aff), &p_aff );
    for( np = 0, bit = 0; bit < sizeof(p_aff); bit++ )
        np += (((uint8_t *)&p_aff)[bit / 8] >> (bit % 8)) & 1;
    return np; */

it compiles fine.
