Actually, I had seen before some (lots of) mails (many from you) that recommands the use of the syscall() interface, but I mis-understood the message... The problem is that I got some problems to find documentation about this interface and made a mix between the kernel and the glibc interfaces. (I finally found some in glibc/manual/libc.info-43 ) I can see clearly now. (Thanks for help) So, as I found how to compile my program, I just send here the way I used the interface, just in case someone would need it. (even, if it's not the purpose of that mail-list). *************************************** #ifndef __NR_sched_setaffinity #ifndef _AFFINITY_H #define _AFFINITY_H #if defined(__ia64__) #define __NR_sched_setaffinity 1231 #define __NR_sched_getaffinity 1232 #endif #define sched_setaffinity(arg1, arg2, arg3) syscall(__NR_sched_setaffinity, arg1, arg2, arg3) #define sched_getaffinity(arg1, arg2, arg3) syscall(__NR_sched_getaffinity, arg1, arg2, arg3) #endif /* __NR_sched_setaffinity */ #endif /* _AFFINITY_H */ *************************************** (...and then just use directly sched_setaffinity in your program !)
