Hello, I'm trying to compile paludis ([1]) on my Gentoo PPC/uclibc system, but it fails due to an undefined reference to pselect.
For testing purpose I've taken the example from pselect manpage, which fails the same way as paludis does. The failing file is attached to this mail. Here comes the error: $ make pselect cc pselect.c -o pselect /tmp/ccLqJzkO.o: In function `main': pselect.c:(.text+0x98): undefined reference to `pselect' collect2: ld returned 1 exit status make: *** [pselect] Error 1 Do I have to link to some library, or is this an error in uclibc?

/* FD_ISSET(0, &rfds) will be true. */
else
printf("No data within five seconds.\n");
exit(EXIT_SUCCESS);
