The man page (for the glibc version) says you have to link with -lrt. I don't see you doing that. Do you have to? Does uclibc have such a thing and does it do shm_open? I guess it must or the header files would have failed yoiur earlier compile already. -- Len Sorensen _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
