Neither libmm nor libglib are a part of Glibc, so I'm not sure why you're trying to use them. To get an idea of what a library does, it may be helpful to: rpm -qif /path/to/lib.so I believe that the shm_* functions are in -lrt Also, I have no idea why the man page for shm_* doesn't just *say* that.

That should have been there by default, was it not? -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
