libm alternative in ports
hi there, does anybody if there's an alternative for libm in the ports dir? i need it, because the newest snapshots of mplayer require log2() and log2f(), which the base libm doesn't support. cheers. alex -- a13x ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
