The Makefile specifies GCC and its FreeBSD 8.0. I don't believe clang was in that soon, but I may be wrong. How can I check that? Where is clang? I have installed 9.0 on another system but haven't had time to try that out yet. _______________________________________________ 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"
