I have met this problem before. WITH_CTF on world is not required to use DTrace, and it seems that the gcc is broken. If can get a working gcc4.2 in the base system, you are ucky. Or, you can download a base system for the FreeBSD FTP site, and install it to a temp path, then copy the gcc binary to /usr/bin. > > Regards, > Nikolay > -----BEGIN PGP SIGNATURE----- > Version: GnuPG/MacGPG2 v2.0.17 (Darwin) > Comment: GPGTools - http://gpgtools.org > > iEYEARECAAYFAk2S4nMACgkQHNAJ/fLbfrmHJwCgmpMQVdv5DUuz+exWyTIsew0/ > 0EcAn0kMguIUwwczwDxKeayG9pEDRiBy > =K4KJ > -----END PGP SIGNATURE----- > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" > -- Zhihao Yuan The best way to predict the future is to invent it.
