It's certainly okay to use it if you started a clean build, it failed for some reason, you corrected a cause, and want to resume. If may also work if you've updated the sources, but no guarantees -- often it has been shown that "make clean" is necessary to remove some old cruft that now conflicts with the new sources. For example, if compiler sources have been updated, it can generate different code, but foo.o will only depend on foo.c, and will not be rebuilt if you use -DNOCLEAN. In short, don't use it if you don't fully understand all the consequences. ;) Cheers, --=20 Ruslan Ermilov ru@FreeBSD.org FreeBSD committer --8X7/QrJGcKSMr1RN Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFBH8L1qRfpzJluFF4RApYhAJ4tEPwJBBKjnQBnrJ7n/uLZnqjBGQCfTe// pETYjd8Q5ciAr7AvxECx8Tg= =EMle -----END PGP SIGNATURE----- --8X7/QrJGcKSMr1RN--
