Would there be any *sense* in that, though? :) The only reason -DNOCLEAN speeds up things is that it only rebuilds files that depend on files that have actually changed. In that case, I don't see how ccache could help - if a header file has changed, the C preprocessor output will definitely not be the same, and ccache will certainly rebuild the file. The only case in which -DNOCLEAN rebuilds something and ccache finds that it is just the same in the old version is when a change is committed and then *immediately* backed out, so that the only difference between the old and new files is in their $FreeBSD$ tag. This doesn't happen all that often, though :) G'luck, Peter --=20 Peter Pentchev roam@ringlet.net roam@cnsys.bg roam@FreeBSD.org PGP key: http://people.FreeBSD.org/~roam/roam.key.asc Key fingerprint FDBA FD79 C26F 3C51 C95E DF9E ED18 B68D 1619 4553 This sentence would be seven words long if it were six words shorter. --VbfcI4OLZ4XW0yH2 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFCE1sA7Ri2jRYZRVMRAvWZAKCBKagpyVGac+lkmcYQecy4WdM64QCfTyde vsY4YG0Lp2UK5Ijr3vJSoDk= =J10y -----END PGP SIGNATURE----- --VbfcI4OLZ4XW0yH2--
