For what it is worth, I really and truly believe this problem is solvable, along with the problem of cross-compiling, if only folks want to spend the time to make it work. Certainly NetBSD is a good example of a full OS that cross-builds even from non-native OS'. I've made this work well with some kernel bits from Solaris, but never with an actual Solaris tree. The Makefiles have all kinds of 'orrible assumptions in them about their build environment. I'd be willing to contribute some time assisting in an effort to address this (especially the kernel bits), but the job is too big for a single person, I think, and it would have to have the blessing of the Sun folks, because, quite honestly, a lot of churn in Makefiles and packaging and such would have to happen. I dearly wish I could cross compile SPARC from my amd64 machine. -- Garrett D'Amore, Principal Software Engineer Tadpole Computer / Computing Technologies Division, General Dynamics C4 Systems http://www.tadpolecomputer.com/ Phone: 951 325-2134 Fax: 951 325-2191 _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
