I recently had to build a -current kernel on -stable too, and ended up with this in the config file: makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols # kernel cross-build... makeoptions CC=gcc295 options __FreeBSD__=4 # needed? options unix options __FreeBSD_cc_version=400003 I don't know if the last two are really needed and the DEBUG of course is optional too, but without the others my kernel wouldn't even build. (I forgot what exactly failed with the old cc, but the __FreeBSD__=4 is necessary for parts that use #ifdefs to decide things like which version of a kernel interface to use, the case of this i saw was in the isdn stuff. Of course this produces redifinition warnings so probably should be done some other way but at least it works... :) Regards, -- Juergen Lock <nox.foo@jelal.kn-bremen.de> (remove dot foo from address to reply) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
