We can not possibly support all of the effectively infinite numbers of knobs and switch you can set in the build process. If you want to veer far outside the lines of well documented routes, it's up to you to find and fix problems. > > First off I assume that since you posted to freebsd-current@ that you > > are running the latest head. > > Yes: > > On Wed, Jun 05, 2013 at 08:53:14PM +0200, d...@gmx.com wrote: > >> Installed system revision: 251046. > >> Checked out source tree revision: 251352. > > > Setting CC, CPP, and CXX except in the environment isn't supported and > > can't work for cross build cases.

If you XCC, XCPP, and XCXX you may not need CC, CPP, and CXX at all, though your environment is weird enough I won't assert that. > > I see that WITHOUT_KERBEROS is not set here. Was it ever?

I've not experienced the kerberos failures so I'm not sure if this is one or not. I suspect there is another error further up in your output, but it's hard to say. If this is a parallel build there have been reports of kerberos build failures with high levels of parallelism. It may be that something you've disabled results in the presumed makefile bug being easier to trigger. > >> When building the system that is currently installed, the following > >> "compiler" was used: > >> ======= /path/to/clang begins ======= > >> #!/bin/sh > >> /path/to/real/clang "$@" || /path/to/real/clang > >> --sysroot=/usr/obj/usr/src/tmp "$@" > >> ======= /path/to/clang ends ======= > > > > This has got to corrupt your build.
