Yes. I do this all the time. I never build in /usr/src or /usr/obj :-). One has to make sure that one has the right config to generate the compile tree with. I believe that the compilers are still compatable enough to allow this to happen. Building world can be done, but may require some hand steps. It has been a while since I've done this. > Also, can I build kernels for different architectures on a normal i386 box? Yes. See the recent cross compilation thread in freebsd-arch for details.
