--- Comment #5 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Francois-Xavier Coudert from comment #4) > INVALID, then. I need a better way to create this cross-compiler. The way to build cross compilers for GCC is: 1. build a native compiler for source 2. build a cross compiler from the same sources using (1). Trying to use clang as a cross-bootstrap for GCC is going to be (very) unreliable at best and most likely will fail (I quite regularly get non-bugs reported from attempts to do this). I regularly build crosses and native crosses and (apart from one small amount of magic needed to get the linker version passed to a native cross) it works reliably (including Ada).
