Joseph, Hi, sorry for the troubles! I am having difficulty seeing this fail on my system. I built gmp from upstream, installed it, and pointed to the install location with --with-gmp. Which stage does your build fail at? I am actually not totally sure how to respect the -with-gmp argument in libcc1. auto* tools are not my strongest skill. ;) I notice gcc/configure.ac I think just exports the variables to Makefile.in from the main configure script. That what we should do in this case? Cheers Phil
