Read the "Installing GCC: Configuration" again. OK - I give up on this case as well :{ Me Myself etc., we've tried to help, but you keep ignoring the advice we're giving you. It explicitly says in the installation guide "do not run ./configure, this is not supported..." and links to the following FAQ - http://gcc.gnu.org/wiki/FAQ#configure You need to start from a clean, empty, NOTHING IN IT, directory. Unzip, untar or whatever the GCC sources, then create a NEW build directory NEXT TO GCC :- anemptydirectory | | > gcc-4.6.3 | | > mybuilddirectory Then :- cd mybuilddirectory ../gcc-4.6.3/configure make Other people have no problem with this, and I use it all the time to build cross compilers for the project I'm working on. I can't understand why you have such a resistance to doing it as recommended by the GCC build instructions - they are there for a reason and ignoring them will likely lead to a build failure, as you've already discovered.
