In order to build a GCC that can build 64-bit binaries, you need to have a 64-bit C library and 64-bit binutils installed. Do you? There is a shell script config.guess in the top level GCC directory. When you run it, does it print x86_64-unknown-linux-gnu or i686-unknown-linux-gnu? If it prints i686, that suggests that uname -m on your system prints i686, and that suggests that your kernel is not running in 64-bit mode. Ian
