Hi Vijay, Make sure you've done this (presuming GCC has been untarred to /home/vsheshan/gcc-3.3.1): cd /home/vshan mkdir mygcc cd mygcc /home/vseshan/gcc-3.3.1/configure --prefix=/home/vseshan/local/gcc-3.3.1 --with-local-prefix=/home/vseshan/local/gcc-3.3.1 As I understand it, you cannot create GCC from within the source directory of GCC.
