Any suggestions why the failed program confdefs.h isn't working? As the installation instruction say, we recommend against running ./configure. Run configure in an empty directory instead. I recommend unpacking the sources from scratch to avoid confusion left behind by ./configure. However, your specific problem is this: > configure:2156: gcc conftest.c >&5 > gcc: error trying to exec 'as': execvp: No such file or directory You don't have an assembler on your path. Your compiler--the one you are going to use to build gcc--doesn't work. Ian
