Thanks Paolo, Here's what I have so far. ../gcc/configure CFLAGS="-g" --enable-languages=c,c++ --enable-checking --disable-bootstrap --prefix=$PWD/../prefixdir Hopefully I'll be able to debug gcc nicely after this is built. Two more questions that could save me a lot of time. Do you know where the abstract syntax tree is stored in GCC after a file is parsed? Does GCC still create an AST for C/C++, or does it go directly to GIMPLE? Thanks for the help, Bob Rossi
