I am not an expert in handling linux distribution and install directories :( > Hey You may want to simply move the latest source version and install libmpc (http://www.multiprecision.org/index.php?prog=mpc) aswell since the interfaces changed alot since then i based my old front-end code on a gcc 4.0 and i just ended up starting from scratch when working with trunk. But if you want to keep working with that version you can try: configure --enable-languages=c,c++,.... --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib ... do the same with --with-mpfr-{include,lib} if you have problems. When you manually make install by default things generally go to /usr/local/include for the headers then lib for the actual library you link against unless you specify a prefix. If you want some reference on front-end code you can look a little at mine though mine focuses on working with trunk http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/python?h=python Where pyspec.c is the compiler driver, then py-lang.c is the compiler proper then other files go along with it. Hope this helps in at least some way :) Its confusing but were working to make it simpler! Gcc rocks ;) --Phil /* Sorry forgot to cc the list :) */
