Wild guess, you installed gmp and mpfr into a nonstandard location and didn't add the dir to LD_LIBRARY_PATH. > config.log really doesn't give any interesting details, so i hope you > can help me solve this problem.. On the contrary, it contains the exact details necessary to diagnose this problem, but most likely you're looking at the wrong config.log. There's one in each directory where configure is run, so if you're looking at the one in the toplevel that's not where the interesting parts are. Look at (and post the contents of) the one in the directory corresponding to "configure-stage1-target-libgcc". Brian
