But the best way i have found is by not building gcc within it source directory. So do somthing like: $ mkdir gcc-build $ cd gcc-build $ ../gcc/configure --enable-languages=c,c++ --prefix=... --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib --with-mpfr-include=/usr/local/include --with-mpfr-lib=/usr/local/lib --with-ppl-include=..... Would be a way i do it on my laptop where i have local installed versions of the different depandancies. But i think using the --with-ppl=/usr/local would work you just point it to the directory were the respected lib and include folders are i think. Hope this helps! --Phil
