--- Comment #150 from Iain Sandoe <iains at gcc dot gnu.org> --- > ./configure --prefix=/opt/local --build=powerpc-apple-darwin9 Hopefully, you are NOT configuring in the source directory? Surely macports does not do that .. it is not supported. https://gcc.gnu.org/install/configure.html "First, we highly recommend that GCC be built into a separate directory from the sources which does not reside within the source tree. This is how we generally build GCC; building where objdir is a subdirectory of srcdir should work as well; building where objdir == srcdir is unsupported."
