--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Are you building in the source tree? > ./configure This makes it look like you are. from 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.
