Hi Alexander, Did you follow these instructions... http://gcc.gnu.org/install/configure.html ...? In particular, the part that states... - - - - - - - - - - - - - - - - - - - - - - - - - - - - - First, we highly recommend that GCC be built into a separate directory than the sources which does not reside within the source tree. This is how we generally build GCC; building where srcdir == objdir should still work, but doesn't get extensive testing; building where objdir is a subdirectory of srcdir is unsupported. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - In my experience, when srcdir is the same as objdir, I have never successfully been able to build GCC.
