--- Comment #1 from Mikael Pettersson <mikpelinux at gmail dot com> --- > ld.so.1: cc1: fatal: libmpc.so.3: open failed: No such file or directory > xgcc: internal compiler error: Killed (program cc1) You need to 1. Tell the dynamic linker where to find the gmp etc shared libraries, or 2. Build gmp etc as non-shared libraries, or 3. Install the gmp etc shared libraries in a standard location. Not a gcc bug.
