Hello! I've been trying to build gcc-4.4.2 on Tru64 UNIX. With some minor glitches I've compiled and installed both GMP 4.3.1 and MPFR 2.4.2 with --prefix=/opt/gcc Then I've tried to compile gcc itself: # cd obj # ../src/configure --prefix=/opt/gcc --with-gmp=/opt/gcc --with-mpfr=/opt/gcc # gmake -j6 bootstrap [...] gmake[3]: Leaving directory `/usr/src/gcc/obj/gcc' mkdir alphaev56-dec-osf5.1b/libgcc Checking multilib configuration for libgcc...
