I have a set of the required libraries built and installed into separate directories, so when gcc is configured with:
../configure --prefix=/opt/tools/gcc-4.8.1 --with-gmp=/opt/tools/gmp-5.1.2 --with-mpfr=/opt/tools/mpfr-3.2.1 --with-mpc=/opt/tools/mfr=/opt/tools/mpfr-3.2.1 --with-mpc=/opt/tools/mpc-1.0.1 --with-ppl=/opt/tools/ppl-1.1 --with-cloog=/opt/tools/cloog-0.18.0 --enable-languages=c,c++ --disable-multilib during configure-stage1-target-libgcc: configure: error: cannot compute suffix of object files: cannot compile and config.log contains: configure:3565: checking for suffix of object files configure:3587: /mnt/local/piotrw/build/gcc-4.8.1/objdir/./gcc/xgcc -B/mnt/local/piotrw/build/gcc-4.8.1/objdir/./gcc/ -B/opt/tools/gcc-4.8.1/x86_64-unknown-linux-gnu/bin/ -B/opt/tools/gcc-4.8.1/x86_64-unknown-linux-gnu/lib/ -isystem /opt/tools/gcc-4.8.1/x86_64-unknown-linux-gnu/include -isystem /opt/tools/gcc-4.8.1/x86_64-unknown-linux-gnu/sys-include -c -g -O2 conftest.c >&5 /mnt/local/piotrw/build/gcc-4.8.1/objdir/./gcc/cc1: error while loading shared libraries: libmpc.so.3: cannot open shared object file: No such file or directory configure:3591: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "GNU C Runtime Library" | #define PACKAGE_TARNAME "libgcc" | #define PACKAGE_VERSION "1.0" | #define PACKAGE_STRING "GNU C Runtime Library 1.0" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "http://www.gnu.org/software/libgcc/"; | /* end confdefs.h. */ | | int | main () | { | | ; | return 0; | } configure:3605: error: in `/mnt/local/piotrw/build/gcc-4.8.1/objdir/x86_64-unknown-linux-gnu/libgcc': configure:3608: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. which indicates that the configure scripts somehow failed to add the mpc libpath to the command line.
