Is there a way to > do, it given the –with-gmp doesn’t work for the second stage? --with-gmp would work if you said --with-gmp=/opt/gcc/usr instead of /opt/gcc But it would still need to find the shared libs at runtime, which is why I suggest the use of LD_LIBRARY_PATH. The other options are to link statically to gmp (the easiest option IMHO) which is what my config-gcc.mk makefile configures, by putting the GMP, MPFR and MPC sources in the GCC source tree. If you want to hardcode the library locations into the gcc executables you can try using the -R or -rpath linker options, but the -L options you're passing to configure will not help. > Also I’ve compiled the same gcc with just a prefix location and > nothing else in the configure argument except the environment > variables but it still didn’t build, I had to set LD_LIBRARY_PATH to > make it find mpr, gmp etc... > > The various environment variables set: > >>> CC=/opt/utils/usr/bin/gcc CXX=/opt/utils/usr/bin/g++ CFLAGS="-g3 -O0 >>> -I/opt/utils/usr/include" BOOT_LDFLAGS="-L/opt/gcc/lib >>> -L/opt/gcc/usr/lib -L/opt/utils/lib -L/opt/utils/usr/lib" Just use --with-gmp and --with-mpfr and --with-mpc instead. They set the include dirs and lib dirs correctly (assuming you give the right path, which seems to be /opt/gcc/usr not /opt/gcc as you have been using) But, as I said above, that won't remove the need for finding the shared libs at runtime. > were done to aid in finding mpc etc, which are located in another location i.e.: > /opt/gcc/lib and > /opt/gcc/lib64 If you'd put gmp in there too it would've made things a bit simpler :-)
