Due to the server layout I can't install anywhere except in /opt. Apologies, the original gmp layout was a mistake, I can confirm that my gmp is in the following location: file /opt/gcc/usr/lib/libgmp.so /opt/gcc/usr/lib/libgmp.so: symbolic link to `libgmp.so.3.5.2' file /opt/gcc/usr/lib/libgmp.so.3.5.2 /opt/gcc/usr/lib/libgmp.so.3.5.2: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), not stripped My server is: uname -a Linux sn37v98 2.6.16.60-0.69.1-smp #1 SMP Fri Sep 17 17:07:54 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux With regards to the LD_LIBRARY_PATH, I’ve generally not liked its use. I know it will work when I set it with the location, but I would prefer to pass the details via the configure script. Is there a way to do, it given the –with-gmp doesn’t work for the second stage? 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" were done to aid in finding mpc etc, which are located in another location i.e.: /opt/gcc/lib and /opt/gcc/lib64 I’ll cut down the configure options to reflect some of your changes. Any help would be appreciated. Many thanks Dan
