I have been wrestling with building gcc-4.5.1 on an old Linux i686 machine running SuSE 10 with gcc-4.0.3. I have updated libtools and m4. I have successfully built gmp, mpfr, and mpc. I have passed to configure the '--with-X=Y' options to where gmp, mpfr, and mpc are installed. I have defined LDFLAGS with the location of their libraries. I have passed the '--with-stage1-ldflags=X' option with the same information. All this, yet I still get a build failure with these messages in the "gcc_build/i686-pc-linux-gnu/libgcc/config.log" (note the build directory is outside the gcc source tree): gcc version 4.5.1 (GCC) configure:3004: $? = 0 configure:2993: /home/tmb/src/gcc_build/./gcc/xgcc -B/home/tmb/src/gcc_build/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -V >&5 xgcc: '-V' must come at the start of the command line configure:3004: $? = 1 configure:2993: /home/tmb/src/gcc_build/./gcc/xgcc -B/home/tmb/src/gcc_build/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -qversion >&5 xgcc: unrecognized option '-qversion' xgcc: no input files configure:3004: $? = 1 configure:3020: /home/tmb/src/gcc_build/./gcc/xgcc -B/home/tmb/src/gcc_build/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -o conftest -g -O2 conftest.c >&5 /home/tmb/src/gcc_build/./gcc/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory configure:3023: $? = 1 configure:3211: checking for suffix of object files configure:3233: /home/tmb/src/gcc_build/./gcc/xgcc -B/home/tmb/src/gcc_build/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -c -g -O2 conftest.c >&5 /home/tmb/src/gcc_build/./gcc/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory Note that the fatal error is that libmpc.so.2 cannot be found yet I can see it in the place I told configure to look. Am I missing some configuration option? Any other ideas? Note: I have built gcc-4.5.1 successfully on two other, more modern systems (but with test results that may be questionable--reported to this list). Thanks. -Tom Thomas M.
