Thank you for reply! Following I will explain the problem in more detail. I compiled GMP, MPFR, MPC in each own directory and installed them all in /lab/home/zuoqi/gcc32/gcc-gnu-ccs . The configuration is as following: #!/bin/sh cd /lab/home/zuoqi/gcc32/build-gmp-gnu-ccs rm -rf * ../gmp-5.0.1/configure --prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-ld ABI=32 make -j 64 make check make install cd /lab/home/zuoqi/gcc32/build-mpfr-gnu-ccs rm -rf * ../mpfr-3.0.0/configure --prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-ld --with-gmp=/lab/home/zuoqi/gcc32/gcc-gnu-ccs ABI=32 make -j 64 make check make install cd /lab/home/zuoqi/gcc32/build-mpc-gnu-ccs rm -rf * ../mpc-0.9/configure --prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-ld --with-gmp=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-mpfr=/lab/home/zuoqi/gcc32/g cc-gnu-ccs ABI=32 make -j 64 make check make install echo lib DONE! Then I compiled GCC4.6.0 in its building directory, as following #!/bin/sh LD_LIBRARY_PATH=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib export LD_LIBRARY_PATH cd /lab/home/zuoqi/gcc32/build-gcc-gnu-ccs rm -rf * ../gcc-4.6.0/configure ABI=32 --prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-as --with-as=/usr/local/bin/as --with-gnu-ld --with-ld=/usr/local/bin/ld - -enable-languages=c,c++,java --with-gmp-include=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/include --with-gmp-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib --with-mpfr-inc lude=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/include --with-mpfr-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib --with-mpc-include=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/incl ude --with-mpc-lib=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib --without-ppl --without-cloog --enable-plugin --enable-lto make -j 64 make check make install echo gcc DONE! Without the LD_LIBRARY_PATH setting, I can't manage to compile. Without ABI=32, GMP, MPFR, MPC will generate 64-bit libraries. When building GCC4.6.0, there will be 32/64 problems. To check my GCC, I tried as you suggested using "-v" Before I set LD_LIBRARY_PATH, GCC4.6.0 can't find mpc. -bash-3.00$ /lab/home/zuoqi/gcc32/gcc-gnu-ccs/bin/g++ hello.cpp ld.so.1: cc1plus: fatal: libmpc.so.2: open failed: No such file or directory g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate.
