Dear All: I am trying to compile gcc 4.2.4 on a CentOS 5.3 [misha@mackey ~]$ cat /etc/redhat-release CentOS release 5.3 (Final) [misha@mackey gcc-4.2.4]$ uname -a Linux mackey.cluster 2.6.18-128.7.1.el5 #1 SMP Mon Aug 24 08:21:56 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux system so I can use the ATLAS program http://math-atlas.sourceforge.net/atlas_install/ I am getting a rather strange error after doing ./configure --prefix=/home/misha/gcc and make Making all in src make[4]: Entering directory `/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src' /bin/sh ../libtool --tag CXX --mode=compile /home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc/xgcc -shared-libgcc -B/home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc -nostdinc++ -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -B/home/misha/gcc/x86_64-unknown-linux-gnu/bin/ -B/home/misha/gcc/x86_64-unknown-linux-gnu/lib/ -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/include -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/sys-include -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include -I/home/misha/gcc/gcc-4.2.4/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -g -O2 -D_GNU_SOURCE -c -o codecvt.lo ../../.././libstdc++-v3/src/codecvt.cc /home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc/xgcc -shared-libgcc -B/home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc -nostdinc++ -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -B/home/misha/gcc/x86_64-unknown-linux-gnu/bin/ -B/home/misha/gcc/x86_64-unknown-linux-gnu/lib/ -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/include -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/sys-include -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include -I/home/misha/gcc/gcc-4.2.4/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -g -O2 -D_GNU_SOURCE -c ../../.././libstdc++-v3/src/codecvt.cc -fPIC -DPIC -o .libs/codecvt.o /home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc/xgcc -shared-libgcc -B/home/misha/gcc/gcc-4.2.4/host-x86_64-unknown-linux-gnu/gcc -nostdinc++ -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src -L/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -B/home/misha/gcc/x86_64-unknown-linux-gnu/bin/ -B/home/misha/gcc/x86_64-unknown-linux-gnu/lib/ -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/include -isystem /home/misha/gcc/x86_64-unknown-linux-gnu/sys-include -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/include -I/home/misha/gcc/gcc-4.2.4/libstdc++-v3/libsupc++ -fno-implicit-templates -Wall -Wextra -Wwrite-strings -Wcast-qual -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -g -O2 -D_GNU_SOURCE -c ../../.././libstdc++-v3/src/codecvt.cc -o codecvt.o >/dev/null 2>&1 make[4]: *** [codecvt.lo] Error 1 make[4]: Leaving directory `/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3/src' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/misha/gcc/gcc-4.2.4/x86_64-unknown-linux-gnu/libstdc++-v3' make[1]: *** [all-target-libstdc++-v3] Error 2 make[1]: Leaving directory `/home/misha/gcc/gcc-4.2.4' make: *** [all] Error 2 [misha@mackey gcc-4.2.4]$ I don't actually see any error which is why I can't seem to figure this out further.
