Hello! I am suffering from this issue for a long time. Could you please give me any good idea? When I tried to install a 32bit gcc on 64 bit Linux, I got this error: [root@aries gcc-4.1.2]#./configure --prefix=/opt/gcc/linux/gcc-4.1.2 --host=x86_64-redhat-linux --cache-file=/dev/null --target=i386-redhat-linux ...

Btw, the version i want to install is 32bit gcc 4.1.2. Could you please help me? Thanks in advance! Sai
