How to install 32 bit gcc on 64 bit RHEL5.1

["Yuan, Sai (NSN - CN/Cheng Du)" <sai.yuan@nsn.com>]

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

...

[root@aries gcc-4.1.2]# make

It caused me to doubt whether it can install 32 bit gcc on 64 bit Linux. Btw, the version i want to install is 32bit gcc 4.1.2.
Could you please help me?

Thanks in advance!
