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

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

[Yuan, Sai (NSN - CN/Cheng Du)]

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:

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!
Sai

It's complaining that you haven't installed a 32-bit cross assembler.
I guess that's right, is it?  You didn't build cross-binutils for i386?

Why are you doing such a strange thing?  gcc will already generate 32-bit
code with "gcc -m32".

Oh! I didn't install a 32-bit cross assembler. Where can i get this stuff?
I didn't use "-m32" because it also compile in Clearcase environment. It's not easy for me to add this flag.

Thanks very much
Sai

Please don't top-post.

It's all part of GNU Binutils.

You have got to be joking!  Are you telling me that Clearcase is so
unspeakably awful that you cannot control any compiler flags?

Are you telling me that you cannot use a shell script to exec gcc
with the -m32 flag?

Hi 

To my knowledge I do not think we can create a 32-bit gcc on a 64-bit OS. What I did was to compile and create a 64-bit gcc and then use -m32 flag to make it compile in 32-bit. Did this on RHEL5.1 and the gcc version is 4.1.2.

With Regards
