How to build 32bit binary on 64bit Linux

Hi, I want to build 32bit binary on 64bit Linux computer.

I downloaded of_v0.9.8_linux_release which is for 32bit computers.

But if I do the following in terminal

cd OF/scripts/linux
./compileOF.sh

Then it prints the following error message

makefileCommon/config.shared.mk:217: *** This package doesn't support your platform, probably you downloaded the wrong package?.  Stop.
there has been a problem compiling Debug OF library
please report this problem in the forums

Can anyone please teach me how to do this?
Thanks in advance!
