Many times in the past, I have read on various project forums that people with 64 bit linux *also* has to install the 32 bit stuff in order to get some projects to run successfully. I just installed 64 bit opsnsuse on several VMs, and I want to make sure I don't run into that problem.

Can someone please tell me what those 32 bit file are, that I need to install? Also, I think I remember someone saying that some linux distros include the 32 bit files in the default 64 bit installation. Does anyone know if that is true for opensuse?
