How to run 64 bit apps on 32 bit os

Question

I am using 32 bit openSUSE OS, and I am using a cross compiler to build 64 bit application( it does not support building 32 apps) as our software will be deployed on a machine which is 64 bit OS. As testing on target is not always possible, is there anyway to run this applications on my 32 bit OS.

Answer 1

Use something like QEMU that can emulate a 64-bit processor.
