How to run 64 bit apps on 32 bit os

I am using 32 bit openSUSE OS, and I am using a cross compiler to build 64 bit application( it does not support building 3开发者_JAVA百科2 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.

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

Short answer: No, there is no way.

Longer answer: If you have a 64-bit CPU it may be possible to run a 64-bit virtual machine, even though your host OS is 32-bit. I'm not 100% sure about that, though, you'd have to try it.
