Travis Cobbs Wrote:64-bit Linux has always been able to run 32-bit executables, as far as I know. However, if you don't have a fully statically linked executable (and presumably you don't), then 32-bit versions of all of the shared libraries that you use must be installed, and this is often difficult.
I do link statically to all the 3rd party stuff I use (wxWidgets, pnglib, GLEW, boost) but as far I know that still leaves plenty of 32 bit dependencies. I always though you had to fool around with chroot to get it working on a 'out of the box' 64 bit setup.
