The SDK used for cross-compilation of the executables should handle issues such as library versions (and of course, CPU architecture and endian-ness). I've never done cross-compilation for the same architecture, so I don't know how that would work, but I presume there is some way to compile code for another system with the same architecture but different libraries. -- Tim
