A METHOD OF CREATING SOFTWARE THAT IS PORTABLE ACROSS DIFFERENT OPERATING SYSTEMS

摘要

The invention provides a technique for producing software that is `portable', i.e. is compatible with two or more different operating systems. First and second software applications are generated from source code written for a first OS; both software applications can however run on a second OS when each referencing interface libraries that (a) mimic the APIs for the first OS and (b) also interface to APIs that are native to the second OS. The applications are each tightly integrated with different instances of interface libraries that are not shared between the first and second applications.
