The huge market of smartphones demands a vast number of applications with varying capabilities. For this, it is desirable that capabilities of two or more pieces of executables will be delivered together. However, several operation systems, such as Apple iOS, do not allow downloading an application with more than one binary executable file. The purpose of this invention is to allow merging of several, two or more, pieces of binary executables, without an access to any of which source code. The merging process will handle the addressing environment required for correct code operation—creating a single virtual memory space and adapting the binding addresses, offset addresses and base addresses. This will enable executing all desired functionality from a single piece of a binary executable which can be downloaded as a single application from the app store. Problems of existing mobile OSes for application downloading will be resolved.
