Abstract: A method and apparatus, for providing seamless porting of source code originally written in Visual C++ for use under the Microsoft Windows operating system (WOS) environment, to computers operating under other Operating Systems such as the UNIX operating system (UOS), for the purpose of compilation and execution therein, comprising at least one computer using WOS and one computer using another OS, e.g. UOS, linked such that when a compilation of a C++ source code is initiated on the computer using the WOS, it is intercepted, and transferred to the computer using the UOS, for continuation of the compilation process. The source code is compiled for execution on the computer using the UOS, resulting in a UOS object code.
