Multi-language compilation
View Patent ↗A system and method for multi-language compilation is provided. The system and method provide a mechanism for two or more separately written compiler components to co-operate in the compilation of mixed language compilation units. The system mitigates problems associated with conventional approaches to dealing with embedded code blocks. Extensibility is facilitated through the use of a common compiler infrastructure (CCI) in the form of a base class library. Compilers for specific languages are written as extensions of these classes. Common conventions and a flexible extensibility mechanism facilitate cooperation amongst the compilers.
