2.11 Building Mixed Ada and C++ Programs

A programmer inexperienced with mixed-language development may find that building an application containing both Ada and C++ code can be a challenge. As a matter of fact, interfacing with C++ has not been standardized in the Ada 95 Reference Manual due to the immaturity of – and lack of standards for – C++ at the time. This section gives a few hints that should make this task easier. The first section addresses the differences regarding interfacing with C. The second section looks into the delicate problem of linking the complete application from its Ada and C++ parts. The last section gives some hints on how the GNAT run time can be adapted in order to allow inter-language dispatching with a new C++ compiler.
