GNAT supports interfacing with the G++ compiler (or any C++ compiler generating code that is compatible with the G++ Application Binary Interface —see http://www.codesourcery.com/archives/cxx-abi).
Interfacing can be done at 3 levels: simple data, subprograms, and
classes. In the first two cases, GNAT offers a specific
CPP) that behaves exactly like
Usually, C++ mangles the names of subprograms. To generate proper mangled
names automatically, see Generating Ada Bindings for C and C++ headers).
This problem can also be addressed manually in two ways:
Interfacing at the class level can be achieved by using the GNAT specific
pragmas such as
CPP_Constructor. See Interfacing to C++, for additional information.
