C++ pragmas

C++ pragmas

[max1]

Hi,

Reading GNAT Reference manual about pragma CPP_Constructor I found:

"Pragma `CPP_Constructor' is intended primarily for automatic
generation using an automatic binding generator *tool*."

Where is such tool? Is it free available?
What other Ada compiler supports C++ interfacing?

Is there proposition for C++ interfacing in next Ada standard?

Thank you

Maxim Reznik

You can already interface to C++ without using the GNAT-specific pragmas.

I don't know of such a tool off the shelf.

However, one could build such a tool with the DMS Software Reengineering
Toolkit.
(See http://www.semanticdesigns.com/Products/DMS/DMSToolkit.html).
It is as to parse/process both Ada and C++, and could be configured
to parse Ada, extract Ada function/package signatures, and generate
the corresponding C++ interfaces, or vice versa.

This isn't a weekend project, but if you had a lot of interfaces,
it would be a definite long term gain.

YMMV.
