Hello,

I need to use a C++ SDK to create a plugin an existing closed source c++ application and I would like to know if its possible to use D for that task.

Would is be possible to port the SDK header files and call the exposed functions inside the C++ program from a D dynamic library?

Is it possible at all?

Thank you very much!

Try looking at this:

Yes, but it depends on the complexity of the headers. C++ templates aren't supported for example. There have been recent improvements to C++ compatibility, including namespace support, methods etc. and work is ongoing to get even more working.

How large is the API? Sometimes the easiest approach is to create a simple extern "C" wrapper in C++ and then call that from D, as D has excellent C compatibility. See http://dlang.org/interfaceToC

Templates are supported, if they're already instantiated.

Sorry, yes, I should have clarified that.
