Hi,

This morning, I saw on fpc-devel a message titled `CPPClass`, which made me wonder if this keyword means what its name implies. Sadly though, there is not much documentation on this subject (read: none I could find other than some messages in the mailing list archive).

Is there anyone who could shed some light on this? (Links to documentation I missed will do :-) )

CPPClass - to the best of my knowledge - does not work. An attempt to implement it was made once, but never was finished.

That's why you don't find any documentation on it.

Yeah, that explains it indeed. Thanks for the pointer!

It's a experimental feature in its infancy. Some years old already and a few years ago "a bit" improved by me. So currently you can import C++ classes (generated by GCC or CLang!) that either have static methods or non virtual ones and call them. What currently does not work is instantiation and destruction of such classes, using virtual methods, operator overloads and C++ exceptions. I still plan to improve this feature further, but with all one needs to find time...

For its usage you can take a look at $fpc/tests/test/cg/tcppcl{1,2}.pas with the corresponding C++ files residing inside the obj/ subdirectory of cg/.

I really hate to lengthen other people's todo lists, but don't forget namespaces ;-) Anyway, good luck the implementation of these cool features!

That helps, thanks!
