Using C++ libraries with Adept

[ghost]

I think I will need to create C wrapper first before I could use it with Adept? This is the normal procedure that is also true with other languages I have used. But recently, FreeBASIC introduced the feature to work with C++ libraries directly. Please have a look at this project to see how they are using it:

This changed my mind and now I think it's possible to use C++ libraries directly without C wrappers. Since I'm new to Adept and I don't know how Adept handles it so instead of just following the normal procedure I already know, I think I should ask you directly.

Yes only C symbols can be used from Adept. In order to allow C++ symbols without using a C wrapper, Adept would have to replicate the same behavior that C++ uses for classes, including things like copy constructors, move constructors, destructors, overloaded operators, etc. all in the same way that C++ does it.

Correct me if I'm wrong, but it looks like FreeBasic compiles to C/C++, which is why it's able to do that so easily. Adept compiles to machine code, so can't just emit C++ classes like that (it would have to handle a lot of the C++ behavior itself).

This might be something to look into more in the future, but it seems difficult to implement correctly

FreeBASIC compiles to plain C like Adept, not C++. It also has a GNU Assembler backend that compiles to assembly instead of C.

Interesting, I couldn't find the details of how their classes are implemented, so would love to see what they do

I hope you could learn something cool from the way FreeBASIC is implementing it. But please note that I don't ask you to do the same as FreeBASIC. I'm not asking for this feature. This is a question and you already gave me the answer that C wrapper is needed. As far as I know, FreeBASIC's hack has it own limitations. I think I would better go with C wrapper.
