cpp_dll export error

[helloworld1l]

hi.
cpp_dll now exports properly, but an error is reported when using it. I found that in the clipper.h file, the classes RectClip and RectClipLine have methods with the same name, and the VS compiler prompts that "rc" uses an undefined class "Clipper2Lib::RectClip::RectClip" in line 204, how to solve it?

Oops, yes, that's poor design and needs fixing.

Edit:

I found that in the clipper.h file, the classes RectClip and RectClipLine have methods with the same name

I'm presuming you mean that clipper.h has functions named using classnames (which is confusing).
Obviously classes with methods of the same name are constructors 😁.

No, the constructor of RectClip is in the file clipper.rectclip.h, the error here is about the unrecognized dll library export.

[AngusJohnson]

I'm hoping this is now fixed in the latest commit.
I've renamed all RectClip functions in clipper.h (and clipper.cs) to ExecuteRectClip.
And likewise in clipper.export.h, I've renamed these exported functions similarly.

Delphi is little behind. Stack overhead? Memory manager overhead?

Yes, it's slower. Sadly the relatively small Delphi user base means that Embacadero can't compete with the likes of Microsoft and the resources they can throw at their C++ compiler.
