Unresolved external symbol ExecuteInternal - Am I not linking correctly?

[burhop]

I've been using Clipper2 as a DLL from C++ with no problems until I called this function and got an "Unresolved" error:

Clipper2Lib::Paths64 result = Clipper2Lib::Difference(top, bottom, Clipper2Lib::FillRule::EvenOdd);

My first guess is that I'm not including Clipper2_64.lib in my build. The other functions were working because they were inline functions in the headers. Difference eventually calls ExecuteInteral in a .cpp file so would need the library at link time.

However, I have Clipper2_64.lib as "Additional Dependencies" and I have its location in "Additional Library Dependences ( $(SolutionDir)..\Clipper2\DLL\CPP_DLL\x64\$(Configuration) Where SolutionDir is my project. The Lib is in the directory and the path resolves to that location for both debug and release.

I'm 50% sure I've got some error keeping me from pulling the .lib file. But since I noticed the DLL export functionality is relatively new, I thought I'd check here should anyone else have an idea or recommendation?

Thanks (Clipper2 newbie)

So I just pulled the Cpp files local which is maybe the right way to do this.

Thanks for the feedback.
This sounds like an error in the DLL which I'll investigate (sometime soonish - eg this coming week 😉.

No hurry. Clipper is not big enough to make pulling the source locally a problem.

OK, I've finally gotten around to looking at this.
The reason your call to Difference is producing errors is because that function isn't exported.
In its place, you can call the BooleanOp64 function (passing ClipType::Difference as the first parameter).
Currently there's no HTML documentation on Clipper.Header and I hope to remedy that soon.
