C++ Question Unresolved External Symbol problem

[DesideriusPapp]

Hi all!

This is my first post after my 'Hello' one in Announcements, so let me greet you all.

I've started making my first dll and I'm stuck - I believe I've thoroughly searched this forum and other sources for a solution but I don't seem to be able to solve this on my own.

I'm using VC++ 2008 Express.

I've setup the compiler according to the Wiki, successfully compiled ShuttlePB and then made some changes and again successfully compiled. Then I went for an animation.

From my understanding (I'm no programmer nor have previous experiences with C++), for animations I had to make an header file to define my class, so that I can make a constructor in the main .cpp file. So I think I did.

In the header file I included orbitersdk.h and put the following:

class Strelka: public VESSEL2 {
public:
Strelka (OBJHANDLE hVessel, int fmodel);
~Strelka ();
void clbkSetClassCaps (FILEHANDLE cfg);
private:
void DefineAnimations();
UINT BayAnimation;
};

then in the main .cpp I included the header file and put:

Strelka::Strelka(OBJHANDLE hVessel, int fmodel)
: VESSEL2 (hVessel, fmodel) {}

I'm reasonably sure the problem lies here because it's the only change to the previously working version of the code.

Anyway, the error is:

1>------ Build started: Project: Strelka, Configuration: Release Win32 ------
1>Compiling...
1>Strelka.cpp
1>Linking...
1> Creating library ..\..\..\Orbiter\Modules\Strelka.lib and object ..\..\..\Orbiter\Modules\Strelka.exp

1>Strelka - 2 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

can anyone help me out or put me on the right track?

Thank you in advance!

Either add realization for destructor (~Strelka()) in the .cpp or remove it from the .h file.

Oh my. Didn't think it was THAT simple :embarrassed:

Thank you!
