hello. i have been able to create .lib files and .dll files that use just the core c++ language, and reference them fine. as soon as i bring darkgdk into the mix, it all falls apart. here are the methods i have tried to make this work:

1: create a basic darkgdk game using a wizard, then change the output type to .lib/.dll, as well as the various other settings
problem: the including file has no problems, the library files cannot seem to find any darkgdk functions
2: create a .lib using the many tutorials on the internet, then change the ignored libraries to that of a darkgdk file.
problems: very low level libraries become unresolved, no combination of ignored libraries fixes the problem.
3: create an empty project, add a .h and .cpp, then copy all properties from a working darkgdk file (sans output type).
problems: the main darkgdk function needs to be defined, an as this is not an application, defining it would override any definition in the including code.

what do i do? i have completely run out of ideas!

What errors are you getting?
Do you get errors when building or when trying to include the lib?

i do beleive i made it quite clear, but ill put them again"

1st method: unresolved symbol "any dark gdk function here" referenced in "my function here" (x100)
2nd method: "some library" conflicts with "other library", upon ignoring one: unresolved symbol "some function name i cannot make out" referenced in "my function"
3rd method: unresolved symbol "DarkGDK()" referenced in _WinMain@16

First off, you can't make a DLL that uses the GDK. It will *not* work! This is because the global objects of the GDK itself will be contained within the EXE file *and* the DLL file that you are trying to create.

Second, when creating a .LIB file, you can't use any of the debug runtimes (just like in a GDK program) you have to use the /MT compiler setting and not the /MTD.

In short, when creating a .LIB file, you have to use the same compiler settings as GDK programs if you plan on using it with the GDK itself.

I hope this helps,

ok solved that problem, but now i have _invoke_watson multiply defined, and ignoring the either and both libraries that conflict result in 20 or more instances of undefined symbols

Copy the linker and runtime library settings directly from a working DarkGDK program to the .lib project.
