Hi,
I first made the gdkengine.dll file with my plugins from the dark studio bonanza except darkphysic, i used darkdynamics instead.
so i proceeded to follow all the creating a project steps for vs2010.
i did it all by the letter, however i get these errors when compiled.

This may help.

The methods listed in that error are all in 'simpleWindow.h' and 'simpleWindow.cpp' included with Dark GDK 2.0. Are these definitely in your project and 'simpleWindow.h' included in the file where you are calling those methods? If they are, is 'Windows.h' being found correctly (C++ set up to include the right include and lib directories)? I'm pretty new to C++ so sorry if this doesn't help.

The link Hawkblood is to one of my threads. DarkDynamix is not currently supported so I have made a work around. However, this is not the cause of the errors you're getting.

[Edit] Ignore my first paragraph. I've tried altering my project to match and didn't manage to reproduce the same errors you got. Sorry! I'll keep thinking and let you know if I work it out.

[/Edit]

[Edit 2] Having looked again, I think it may be a C++ directory linking issue. Did you follow the step regarding adding the project's own directory to the list of dependencies? If not then maybe read that section and follow the steps and see if it helps. [/Edit 2]

"unresolved external symblol" errors means there is a call to a prototype without having a corresponding function. I may be telling you what you already know, but here is an example of what could cause this error:

+ Code Snippet

void A_Function(void);

//..... somewhere in your program

A_Function();//this will generate the error

this would fix the problem:

+ Code Snippet

void A_Function(void);

//..... somewhere in your program

A_Function();


//.... the function can be anywhere in your code
void A_Function(void){
//.....stuff here
}

So ultimately, you are missing the actual function (or at least your compiler can't find it)

The fastest code is the code never written.

Thanks for the clarification, Hawkblood. I've gotten around the error before but couldn't remember exactly what it was. As I say, I've only started in C++ a few weeks back. That's one more for the knowledge bank!

The last RC moved the function definitions previously declared in .h files to their own .cpp file so that include guards could be added to the header. Add simpleWindow.cpp and initDarkGDK.cpp to your project to fix this error.

Mistrel's suggestion worked for me and I was getting the same error. Has anything changed for you or is this still the same error message?

i do believe i setup this simple project according to the help file in the darkgdk 2 package. I however am still getting this error.

+ Code Snippet

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

and i don't understand why, I have these file in the stated directories that are in this error message so i am clueless, what am i doing wrong. I have included the .cpp files in the filter of the project like Minstrel said. I know c++, i learned it 20 years ago, but i seemed to have lost some knowledge along these past years. I have the bit about $(ProjectDir) in the proper place. it states that under the "active(win32)" section. I am running windows 7 64 bit, does that matter?

You will need to modify the includes in the files Mistrel mentioned.

Try:

+ Code Snippet

#include <include/puregdk/simpleWindow.h>
#include <include/puregdk/initDarkGDK.h>
