I just started a new project, and I have two files, main.cpp and functions.cpp. Main.cpp has all the normal GDK stuff and functions.cpp contains movement, loading of media, and other functions I will make. When I compile I get this happens:

Any ideas? It seems to be a DarkGDK issue.

You'll have to post code for us to help.

Here is my main.cpp:

+ Code Snippet

#include "DarkGDK.h"
#include "functions.cpp"

void DarkGDK()
{
	// Startup
	dbSyncOn();
	dbSyncRate(60);

	// Load Media
	loadMedia();
	
	// Game loop
	while (LoopGDK());
	{
		// User Input
		userInput();

		// Redraw Screen
		dbSync();
	}

	// Exit
	return;
}

And my functions.cpp

+ Code Snippet

#include "DarkGDK.h"

void loadMedia()
{
	// Weapon - Aug
	dbLoadObject("media\\models\\aug\\hud.x", 101);
	dbRotateObject(101, 0, -180, 0);
	dbLoopObject(101, 21, 47);
	dbLoadImage("media\\images\\aug\\crosshair.png", 102);
}
void userInput()
{
	// Fire if left mouse is clicked
	if (dbMouseClick() == 1)
	{
		dbLoopObject(101, 72, 75);
	}
	// Zoom if right mouse is clicked
	if (dbMouseClick() == 2) 
	{
		// Declare Variables
		int iGunZoom;

		// Zoom
		if (iGunZoom = 0)
		{
			dbSetCameraFOV(0, 25.0f);
			iGunZoom = 1;
		}
		else
		{
			dbSetCameraFOV(0, 62.0f);
			iGunZoom = 0;
		}
	}
}

But the other parts still happen.

I solved it by removing the directories of a different version of DirectX SDK, and keeping the August 2007 version.

functions.cpp should be functions.h. Not just for good practice, but so that the compiler will only produce a copy of the functions in one object. That way the linker will work properly.

Thanks, that did it. I still get this warning though:

That would be another linker option that needs changing. It should be fine for now, though, as long as it compiles.

It does compile fine, so I guess I will just leave it alone.

Go to Project Properties, and check under Linker->Input. For me, the ignore specific libraries option is set to "libcmtd, msvcrt, atls". That may help.

LIBCMT was the one that did it for me, works like a charm. Now only if the game would....
