Thread: Problem w/ porting and static...

I've run into a problem trying to port a program of mine from C to C++, I am using MSVC++.

Code:

Controller.obj : error LNK2001: unresolved external symbol "private: static struct Color (*  PixelBuffer::myPixelBuffer)[512]" (?myPixelBuffer@PixelBuffer@@0PAY0CAA@UColor@@A)

Code:

#ifndef PixelBuffer_h
#define PixelBuffer_h

#include "Types.h"

class PixelBuffer {
private:
	PixelBuffer () {}; // Can't create one.
	static Color myPixelBuffer[512][512]; // <-- Error here

public:
	static void put (int x, int y, Color color) {PixelBuffer::myPixelBuffer[x][y] = color;}
	static void display (
		void (*initialize) (int width, int depth),
		void (*process) (int x, int y, Color color),
		void (*finalize) (void))
	{
		
		int i, j;
		initialize (512, 512);
		for (i = 0; i < 512; i++) {
			for (j = 0; j < 512; j++) {
				process (i, j, myPixelBuffer[i][j]);
			}
		}

		finalize();

		return;
	}
}; // End class PixelBuffer

#endif

Code:

/*
typedef struct {
	int red;
	int green;
	int blue;
} Color;
*/

struct Color {
	int red, green, blue;
};

Now, I'm a little stuck. I don't suppose anyone knows the remedy to this problem?

It doesn't matter whether I use the typedef, or the C++ style struct.

Also, maybe I should have mentioned this, that last code block is a snippet from Types.h

Thanks Sorensen. Creating a PixelBuffer.cpp with this made it work:

Code:

#include "Types.h"
#include "PixelBuffer.hpp"

Color PixelBuffer::myPixelBuffer[512][512];
