D3DXCreateTextureFromFile Craziness: External Errors with DIRECT X

[arcaine01]

So...I may be trying to do something strange; Please correct me if I am.

First I present my error:
error LNK2019: unresolved external symbol _D3DXCreateTextureFromFileA@12 referenced in function"public: __thiscall Texture::Texture(char const*)"



The DIRECT X 9.0 method constructor is written as follows:

D3DXCreateTextureFromFile (LPDIRECT3DDEVICE9 pDevice, LPCSTR pSrcFile, LPDIRECT3DTEXTURE9 *ppDevice)

LPDIRECT3DDEVICE9 is a pointer to the IDirect3DDevice9 interface.
LPCSTR is a long pointer to a constant string.
LPDIRECT3DTEXTURE9* is a pointer to a pointer to the IDirect3DTexture9 interface.

I populated the method with the following:

D3DXCreateTextureFromFile(GraphicDevice::GetService()->Device(), TEXT("Panel1.png"), &tex);

The function is contained in the constructor of my "Texture" class constructor.

#ifndef _TEXTURE_H_
#define _TEXTURE_H_
#include "graphicdevice.h"
#include <string>
class Texture
{
public:
	Texture(LPCSTR filepath);
	~Texture(void);
private:
	LPDIRECT3DTEXTURE9 Image;
};
#endif

graphicdevice.h contains the headers and class needed.

#ifndef _GRAPHIC_DEVICE_H_
#define _GRAPHIC_DEVICE_H_
#include <windows.h>
#include <windowsx.h>
#include <d3d9.h>
#include <d3dx9.h>
#include "window.h"
#include "singleton.h"
#pragma comment (lib, "d3d9.lib")
class GraphicDevice : public Singleton<GraphicDevice>
{
public:
	GraphicDevice(Window window);
	void Dispose();
	void Draw();
	D3DPRESENT_PARAMETERS DeviceInfo() {return _DeviceInfo;}
	LPDIRECT3D9 Interface() {return _Interface;}
	LPDIRECT3DDEVICE9 Device() {return _Device;}
private:
	D3DPRESENT_PARAMETERS _DeviceInfo;
	LPDIRECT3D9 _Interface;
	LPDIRECT3DDEVICE9 _Device;
};
#endif

I am having quite a large amount of trouble finding the cause for this particular external error that is occuring in the texture.obj file....does anyone know what could be the cause for this problem?

Usually "unresolved external" means "didn't link in the .dll". I would look there first.

[arcaine01]

I included and attached all of the proper files, and quadruple checked - just to be sure. I feel that the error lies in the way I am passing in the Device, or in the way I am passing in the string to the function.

Any ideas?

[tabstop]

If there was a difficulty in what you pass, you would get a compile error. Yet you don't.

MSDN says that that function resides in d3dx9.lib.

Wow, good call! Thank you very much for your assistance!
