C++ Linker Error with DirectX SDK - c++

Question

I'm trying, desperately, to get into C++ programming with DirectX. It's been a steep uphill battle, and I've only written a couple of lines of code. Most of my battles have been with the linker. So far, I have this in my header file:
#pragma once
#include "resource.h"
#include <d3d11.h>
#include <d3dx11.h>
#include <d3dx10.h>
#pragma comment (lib, "d3d11.lib")
#pragma comment (lib, "d3dx11.lib")
#pragma comment (lib, "d3dx10.lib")
IDXGISwapChain *swapChain;
ID3D11Device *device;
ID3D11DeviceContext *deviceContext;
void InitializeDirect3D(HWND hWnd);
void CleanDirect3D(void);
And in the source file:
// InitializingDX.cpp : Defines the entry point for the application.
//
#include "stdafx.h"
#include "InitializingDX.h"
#define MAX_LOADSTRING 100
// Global Variables:
HINSTANCE hInst; // current instance
TCHAR szTitle[MAX_LOADSTRING]; // The title bar text
TCHAR szWindowClass[MAX_LOADSTRING]; // the main window class name
// Forward declarations of functions included in this code module:
ATOM MyRegisterClass(HINSTANCE hInstance);
BOOL InitInstance(HINSTANCE, int);
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);
// TODO: Place code here.
MSG msg;
HACCEL hAccelTable;
// Initialize global strings
LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
LoadString(hInstance, IDC_INITIALIZINGDX, szWindowClass, MAX_LOADSTRING);
MyRegisterClass(hInstance);
// Perform application initialization:
if (!InitInstance (hInstance, nCmdShow))
{
return FALSE;
}
hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_INITIALIZINGDX));
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))
{
TranslateMessage(&msg);

}
}
return (int) msg.wParam;
}
//

void InitD3D(HWND hWnd)
{
DXGI_SWAP_CHAIN_DESC scd;
ZeroMemory(&scd, sizeof(DXGI_SWAP_CHAIN_DESC));
scd.BufferCount = 1;
scd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
scd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
scd.OutputWindow = hWnd;
scd.SampleDesc.Count = 4;
scd.Windowed = true;
D3D11CreateDeviceAndSwapChain(NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, NULL, NULL, NULL, D3D11_SDK_VERSION, &scd, &swapChain, &device, NULL, &deviceContext);
}
It breaks on that last line, saying "error LNK2019: unresolved external symbol D3D11CreateDeviceAndSwapChain#48 references in function void_cdecl InitD3D(struct HWND__*)" (?InitD3D##YAXPAUHWND__###Z)".
I don't know what's wrong here, the #includes work to link the D3D libraries in, and the program builds or executes up until it gets to that line. Any help you guys could give would be appreciated. Thanks!

Answer 1

For some reason, if I omit the x64 library, it works. I don't know why.

Answer 2

What version of the DirectX SDK do you have? The latest up to date SDK can be downloaded from here .
Also, make sure you are linking to the correct library path. By default it is
C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86;$(LibraryPath)
I attempted to compile you code (I have to comment out the additional #includes that were unavailable, and had to #define some of the ID variables, and it was about to compile with no linker errors.

Answer 3

The first thing that comes to mind is that this function does not exist for Metro applications. If you are using the vNext preview versions, then the function will not be available.

Answer 4

It seems the d3d11 libs from older SDKs don't define this GUID. Here is a workaround in case you are not ready to switch SDKs yet...
Add the following lines to your code (in the cpp file where you need it)...
const GUID __declspec(selectany) IID_ID3D11Device = {
0xdb6f6ddb,
0xac77,
0x4e88,
{0x82, 0x53, 0x81, 0x9d, 0xf9, 0xbb, 0xf1, 0x40}
};

Answer 5

Try linking with DXGUID.LIB
#pragma comment (lib, "dxguid.lib")
You haven't mentioned which version of the compiler you are using. If you are using VS 2012 or VS 2013, then you need to take some extra steps to use old stuff like D3DX11 from the legacy DirectX SDK without getting weird errors. See Where is the DirectX SDK?. If you are using VS 2010 or later, you have to manually add the references to the DirectX SDK to your VC++ directories--it's not automatic.
You should take a look at the latest version of the Direct3D 11 tutorial (Win32 desktop version) on MSDN Code Gallery. You may also find DirectX Tool Kit useful, as well as the article Living without D3DX.
