错误的LNK2001和LNK2019 [英] Error's LNK2001 and LNK2019
问题描述
我随同Frank D Luna一书使用DirectX11进行3D游戏编程介绍一书。当我尝试和构建我的项目时，我得到这些错误。

我必须获得
在VS2013中修复它，并且重新生成它，
RE：D3D11CreateDevice
您需要将 d3d11.lib 添加到链接库依赖。一个简单的方法是添加到您的.cpp源：
#pragma comment（lib，d3d11.lib ）
RE：D3DX11CompileFromFileW，D3DX11CreateTextureFromFile，D3DX11CreateShaderResourceViewFromFileW
$ b
D3DX11已弃用，不是内置在VS 2013中的Windows 8.1 SDK的一部分。请参见 DirectX SDK在哪里？
删除 #include< ; d3dx11.h> 和 d3dx11.lib 。
从您的链接库依赖项添加 #include< d3dcompiler.h> 和 d3dcompiler.lib 。
不要使用 D3DX11CompileFromFileW ，请使用 D3DCompileFromFile 。
效果11 的最新版本 D3DX11CreateEffectFromFile 可以替换 D3DX11CompileFromFileW 和 D3DX11CreateEffectFromMemory 你在那里做什么。您可以通过NuGet for VS 2013 Win32桌面应用程序（ fx11_desktop_2013 ）将Effects 11添加到您的项目。
使用DDSTextureLoader函数代替 D3DX11CreateTextureFromFile 和 D3DX11CreateShaderResourceViewFromFileW CreateDDSTextureFromFile 或 CreateWICTextureFromFile 从 DirectX Tool Kit 。您可以通过NuGet for VS 2013向您的项目添加 DirectX工具包（ directxtk_desktop_2013 ）。
RE：DXTraceW
c $ c> dxerr.cpp 和 dxerr.h 来自此帖子并将其添加到您的项目中。
I am following along with the book "Introduction to 3D Game Programming with DirectX11" by Frank D. Luna. And I am getting these errors when I try and build my project.

I had to get the source for the Effects11.lib and rebuild it for VS2013, and I have everything included and linked that I know of. Not sure how to fix these.
RE: D3D11CreateDevice
You need to add d3d11.lib to your link library dependencies. An easy way to do that is to add to your .cpp source:
#pragma comment(lib,"d3d11.lib")
RE: D3DX11CompileFromFileW, D3DX11CreateTextureFromFile, D3DX11CreateShaderResourceViewFromFileW
D3DX11 is deprecated and is not part of the Windows 8.1 SDK which is built into VS 2013. See Where is the DirectX SDK?.
Remove #include <d3dx11.h> and d3dx11.lib from your link library dependencies.
Add #include <d3dcompiler.h> and d3dcompiler.lib from your link library dependencies.
Instead of using D3DX11CompileFromFileW, use D3DCompileFromFile.
The latest version of Effects 11 has D3DX11CreateEffectFromFile which can replace both D3DX11CompileFromFileW and D3DX11CreateEffectFromMemory since that's probably what you are doing there. You can add Effects 11 to your project via NuGet for VS 2013 Win32 desktop apps (fx11_desktop_2013).
Instead of D3DX11CreateTextureFromFile and D3DX11CreateShaderResourceViewFromFileW, use DDSTextureLoader functions CreateDDSTextureFromFile or CreateWICTextureFromFile from DirectX Tool Kit instead. You can add DirectX Tool Kit to your project via NuGet for VS 2013 (directxtk_desktop_2013).
RE: DXTraceW
Get the latest dxerr.cpp and dxerr.h from this post and add them to your project.
