Fatal error LNK1104: cannot open file ‘d3dc9.lib’

directxdirectx-9dlllinkervisual studio 2010

I'm currently going though a game programming book and am trying to compile some directx9 code

I have the latests DirectX11 SDK and the code has these lines of code

#pragma comment(lib,"d3d9.lib")
#pragma comment(lib,"d3dx9.lib")

But I get
LINK : fatal error LNK1104: cannot open file 'd3dc9.lib'

I don't know how to set it up to find this file although in fact I don't get why it asks for it since it isn't inside the Lib file for the DirectX 11 SDK and isn't what i've asked for.

The linker only knows the name of the .lib file, it doesn't know what directory it is stored in. Project + Properties, Linker, General, Additional Library Directories setting.

The version 11 SDK is quite new. You may need an older version of the SDK if these .libs are no longer distributed. I know the June 2010 edition has them. Download is here.

Visual-studio – Error ‘LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt’ after installing Visual Studio 2012 Release Preview

This MSDN thread explains how to fix it.

To summarize:

Either disable incremental linking, by going to

Project Properties 
   -> Configuration Properties 
       -> Linker (General) 
          -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"

or install VS2010 SP1.

Edits (@CraigRinger): Note that installing VS 2010 SP1 will remove the 64-bit compilers. You need to install the VS 2010 SP1 compiler pack to get them back.

This affects Microsoft Windows SDK 7.1 for Windows 7 and .NET 4.0 as well as Visual Studio 2010.

Did you actually define "C:\OpenCV2.2\lib\opencv_calib3d220d" as the input, or "C:\OpenCV2.2\lib\opencv_calib3d220d .lib"? (No space, can't bold/italics it without the space is why it's there.)

It needs to have that .lib there or it won't work. Even if it's complaining about a .obj

Also: Under Linker-> General -> Additional Library Directories you can put "C:\OpenCV2.2\lib\" and then you won't have to type out the directory each time you add something from that directory to Linker -> Input -> Additional Dependancies : You could just put "opencv_calib3d220d.lib", for example.
