Linker error with DirectX C++

Question

I'm working on a Direct X11 project, and i am trying to draw a rectangle in the window i generated (the whole window directX initialization did work fine, since it compiled correctly before). For this, i included the following headers :

#include "CommonStates.h"
#include "SpriteBatch.h"

I added the link of these headers to the C/C++>General>Additional Include Directories, and i think it did find it since i have no errors about including it.

After, i tried to compile my project. The following lines caused some linker errors :

RECT *try1 = new RECT();
try1->bottom = 0; try1->left = 0; try1->right = 50; try1->bottom = 50;

CommonStates states(d3dDevice);
sprites->Begin(SpriteSortMode_Deferred, states.NonPremultiplied());
sprites->Draw(textureRV, XMFLOAT2(50, 50), try1, Colors::Black);
sprites->End();

Errors :

I figured these are some linker errors, so i added the path of the DirectXTK.lib file to Linker>General>Additional Dependencies. I did not find the CommonStates.lib nor the SpriteBatch.lib files though, even if i compiled the DirectXTK-master project, the only lib generated is DirectXTK.lib.

Hence, i added DirectXTK.lib to the Linker>Input>Additional Dependencies. But then, i still the following errors :

1>DirectXTK.lib(CommonStates.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in AddForceMessage.obj
1>DirectXTK.lib(CommonStates.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in AddForceMessage.obj

1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library

So I really do not understand what it means, could you please tell me what i did wrong and what i should do to make it work please ? Thank you very much.

Answer 1

mismatch detected for '_ITERATOR_DEBUG_LEVEL'

This means the library you're linking to was built in a different configuration (Debug or Release) than the one used to build your current program.

Steps to fix:

1. Build the library both in Debug and in Release. You will get a DirectXTK.lib file for each of those (in different directories).
2. In your main program, choose Debug as the build configuration, go to Linker>Input>Additional Dependencies and add the Debug DirectXTK.lib file you just built. Make sure you add the directory where the DirectXTK.lib file is to VC++ Directories>Library Directories.
3. Repeat step 2 for Release mode. Make sure you're changing these configuration properties only for one configuration at time.

Now whenever you'll build your program in Debug mode, it will be linked to the Debug library, and same for Release.
