Bullet Physics, Linking Error in Visual Studio

Question

I'm using Bullet Physics, on Windows 7 and Visual Studio 2012. I have compiled the libraries, and the demos are working fine, but when I try to create my own solution, I am getting linking errors. I have minimised the amount of code to

#include "btBulletDynamicsCommon.h"
int main(int argc, char*argv[])
{
    btBoxShape* box = new btBoxShape(btVector3(1, 1, 1));
    return 0;
}

Which when I link, using Visual Studio gives me the following Errors:

1>------ Build started: Project: HelloBulletApp, Configuration: Release Win32 ------  
1>  main.cpp  
1>  main.obj : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG;   add /LTCG to the link command line to improve linker performance

1>c:\path\to\HelloBulletApp\HelloBulletApp\Release\HelloBulletApp.exe : fatal error LNK1319: 6 mismatches detected

The same errors are appearing when I build in Debug or Release Mode. I've tried:
- rebuilding bullet 2.81,
- redownloading 2.81,
- creating a blank project and adding the libraries,
- creating a blank project and adding the Projects as suggested at http://bulletphysics.org/mediawiki-1.5.8/index.php/Creating_a_project_from_scratch, but to no avail.

Is there anything I can do?

It looks like BulletCollision.lib was compiled to link with the DLL version of the C runtime library (/MD), but you're compiling to link with the statically linked runtime library (/MT). Change your compiler options to link with the DLL runtime library.
