I have followed the build instruction for Box2d TO THE LETTER

I built all of the libs and i have linked them into my program but i still get these errors

I am not sure why. I have looked through everything.

I am using vc++ 2010 express.

please help me out with this
thanks,
dartos

I got the same problem, but have no solution yet

You might be building some projects against the system DLL and others against the static system library. Make sure the project settings are consistent.

Bumping an old thread with the same request. The only errors I'm getting are the one's of this nature:
.
How do I change the "debug level" of the Box2D.lib?

I think this is caused by compiling your code as 'release' and then linking to a 'debug' library, or vice versa.

Yeah, that's what my research has turned up, but I only have one library for Box2D. I mean, my other libraries for SFML come with both debug and release versions.

The Box2D project does not distribute binaries, only source.
