I have downloaded Box2D and I have CMake and MinGW. How can I compile the Box2D libraries with MinGW?

According to their info, you must run cmake with the following parameters:

-DBOX2D_INSTALL=ON -DBOX2D_BUILD_SHARED=ON

Then, run make.

Do I have to compile it to use them? I tried including all the CPP files, but I get many undefined references.

I think you meant that you included all the .h files

Yes, indeed, you should compile and link against the resulting .lib file to get rid from the undefined references.

Note that I didn't compile this library. Ever. I'm just reading the (lame) instructions it included in the zip file.

Also, I have not been able to compile it yet. I run CMake then make and all I get is more makefiles.

Oh yeah, it also says that after running make once, you have to run make install

If you want to compile the entire Box2D library into your application (without needing the libbox2d.so), you'll need to do

export b2d='/dir/to/box2dsource'
g++ -I$b2d $b2d/Box2D/Common/*.cpp $b2d/Box2D/Rope/*.cpp $b2d/Box2D/Collision/*.cpp $b2d/Box2D/Dynamics/Contacts/*.cpp $b2d/Box2D/Dynamics/Joints/*.cpp $b2d/Box2D/Dynamics/*.cpp $b2d/Box2D/Collision/Shapes/*.cpp your_application.cpp

This allows for portability
