Ok, I know how to use static libraries, but Dynamic Libraries ... ehhhhh I'm lost. Do I need to tell the compiler to link it or is all loading and linking done in h3dInit? And are the only H3D files I need to compile into my program Horde3D.h and Horde3DUtils.h or do I need to include everything else as well?

Main question is this, how in the hell does that all work?

It depends on the OS you're using :?

On windows, when you compile Horde it produces a .lib and a .dll

When you compile your game, you include Horde3D.h and you link to the LIB file (just like with a static library). The DLL file must be placed alongside your EXE in order to run your game.

Alright, and Windows is all I am concerning myself with for now. For the record, what about Linux and Mac?

Also, I'd like to post a log of the compile I did only because I find Warnings irksome for some reason.

Might want to keep that "NOMINMAX" define warning in mind for the next version.

Well, linux behaves a bit different with shared libraries (they are called .so instead of .dll here):
You don't need any .lib, you link directly to the .so, and usually the shared object is then placed in some special path (/usr/lib or /usr/local/lib), if you want to put it next to your application, you have to compile it with a rpath directive. CMake e.g. does this automatically.

Oh, MinGW btw usually does not create a .lib, it creates a .a

And about the warning:
This should fix it (to appear soon in my horde3d hg repository -.-):

That go in Horde3D.h?

No in utOpenGL.h. See:

Post subject:  Re: DLL Confusion
If I've read that patch right, it means

Open up utOpenGL.h

Remove:
# define NOMINMAX

And replace it with:
# ifndef NOMINMAX
# define NOMINMAX
# endif
