I am getting this particular error: `filename' undeclared (first use this function) and it points to the filename.c_str() ); area of the code, as well as a few others listed in the compile log. I'd like to also investigate the "apply_surface" not being recognized as well. I have included the following headers:

Any suggestions or advice would be greatly appreciated. I'm yet another newbie to the whole C++ scene, but this is more of a learning experiment than anything else.
