Linker Error with use of stl map?

You have declared loadedSurfaces but you have not defined it. You need to add the following to exactly one translation unit to actually declare the variable.

CSurface::loadedSurfaces is declared but not defined. Add the following to the . Cpp file.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
