strange warnings

[stromhau]

Ok, i have a file with main and an additional .cpp file i include in the main file but i get a lot of strange warnings when including. Both files compile just great separately. It seems that it have something to do with the inclusions of header files.

Here are the files i include in main.cpp file
#include "SDL.h" // SDL: window & input library
#include "SDL_opengl.h" // platform independent OpenGL include
#include "Polygonstruct.cpp"
#include <stdio.h>
#include <stdlib.h>

Polygonstruct is my other class file and have these includes

#include <vector>
#include <iostream>
#include <fstream>
#include <string.h>
#include <math.h>

Any suggestions ?
Tommy,

cpp files should really be included, it is bad form. You should compile the second cpp file and then link the 2 files together.

cc -c 1.cpp
cc -c 2.cpp
link 1.obj 2.obj
