[Dev-C++] $_70 wierdness!

[<ste...@ge...>]

Hi guys!

Anyone know what this means?

f:\development\opengl\sengine v2.5\scenes.o(.text+0xcf):scenes.cpp: =
undefined reference to `$_70::load(char *, char *)'
f:\development\opengl\sengine v2.5\scenes.o(.text+0x1e0):scenes.cpp: =
undefined reference to `$_70::draw(bool, bool)'
f:\development\opengl\sengine v2.5\scenes.o(.text+0x277):scenes.cpp: =
undefined reference to `$_70::free(void)'

And can someone please explain me what it is with headers? Although I've =
been programming for several years, I'm still confused about what goes =
in a *.h-file and what goes into a *.cpp.
To me it seems kinda like the only difference, is that it takes longer =
to compile if stuff is saved as .cpp-files instead of header files, but =
I can't believe that's it :/

Thanks!!!
