I have had that same question, and the answer is this-
When you start a program, it always starts out with
#include "darkGDK.h"
The darkGDK.h is a header file and if you go to your programs menu-(this is where mine is)- C:\Program Files\The Game Creators\Dark GDK\Include
You should see that file there. Open it, and it says
#include DarkSDK.h, so go to that file. In that file is has things like
#pragma comment ( lib, "darksdk.lib" )
which is the lib file. go to C:\Program Files\The Game Creators\Dark GDK\lib
and you will fine the lib files. If you want to know how to write lib files-- your guess is as good as mine!
I would figure it out, but I dont have anything that can read lib files, other than my notepad thing-- but that comes up really strange looking.
~~Its not about what you know, its about how you figure it out.~~
