cannot open source file "DarkHelp.hpp"
I did all steps from readme_windows.txt, generated a Visual Studio solution, but when I build it I see this:
cannot open source file "DarkHelp.hpp" D:\Projects\DarkHelp\src-lib\DarkHelpConfig.cpp

How to fix it?
Did you delete it?
File is there: https://github.com/stephanecharette/DarkHelp/tree/master/src-lib
I just followed the instructions, that means I did not deleted any items. Is there any way to make it work?
Yes, it works for everyone else, including me. I would say you need to carefully follow the instructions. If you don't have that file, then my next question would be: why did you delete it? And if you don't have it, then I would clone the repo and start over cause you did something wrong.
