Thanks for the help guys! This case is a bit more boring, (day 15, IO) at the point where I stopped, Casey made declaration of 3 functions in handmade.h file. However, the definition was made in win32_handmade.ccp file. I figured the DLL solve this problem, but from what I understand, the DLL is a future issue yet.
Does anyone remember how did you solve this problem of delaration in handmade.h and definition in the win32_handame.h file ??
PS. by curiosity, I uncompressed day 88 sources files in the project directory provided by kirbasin, and it worked perfectly!
