I updated my macOS to Sierra, and some of my files vanished. The most important were Allegro's library. I am trying to install it again like the video (https://www.youtube.com/watch?v=UJtmJfWNTJY) which I saw the first time which I installed, but the follow error message has been showing:
'$Users/macbookpro/Downloads/allegro/include/allegro5/platform/alosx.h:43:12: fatal error:
'QuickTime/QuickTime.h' file not found'
#import <QuickTime/QuickTime.h>
I searched for it and I discovered that is just change parameters in Xcode, however, I am not using Xcode to compile my code, although terminal. Any hint?
