Hello all,

I have switched from Visual Studio 2008 to Visual Studio 2013. I have two different Allegro projects saved. One of them opens and compiles without issue, the other does not. The one that doesn't compile gives me the following:

Error 1 error C2632: 'char' followed by 'bool' is illegal c:\allegro5\include\allegro5\platform\astdbool.h 26 1 mm
Warning 2 warning C4091: 'typedef ' : ignored on left of 'unsigned char' when no variable is declared c:\allegro5\include\allegro5\platform\astdbool.h 26 1 mm

The section of code that the compiler is erroring out on is from astdbool.h:

#SelectExpand
  1#ifndef __al_included_allegro5_astdbool_h
  2#define __al_included_allegro5_astdbool_h
  3
  4#ifndef __cplusplus
  5#  ifdef ALLEGRO_HAVE_STDBOOL_H
  6#     include 
  7#  else
  8#     ifndef ALLEGRO_HAVE__BOOL
  9         typedef unsigned char _Bool; // this is the line the errors reference
 10#     endif
 11#     define bool _Bool
 12#     define false 0
 13#     define true 1
 14#     define __bool_true_false_are_defined 1
 15#  endif
 16#endif
 17
 18#endif

Has anyone encountered this before?

I had the same.

It's because (I think) VC13 has stdbool.h and older versions don't.
I fixed it by editing include/allegro5/platform/alplatf.h and changing the line

/* #undef ALLEGRO_HAVE_STDBOOL_H */

#define ALLEGRO_HAVE_STDBOOL_H

If you're compiling from source I think you can edit alplatf.h.cmake - not sure about that.
