warning: initialization from incompatible pointer type

Question

I'm completely stuck at this point. I have the following code:

typedef void    (*TPFN_ACC)(void); 
typedef char    (*TPFN_EVE)(void); 


typedef struct {
  int           idDestino;            
  char        * nombre;         
  TPFN_EVE      evento;         
  TPFN_ACC      accion;        
} TRANSICION;

And then I do this:

TRANSICION transiciones_Stopped[] = {
    {UPLEFT, "t_Stopped_to_Up_Left", ev_up_left, acc_up_left},
    {0, 0, 0, 0}
};

And I'm getting this warning:

warning: initialization from incompatible pointer type

Could you please help me?

Thanks in advance.

Answer 1

You have this:

void ev_up_left();
char acc_up_left();

and in your TRANSICION structure, member evento of type char (*)(void) is initialized with ev_up_left of type void (*)(void) .

Same for member accion of type void (*)(void) initialized with acc_up_left of type char (*)(void) .

You probably swapped the two types / two structure members by mistake.

Answer 2

change

typedef void    (*TPFN_ACC)(void); 
typedef char    (*TPFN_EVE)(void);

to

typedef void    (*TPFN_EVE)(void); 
typedef char    (*TPFN_ACC)(void);
