Thread: Header file error

I'm using a makefile, but anyways this is my struct.h file

Code:

#ifndef struct
#define struct

typedef struct person{
    char *name;
    int socialNum;
    char *dateOfBirth;
}person_t;

typedef struct flights{
    char *flnum;
    char *from;
    char *to;
    char *date;
    float price;
    person_t *fPerson;
}flights_t;

#endif

And this is my error from the terminal:

Code:

gcc -Wall -c bookAFlight.c
In file included from bookAFlight.h:7:0,
                 from bookAFlight.c:1:

 typedef struct person{
                      ^
struct.h:8:2: warning: data definition has no type or storage class
 }person_t;
  ^~~~~~~~

struct.h:10:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token

 }flights_t;
  ^~~~~~~~~
struct.h:17:2: warning: type defaults to ‘int’ in declaration of ‘flights_t’ [-Wimplicit-int]

Now I dont see whats wrong with my struct.h file tbh, if anyone can point it out.
Thanks.

Eh. Never use a reserved word as a header guard name. Change this:

Code:

#ifndef struct
#define struct

To something like this:

Code:

#ifndef STRUCT_H
#define STRUCT_H
