Thread: typedef problem

Hello, I have 3 header files and 1 .c file.

The .c file #includes both header files.

In the 2 header files, there are extern definitions of of a struct:

header1.h:

Code:

#include "types.h"

extern struct a
{
     mytype a;
     ....
} myStructA;

header2.h:

Code:

#include "types.h"

extern struct b
{
      mytype b;
      .....
} myStructB

types.h

Code:

typedef int mytype;

mycfile.c

Code:

#include "header1.h"
#include "header2.h"

struct myStructA;
struct myStructB;

int main()
{
   ....
}

My issue is that gcc keeps complaining about a redefinition of typedef mytype. I understand what this means since I #include types.h in both headers. I need to do this since both headers use mytype in their stucts. Is there any way around this?

Use inclusion guards.
