gcc -c main.c In file included from main.c:1: Getting Error: expected specifier

[ypankaj]

Hi,

I am writing simple program, which includes .h file which having structure defined as like this:
-----------------------------------
/* main.h */
#ifndef _MAIN_H_
#define _MAIN_H_ 1
void Rules();
typedef struct _CRules{
int var1;
char *var2;
bool var3
} CRules;
#endif
------------------------------------
while compling my main.c i'm getting this error
$gcc -c main.c
In file included from main.c:1:
main.h:11: error: expected specifier-qualifier-list before ‘bool’

why this ??

Thanks,

Two problems.

1. It would be best to put a semicolon (";") at the end of the var3 line.
2. Have you actually defined the bool type anywhere?

Hope this helps.

Thanks Bill,

(1) I putted ";" at end of var3. But the same problem.
(2) In code, I havn't defined anywhere bool
my problem is, when i remove bool it compiles successfully, only bool is not working..

One solution is to use int instead of bool.

[khlitoshi]

the type bool doesn't exist in C, you have to define it first or use unsigned instead.

Include the file stdbool.h file to your program. Thats it. In some version of GCC bool is defined in this file.
