typedef may be undeclared or ambiguous

In a header file I have a single struct:

#ifndef _MY_STRUCT_
#define _MY_STRUCT_
struct myStruct{
   char c1[1];
   char c2[10];
   char c3[10];
}

typedef myStruct MYSTRUCT;
#endif

And in another header file this struct:

#include "my_struct.h"
struct another_struct{
    int val1;
    MYSTRUCT strct;
};

When I compile this code I receive the following message:

The text "strct" is unexpected. MYSTRUCT may be undeclared or ambiguous.

For me both structures are fine. I can't understand why compiler is complaining about this.

Thanks for help.

here's how i think it should be done

#ifndef _MY_STRUCT_
#define _MY_STRUCT_
typedef struct {
   char c1[1];
   char c2[10];
   char c3[10];
} MYSTRUCT;

#endif

and the other file stays the same.

You should have gotten an error for the typedef as well, as you're missing the struct keyword there. It should be

typedef struct myStruct MYSTRUCT;
//      ^^^^^^
// Note the `struct` keyword here

And the missing semicolons at the end of the structures doesn't make the compiler any happier.
