problem with structure !!!!

Hello all
I've wrote this header file

Code:

---

struct sign
{
    char sign;
}signlib;

struct identifier
{
    char *variable;
    double number;
    struct identifier *id;
}identify;


struct lib
{
    char hash;
    char *include;
    signlib sign1;
    identify lib_name;
    char dot ;
    char h;
    signlib sign2;
};

---

and when I compiled it i have this error message :

PHP Code:

---

tree.h:18 error: expected specifier-qualifier-list before signlib 


---

can any one tell me what is the problem ???
thanks.

The compiler does not have enough information, that is the problem.

You should try something like these:

Code:

---

typedef struct signlib
{
    char sign;
}signlib;

---

adrian2009's suggestion looks correct. The problem is that in the original example, signlib is a variable of type struct sign.
