    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 errorexpected 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.
