c - error: dereferencing pointer to incomplete type -> passing structure to module -


the structure:

    #include <gtk/gtk.h>     #include "db_interface.h"      struct addnewemployee {     const gchar *fname;     const gchar *lname;     };      void new_emp_get_data(gtkwidget *widget, gpointer add_emp_window)     {       struct addnewemployee n_e_s; //new employee struct        <gtk portion removed clean code>         n_e_s.fname=gtk_entry_get_text(gtk_entry(first));       n_e_s.lname=gtk_entry_get_text(gtk_entry(last));        db_add_new_emp(&n_e_s); //pass struct db_interface add new employee     }

the header file (db_interface.h)

    #ifndef db_interface_h     #define db_interface_h      struct addnewemployee *n_e_s;     void db_add_new_emp(struct addnewemployee *n_e_s);      #endif

the second module (db_interface.c)

    #include <stdio.h>     #include "db_interface.h"      void db_add_new_emp(struct addnewemployee *n_e_s)     {       printf("greetings db_interface, %s\n", n_e_s->fname);     }

when try compile code using gcc, message "error: dereferencing pointer incomplete type". have tried several different answers found when others posted problems error, have yet find 1 works. copied code in function db_interface.c module original module - 1 containing struct - , worked fine, know problem lies sending structure db_interface.c module.

just move struct addnewemployee db_interface.h , should compile fine. both .c files need know how struct implemented.
