extern class

[zorro68]

Hi. I want to define a global class variable. I have defined in my main.cpp this:
IDIOMA lang; //IDIOMA is the class name.
and then in other .cpp I have write:
extern IDIOMA lang;
I have no compiler error and no linker error, but when i used some member of lang is empty (lang.number for example).

What happend? How can I defined a global class variable that i can used in all modules of my programm?

Thanks

It looks like you do everything right. Did you remember to initialize lang? Do you have any other global variables or maybe static ones?

Or implement a singleton class.
