.-I NEED help!... In my DDraw wrapper I have CDirectScreen class and CDirectSurface class. As there will be MANY CDirectSurface objects I NEED some of its members(variables) to be static: That means that just ONE copy of that variable is used for every object of that class. .-I do: private: static _var; public: static void SetVar(TYPE var) {_var=var;}; static TYPE GetVar() {return _var;}; .- This way I get linking errors. I´ve tried to do the assign this way: CClass::_var=value; ,but I get the same error. .- PLEASE HELP!!! .-Thank you very much for your help... What the hells!

quote:
private:
static _var;

You forgot to put a type declaration in there . You''ll need something like int, char, float, etc.

.- The Senshi : Of course In the real code var has a type, that was just pseudocode! I get a linking error, not a compiling error...

.-Please help!



What the hells!

What''s the exact linker error?


Give me one more medicated peaceful moment.

Why don''t you post the real code, then, so we can take a look at it?

You need to actually declare the static variables elsewhere in code, not just in the class. I don''t know why... but oh, well!

    class Dinglehopper{   static int fork;};int Dinglehopper::fork;    

At least, that''s what worked for me. There might be a different way.

I like food.

You have to declare them in code like this:

// Header file

class Foo
{
static int fooVar;
}

// Source file
int Foo::fooVar = 0; // or whatever you want it to start at




The reason for this is because the static variables are basically globals with class scope (I know that kinda doesn''t make sense ) but they need to be declared as actual variables somewhere, because they don''t belong to any actual structure/class object, just to the scope of the class.

.- Thank you men(or women...)!

.-That was it!. I knew that to initialize a static class variable I have to put CClass::Variable=INITIALIZING_VALUE...
But as I didn´t need to initialize it to 0/NULL I wasn´t doing it...

.-Sorry for the delay in answering, although at work I have Internet and I´m posting messages here these days, I couldn´t try this at the program...

.-Thanks again...

What the hells!
