Sharing Variables in C++ from a main.h

[pspballer07]

I need some help! I converted rpg paradise from C to C++ and then I got 'multiple definition' errors. I tried changing the vars to 'static' vars but then they don't share the var, they just each get their own of that var.

So how do I declare a var that will be shared amoung different c++ files from a header file? So say main.h had this

int i;

and main.cpp had this somewhere:

i = 211;
if(i == GetVar()){ printf("This is what I want."); }

and another C++ file had this:

int GetVar()
{
        return i;
}

and both C++ files included the main.h

I found the solution, I had to use extern, mods can delete this thread

extern i = 211;
if(i == GetVar()){ printf("This is what I want."); }

Could you give one reason why you dont ask help in the c/c++ help thread???

**** off! Stop antagonizing every single person who asks a question!

Why do you make flashers?
Do you know you are hated by the entire PSP-Programming community?
Do you honestly think you have any right to ask a question?
What makes you better than anyone else?
Could your damn ego be any bigger?

Instead of being an ******* and repeating yourself to the same people with the same question, why don't you go ahead and answer those questions for me?

Here, I'll give you a hint on one of them. No one gives a **** what you think or what you say, so you have no right to be saying anything to this kid.

I'm telling you right now, we have been wanting to do this for a very long time. We don't want you here.

Stop acting like you're the boss.

Anyways, external variables aren't C++ specific, so going from C to C++ shouldn't have changed anything, nor been necessary.

Usual practice is to put:

extern int foo;

into foo.h, and put:

#include "foo.h"
int foo = 0;

into foo.c, and put:

#include "foo.h"

into all the other .c files that need to access the variable "foo".
Including foo.h in foo.c allows the compiler to check the declaration in
foo.h against the corresponding definition in foo.c to ensure that they
match.
