extern function link error 2005

hey i'm really not sure how to solve this, im making a simple "press enter to continue" function called wait(), defined it in a header file with extern keyword, and then in the main file prototyped it and from then on used it as wait();

But it still states that the object is included in other files... halp plz?

//header file definition 

extern void wait(void)
         {
          char c = getchar();
          while (c != '\n')
            c = getchar(); }

and here's tjhe main file snippet....

//main cpp file
//including stuff..


// prototype
void wait(void);

// then use as 

wait();

why doesn't this work?

wait i phrased that wrong, what it says is that the functions is already defined in other objects, which are other cpp files in the same project.... error LNK2005

if it helps this is the actual error code given to me:

1>Compiling...
1>GameCore.cpp
1>Linking...
