unresolved external symbol "int __cdecl _.." between C and Cpp file

[leKoxn]

Hi all, I am receiving a

"error LNK2019: unresolved external symbol "int __cdecl _function(...)" error while trying to compile the following files:

main.cpp
--------------------------------------------
#include "function.h"


int main()
{

function(0, 0);

return 0;
}

---------------------------------------------


function.h
--------------------------------------------

#ifndef FNC_H
#define FNC_H

extern void function(int a, int b);

#endif
---------------------------------------------


function.c
--------------------------------------------

#include "function.h"

void function(int a, int b);
{
// do something here
}
---------------------------------------------



Seems like the program cannot find the function's definition. Why is that?
Am I missing something with the association .h -> .c ?

Please give me suggestions
