My guess is you have something as follows...

#include "user_common.h"
main
{
  foo();
}

void foo(void)
{
 // Do something
}

Try adding a function prototype for foo() to your user_common.h file.

void foo(void);

From this article

A declaration or prototype is a way of telling the compiler the data types of the any return value and of any parameters, so it can perform error checking.

Essentially your compiler is complaining that you're using a function that it doesn't know about.
