hello everybody,

could somebody be so kind to explain me why this happen with an gcc
compiler and what i'm doing wrong.

It makes no difference if i first compile question.cpp to question.o
and use gxx -o a.out tmp.cpp question.o instead.
same problem occur if using gcc under unix but with CC of silicon
graphics compilation ends successful. 

ciao olaf



file tmp.cpp:

  #include "question.h"

  void main(){
        question();
  }

file question.h:

  int question(void);


file question.cpp: 

  #include <iostream.h>
  #include "question.h"

  int question(void){
        cout << "everything seems to be ok!" << endl;
        return(0);
  }

command line:
  gxx -o a.out question.cpp tmp.cpp

error:
