Hi,

I can't get the c++ stream io implementation of the 0.98 linux SLS
distribution
working.

The following program(cout.c):

#include <iostream.h>
main(){
cout << "Hello World!\n";
}

fails to compile (g++ cout.c) with the following message:


cout.o: Undefined symbol _cout referenced from text segment
cout.o: Undefined symbol operator<<(ostream &, const char *) referenced
from
text segment

Can anyone explain why this happens? All other c++ appear to be
working.
ps while I'm on is there a "dissambler" program for linux?
