Question

I am working on an older project that still has the deprecated “#include iostream.h” inclusions. I understand that iostream.h is deprecated and should not be used, but some of the systems that this code has to run/compile on are old solaris machines running CC and do not have iostream available. My question is: how can I make my more modern g++ compiler accept the iostream.h inclusions.

EDIT: The compilier cannot find the iostream.h file so I am assuming that none of the .h versions of the library are available to g++.

I’d take a step back and write another intermediate header you use everywhere instead that does something like:

#if defined(sun) || defined(__sun)
# if defined(__SVR4) || defined(__svr4__)
/* Solaris */
#include <iostream>
# else
/* SunOS */
#include "iostream.h"
# endif
#else
/* Sane, modern system */
#include <iostream>
#endif
