Compiling Programs 2

This section will tell you how to compile a program using the Tools.h++ Class

Library.

2.1 Porting considerations

All of the Tools.h++ header ﬁles have lower-case names of less than eight

characters (plus sufﬁx) for ease of porting between MS-DOS and UNIX. The

sufﬁx is always "

Standard C++ library include ﬁles (such as

<iostream.h>

) deserve a special

comment. Most manufacturers have followed the AT&T naming convention,

but a few have chosen to go their own way. The most common difference is in

the sufﬁx. AT&T uses

".h"

, other manufacturers use

".hxx"

, or

".hpp"

The most common place where this creates a problem is in the iostream library.

You can increase your portability by always including

(instead of, for example,

<iostream.h>

). This header ﬁle will make the right

choice depending on which compiler you are using.

Sufﬁces for ﬁles containing code is also a problem. Consider the following

simple program called "

tes

t":

#include <rw/rwdate.h>

#include <rw/rstream.h>

main()

{

// Construct a date with today’s date:
