<h3>Installing the Downloaded Version</h3>
Digital Mars has a different view of installation than most software products.
It doesn't need registry entries, environment variable settings, nor does it
need to install anything in the \windows\system directory.
<p>
Consequently, the compiler can be run without any need for an install.
Just run the programs in \dm\bin. This is most convenient
for cases where a particular version of the compiler is needed, or to just try
it out.
<p>
Installing is as simple as going to the root directory of the hard disk and
unzipping the downloaded dm???c.zip file:
<pre>
unzip dm???c.zip
</pre>
The compiler is \dm\bin\dmc.exe. Too make it even more convenient, add
<pre>
c:\dm\bin
</pre>
to the PATH environment variable setting (c: is the drive it is installed on).
To compile a simple hello.c program:
<pre>
\dm\bin\dmc hello
</pre>
will compile and link to create hello.exe.
<p>
Notes:
<ul>
<li> To use <tt><iostream></tt> and other STL code,
download <a href="ftp://ftp.digitalmars.com/Digital_Mars_C++/STL/stlport.zip" title="download STLport 4.5.3">
STLport 4.5.3</b></a> as well. Be sure and use the switch:
<pre>
<tt>-I\dm\stlport\stlport</tt>
</pre>
so that the compiler can find <b><iostream></b>.
</li>
<li> Do not install into a subdirectory with spaces, tabs,
+ signs, commas,
or # characters in the subdirectory or path names.
</li>
</ul>
<h2>Full CD Version</h2>
Documentation is provided in HTML format, which means it is easiest
to read it in a browser, such as Netscape or Explorer.
<p>
To read the <a href="index.html">documentation</a>,
bring up the browser, and type in:
