<h2>22.28 CGI programs and DJGPP</h2>

<p><em><strong>Q</strong>: I wrote a CGI program and compiled it with DJGPP, but it doesn't
seem to work<small>...</small>.</em>

<br><p>
<p><strong>A</strong>:  If you are using a Windows Web server, it probably won't work. 
The reason is that Windows programs cannot easily redirect standard
input and output of DOS programs (because DOS programs are run by
Windows in a different <dfn>Virtual Machine</dfn>), and many Windows Web
servers don't consider the case of a DOS CGI program, and don't bother
to include the machinery necessary to do the redirection in a way that
would work for DOS programs.  So the output of your program never gets
to the server.

<p>Consult the docs of the server: it might include some feature that
enables redirection from DOS programs.  If that doesn't help, rebuild
your CGI program with a Windows compiler, such as Mingw32 or Lcc-Win32
(see <a href="faq3_6.html">free Win32 compilers</a>), and it will work.
