<h2>6.2 GCC says "No DPMI"</h2>

<p><em><strong>Q</strong>: I'm trying to run <code>gcc</code>, but all I get is a message saying
"Load error: no DPMI - Get csdpmi*.zip".  What am I doing wrong?</em>

<br><p>
<p><strong>A</strong>: You don't have a DPMI server installed, and DJGPP v2 requires it
to run.  You can either use one of the commercial DPMI servers (e.g.,
run GCC in a DOS box from Windows) or download and install CWSDPMI
(<code>v2misc/csdpmi4b.zip</code> from SimTel.NET
mirrors) which is a free DPMI server written for DJGPP.

<p>If you already have CWSDPMI installed, and these messages still appear,
it might be because of a messed up <code>PATH</code> setting.  The DJGPP
startup code looks for <code>cwsdpmi.exe</code> along the <code>PATH</code>, and,
being optimized for size, it might not be robust enough to cope with
all possible cases of weirdness in the value of <code>PATH</code>.  Try to
copy <code>cwsdpmi.exe</code> into the same directory as the program you are
invoking, and if that helps, change your <code>PATH</code> as appropriate.

<p>If you see the message "Load error: no DPMI - Get csdpmi*.zip" on
Windows/NT, it most probably means that you have disabled the DPMI
services built into NT.  One way that this might happen is if you edit
the <code>autoexec.nt</code> file and remove the line which loads
<code>dosx.exe</code>, or change some of the parameters on that line.  You
cannot use CWSDPMI on NT, so your only bet is to restore NT's built-in
DPMI services.
