Q: I'm trying to run gcc, but all I get is a message saying
"Load error: no DPMI - Get csdpmi*.zip". What am I doing wrong?
A: 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
(v2misc/csdpmi4b.zip from SimTel.NET
mirrors) which is a free DPMI server written for DJGPP.
If you already have CWSDPMI installed, and these messages still appear,
it might be because of a messed up PATH setting. The DJGPP
startup code looks for cwsdpmi.exe along the PATH, and,
being optimized for size, it might not be robust enough to cope with
all possible cases of weirdness in the value of PATH. Try to
copy cwsdpmi.exe into the same directory as the program you are
invoking, and if that helps, change your PATH as appropriate.
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 autoexec.nt file and remove the line which loads
dosx.exe, 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.
