Hi,

I'm trying to change over from MSVC++ to dmc and I've been running into a
few problems.
The program I am trying to compile is a 3D Terrain viewing app writtin using
OpenGL and
the FLTK opengl library. After a few hours of tinkering, I was able to
create a .def file
which fixed my unresolved external woes (or at least now the compiler
doesn't complain,
who knows what will happen once I get my current problem fixed.) I used
MSVC++'s
link /lib /convert to change the lib files to the old COFF format, then used
coff2omf to convert to OMF.
To create my def file I used libunres to get the unmangled versions of
names, then used these to create the def file.
Was this correct? Anyways, my main problem now is the errors OPTLINK is
giving me which
I cannot find explanations to in the documentation. Can anyone give me any
ideas on what
flags/switches I need to use or what the hell I do to resolve this
USE16/USE32 mismatch which
I think is at the root of my problem? From what I can gather, the memory
module the compiler
is using is incorrect. Any help? plllllllease?? Thanks!

Oops, forgot to mention one thing that may help. The warning about
USE16/USE32 Mismatch and frame errors only appeared after I
made my .def file. Could it be that the compiler expects me to put
more information into the def file than I have included? I only put in
enough to fix the unresolved externals. Anyways, I thought maybe
posting the def file too might help. So here goes:

The mismatch means you are trying to link together 16 bit code and 32 bit
code. Check carefully that all the code, libraries, etc., you are linking
together are either all 16 bit code or all 32 bit code.

Hmm.. well, I've double checked all the libraries I've added and they
were all converted from 32bit MSVC++ libraries and seem to work
fine. The program is a 32 bit program. This error message seems
particularly interesting: "OPTLINK : Warning 174: 32-bit Segments
Inappropriate for 16-bit Segmented output." Does this mean OPTLINK
is trying to create 16bit output? Then I would understand why I am having
this problem as everything I'm using is 32bit. I thought however that if
a memory model isn't specified OPTLINK defaults to 32bit output??
Perhaps if I explicitly state the memory model I want in my def file?
