Walter, this is my situation.

I have some old programs which compiled with the DJGPP DOS compiler.
All worked fine until my HD crashed.  I could not get the
compiler to run when I reinstalled and couldn't get it sorted out
(screen blanked out everytime I ran a program).

DigitalMars runs fine it seems.

My question:

I want to compile/build my old programs and also want to modify them so debugging is essential.

I have large amounts of data to be dynamically allocated into memory 10mbytes files, so think I need 32bit compilation?

I have 250MB of Ram to use

I dont need MFC/GUI interfaces, default screen will be fine.

Im running Windows ME.

Under what 'target' do I need to compile my programs.

(I have compiled a few of my old programs, using DOS as
the target platform, seems to run fine.  However if I
change to Wins32 I get the following error on the build:-
symbol undefined _WinMain@16)

If you can point me in the right direction, I would be
very grateful.

Kind regards

Paul W








Now ive looked through the lessons, (some) and im a bit confused as to what platform to compile my programs for.  I need to use the Debugger, as I will want to modify my existing programs.

    I cannot understand your problem with DJGPP, I have it, and works fine.

    I recomend you targeting a Win32 console application, since if you need
to manage great memory quantities they would run faster than in a DOS32
enviroment.

    Anyway, you should remember that DJGPP and DMC are not 100% compatible,
so try some compatibility tests before doing the migration.

Sounds like you want to create a win32 console program, which is the default memory model.
