	Hi, someone have experience to compile with DJGPP under dosbox running under win 7 32 bit? I've a problem to load in dosbox doslfn and cwsdpmi.. P.s exist a complete image og djgpp installation with ALL libraries instead to download one by one from djgpp site? Thanks Roberto Iw2evk

DOSBox is only for games, it doesn't work well with DJGPP. (Not sure about VDosPlus, but I'm skeptical.)

Besides, Win7 "32-bit" should work fine on its own (NTVDM). No DOSLFN nor CWSDPMI needed.

All libraries would mean thousands of files, literally. I don't think that's what you want. Maybe you meant basic/common/minimal libraries? Even those are updated occasionally, so you won't be current for long.

You could also try one of these DJGPP cross-compilers (e.g. MinGW/Win32-based): andrewwutw/build-djgpp

What's wrong with your Win7? DOS/DJGPP programs generally works under NTVDM of all 32bit Windows, including Win10...

A much better question is....

What's wrong with _you_ if you had not long ago
deleted ALL versions of WinCrap from your systems ?

I think it is some kind of misunderstanding. The console programs with line output indeed work but fullscreen console DOS programs (like Norton commander) do not work more.
So DJGPP compilers work but not the rest of programming environment like Rhide (or SetEdit) editors connected to compiler.
Another issue is some kind of memory limitation dedicated for NTVDM. If I remember it correctly the 32-bit DOS programs are limited only to 32MB which may not be enough with current DJGPP releases.

He didn't mention anything about fullscreen mode. It's well known that new WDDM drivers doesn't support fullscreen mode for console but NC or RHIDE can run in window and you can set large font size.

AFAIK DPMI limit can be easily increased.
I still see not problem running DOS/DJGPP textmode apps in NTVDM, it's problem for graphics mode apps.

Do you not know of the perfect fix for such problems ?
