I am trying to get Clipper to compile small xBase programs in a "dbDOS Pro5 (DosBox)" virtual environment on my Windows 10 computer. The hardware and software is as follows: CPU: AMD E1-6015 APU, 64-bit, 1.4 GHz / Graphics: Radeon R2 / RAM: 4 GB (3.75 GB usable) / Clipper version: 5.2d.

Clipper starts the compilation process, then stops. The message received is "dbDOS(tm)Pro - Emulator for dbase DOS has stopped working....."

It is interesting that the .EXE files from pre-compiled Clipper programs work very well under the same virtual environment, but Clipper itself does not work, so I cannot generate new compiled .exe files.

Any help would be gratefully acknowledged.

Thank you.....


Why use dbDOS Pro5 instead of DOSBox? dbDOS is mainly an (real) outdated DOSBox mod with a rather useless frontend. Most significant addition to DOSBox is dbDOS’ registration scheme. For instance, the difference with version 4(N) is the version number itself and a change in the registration scheme.

You can await something like dbDOS Pro6+ that will set you back a further $ 149,00. Whoopee, a new version, supported by dbDOS!

Just use original DOSBox.

  • Actual programming in xBase/DOS under Windows seems obsolete. Did you have a look at Harbour, harbour.github.io? That at least compiles your Clipper programs with little fuss or adjustments to genuine Windows programs. For running existing DOS programs, you could also try vDos, vdos.info. That probably would do a better job than dbDOS/DOSBox since it specializes in “serious” DOS programs. – Jos Schaars Oct 3 '16 at 6:57
  • Incidentally, your earlier suggestion for using the original DOSBox has worked out very well. I've got my Clipper systems up and running. Thanks, again. I have not looked at Harbor. For now, I am content with DosBox because I am back in business (with Clipper/DOS) on my Win10 computer. At some point in time, I will have to check out the full dBASE for Win10, and migrate there..... – Kerman Oct 4 '16 at 14:09
