PRB: Cannot Build in PWB with SHARE.EXE and OutputTo=NUL

ID: Q88508

7.00 | 7.00 MS-DOS | WINDOWS kbtool kberrmsg kbbuglist kbprb

The information in this article applies to:

Microsoft Programmer's WorkBench for MS-DOS, version 2.0

SYMPTOMS

Microsoft Programmer's WorkBench (PWB) version 2.0 supplied with Microsoft C/C++ version 7.0 may generate the following error messages when building a project:

   NUL - Permission Denied

   cannot compile

These errors will appear in PWB message boxes.

CAUSE

The following conditions will cause PWB to display the messages:

SHARE.EXE has been executed.
"OutputTo=NUL" has been added to the SYSTEM.INI file under the [Debug] section.
An application is being built in PWB.

PWB is using the NUL device that is already in use by Windows. You can see similar behavior simply by typing "ECHO > NUL" at an MS-DOS command prompt with SHARE.EXE loaded and "OutputTo=NUL" set.

RESOLUTION

To work around this problem, do one of the following:

Remove SHARE.EXE.
-or-
Remove the "OutputTo=NUL" statement and only insert this when running the Windows debug kernel. You can append a couple statements to N2D.BAT and D2N.BAT to change SYSTEM.INI files; one with the [Debug] section and one without.
-or-
Build the project outside of PWB.
