FIX: Phar Lap err 58 Running MASM From Read-Only Drive (99575)
The information in this article applies to:
- Microsoft Macro Assembler (MASM) 6.1
This article was previously published under Q99575 SYMPTOMS
An attempt to run the Microsoft Macro Assembler (MASM) version 6.1
fails and MASM generates the following message:
Phar Lap err 58: Can't create VM swap file of size 0 in directory
This error does not occur when MASM runs in an MS-DOS window in
Microsoft Windows.
CAUSE
MASM is installed on a read-only drive, possibly a network drive. The
error occurs because the DOSXNT DOS extender attempts to create a
virtual memory swap file on the drive DOSXNT runs from when the
operating system does not support virtual memory.
RESOLUTION
To work around this problem, you can run DOSXNT on a read/write drive
listed in your PATH MS-DOS environment variable. In addition, you can
specify one of the following two environment variable settings to
prevent DOSXNT from attempting to create a swap file on the read-only
network drive:
- Set the DOSX environment variable to prevent DOSXNT from using
any virtual memory. Edit your AUTOEXEC.BAT file to include the
following:
- Set the DOSX environment variable to specify where DOSXNT
creates the virtual memory swap file. Edit your AUTOEXEC.BAT
file to include the following:
where <path> specifies the drive and directory on which to
create the temporary swap file.
STATUS
Microsoft has confirmed this to be a problem in MASM version 6.1. This
problem was corrected in MASM version 6.1a.
