/STUB   (MS-DOS Stub File Name)

|  Overview |  How Do I |  Linker Options

The MS-DOS Stub File Name (/STUB:filename) option attaches an MS-DOS stub program to a Win32 program.

A stub program is invoked if the file is executed in MS-DOS. It usually displays an appropriate message; however, any valid MS-DOS application can be a stub program.

Specify a filename for the stub program after a colon (:) on the command line. The linker checks filename to be sure that it is a valid MS-DOS executable file, and issues an error message if the file is not valid. The program must be an .EXE file; a .COM file is invalid for a stub program.

If this option is not used, the linker attaches a default stub program that issues the following message:

This program cannot be run in MS-DOS mode.
