NMAKE Options 

NMAKE options are described in the following table. Options are preceded by either a slash (/) or a dash (–) and are not case sensitive. Use !CMDSWITCHES to change option settings in a makefile or in Tools.ini.

Option	Purpose
/A	Forces build of all evaluated targets, even if not out-of-date with respect to dependents. Does not force build of unrelated targets.
/B	Forces build even if timestamps are equal. Recommended only for very fast systems (resolution of two seconds or less).
/C	Suppresses default output, including nonfatal NMAKE errors or warnings, timestamps, and NMAKE copyright message. Suppresses warnings issued by /K.
/D	Displays timestamps of each evaluated target and dependent and a message when a target does not exist. Useful with /P for debugging a makefile. Use !CMDSWITCHES to set or clear /D for part of a makefile.
/E	Causes environment variables to override makefile macro definitions.
/ERRORREPORT[NONE | PROMPT | QUEUE | SEND ]	If nmake.exe fails at runtime, you can use /ERRORREPORT to send information to Microsoft about these internal errors. For more information about /ERRORREPORT, see /errorReport (Report Internal Compiler Errors).
/F filename	Specifies filename as a makefile. Spaces or tabs can precede filename. Specify /F once for each makefile. To supply a makefile from standard input, specify a dash (–) for filename, and end keyboard input with either F6 or CTRL+Z.
/G	Displays the makefiles included with the !INCLUDE directive. See Makefile Preprocessing Directives for more information.
/HELP, /?	Displays a brief summary of NMAKE command-line syntax.
/I	Ignores exit codes from all commands. To set or clear /I for part of a makefile, use !CMDSWITCHES. To ignore exit codes for part of a makefile, use a dash (–) command modifier or .IGNORE. Overrides /K if both are specified.
/K	Continues building unrelated dependencies, if a command returns an error. Also issues a warning and returns an exit code of 1. By default, NMAKE halts if any command returns a nonzero exit code. Warnings from /K are suppressed by /C; /I overrides /K if both are specified.
/N	Displays but does not execute commands; preprocessing commands are executed. Does not display commands in recursive NMAKE calls. Useful for debugging makefiles and checking timestamps. To set or clear /N for part of a makefile, use !CMDSWITCHES.
/NOLOGO	Suppresses the NMAKE copyright message.
/P	Displays information (macro definitions, inference rules, targets, .SUFFIXES list) to standard output, and then runs the build. If no makefile or command-line target exists, it displays information only. Use with /D to debug a makefile.
/Q	Checks timestamps of targets; does not run the build. Returns a zero exit code if all targets are up-to-date and a nonzero exit code if any target is not. Preprocessing commands are executed. Useful when running NMAKE from a batch file.
/R	Clears the .SUFFIXES list and ignores inference rules and macros that are defined in the Tools.ini file or that are predefined.
/S	Suppresses display of executed commands. To suppress display in part of a makefile, use the @ command modifier or .SILENT. To set or clear /S for part of a makefile, use !CMDSWITCHES.
/T	Updates timestamps of command-line targets (or first makefile target) and executes preprocessing commands but does not run the build.
/U	Must be used in conjunction with /N. Dumps inline NMAKE files so that the /N output can be used as a batch file.
/X filename	Sends NMAKE error output to filename instead of standard error. Spaces or tabs can precede filename. To send error output to standard output, specify a dash (–) for filename. Does not affect output from commands to standard error.
/Y	Disables batch-mode inference rules. When this option is selected, all batch-mode inference rules are treated as regular inference rules.
