+.SH NAME
+make \- GNU Make utility to maintain groups of programs
+.SH SYNOPSIS
+.B make
+[\fIOPTION\fR]... [\fITARGET\fR]...
+.SH DESCRIPTION
+.LP
+The
+.I make
+utility will determine automatically which pieces of a large program need to
+be recompiled, and issue the commands to recompile them. The manual describes
+the GNU implementation of
+.BR make ,
+which was written by Richard Stallman and Roland McGrath, and is currently
+maintained by Paul Smith. Our examples show C programs, since they are very
+common, but you can use
+.B make
+with any programming language whose compiler can be run with a shell command.
+In fact,
+.B make
+is not limited to programs. You can use it to describe any task where some
+files must be updated automatically from others whenever the others change.
+.LP
+To prepare to use
+.BR make ,
+you must write a file called the
+.I makefile
+that describes the relationships among files in your program, and provides
+commands for updating each file. In a program, typically the executable file
+is updated from object files, which are in turn made by compiling source
+files.
+.LP
+Once a suitable makefile exists, each time you change some source files,
+this simple shell command:
+.sp 1
+.RS
+.B make
+.RE
+.sp 1
+suffices to perform all necessary recompilations.
+The
+.B make
+program uses the makefile description and the last-modification times of the
+files to decide which of the files need to be updated. For each of those
+files, it issues the commands recorded in the makefile.
+.LP
+.B make
+executes commands in the
+.I makefile
+to update one or more
+.IR targets ,
+where
+.I target
+is typically a program.
+If no
+.B \-f
+option is present,
+.B make
+will look for the makefiles
+.IR GNUmakefile ,
+.IR makefile ,
+and
+.IR Makefile ,
+in that order.
+.LP
+Normally you should call your makefile either
+.I makefile
+or
+.IR Makefile .
+(We recommend
+.I Makefile
+because it appears prominently near the beginning of a directory
+listing, right near other important files such as
+.IR README .)
+The first name checked,
+.IR GNUmakefile ,
+is not recommended for most makefiles. You should use this name if you have a
+makefile that is specific to GNU Make, and will not be understood by other
+versions of
+.BR make .
+If
+.I makefile
+is '\-', the standard input is read.
+.LP
+.B make
+updates a target if it depends on prerequisite files
+that have been modified since the target was last modified,
+or if the target does not exist.
+.SH OPTIONS
+.sp 1
+.TP 0.5i
+\fB\-b\fR, \fB\-m\fR
+These options are ignored for compatibility with other versions of
+.BR make .
+.TP 0.5i
+\fB\-B\fR, \fB\-\-always\-make\fR
+Unconditionally make all targets.
+.TP 0.5i
+\fB\-C\fR \fIdir\fR, \fB\-\-directory\fR=\fIdir\fR
+Change to directory
+.I dir
+before reading the makefiles or doing anything else.
+If multiple
+.B \-C
+options are specified, each is interpreted relative to the
+previous one:
+.BR "\-C " /
+.BR "\-C " etc
+is equivalent to
+.BR "\-C " /etc.
+This is typically used with recursive invocations of
+.BR make .
+.TP 0.5i
+.B \-d
+Print debugging information in addition to normal processing.
+The debugging information says which files are being considered for
+remaking, which file-times are being compared and with what results,
+which files actually need to be remade, which implicit rules are
+considered and which are applied---everything interesting about how
+.B make
+decides what to do.
+.TP 0.5i
+.BI \-\-debug "[=FLAGS]"
+Print debugging information in addition to normal processing.
+If the
+.I FLAGS
+are omitted, then the behavior is the same as if
+.B \-d
+was specified.
+.I FLAGS
+may be any or all of the following names, comma- or space-separated. Only the
+first character is significant: the rest may be omitted:
+.I all
+for all debugging output (same as using
+.BR \-d ),
+.I basic
+for basic debugging,
+.I verbose
+for more verbose basic debugging,
+.I implicit
+for showing implicit rule search operations,
+.I jobs
+for details on invocation of commands,
+.I makefile
+for debugging while remaking makefiles,
+.I print
+shows all recipes that are run even if they are silent, and
+.I why
+shows the reason
+.BR make
+decided to rebuild each target. Use
+.I none
+to disable all previous debugging flags.
+.TP 0.5i
+\fB\-e\fR, \fB\-\-environment\-overrides\fR
+Give variables taken from the environment precedence over variables
+from makefiles.
+.TP 0.5i
+\fB\-E\fR \fIstring\fR, \fB\-\-eval\fR \fIstring\fR
+Interpret \fIstring\fR using the \fBeval\fR function, before parsing any
+makefiles.
+.TP 0.5i
+\fB\-f\fR \fIfile\fR, \fB\-\-file\fR=\fIfile\fR, \fB\-\-makefile\fR=\fIFILE\fR
+Use
+.I file
+as a makefile.
+.TP 0.5i
+\fB\-i\fR, \fB\-\-ignore\-errors\fR
+Ignore all errors in commands executed to remake files.
+.TP 0.5i
+\fB\-I\fR \fIdir\fR, \fB\-\-include\-dir\fR=\fIdir\fR
+Specifies a directory
+.I dir
+to search for included makefiles.
+If several
+.B \-I
+options are used to specify several directories, the directories are
+searched in the order specified.
+Unlike the arguments to other flags of
+.BR make ,
+directories given with
+.B \-I
+flags may come directly after the flag:
+.BI \-I dir
+is allowed, as well as
+.B \-I
+.IR dir .
+This syntax is allowed for compatibility with the C
+preprocessor's
+.B \-I
+flag.
+.TP 0.5i
+\fB\-j\fR [\fIjobs\fR], \fB\-\-jobs\fR[=\fIjobs\fR]
+Specifies the number of
+.I jobs
+(commands) to run simultaneously.
+If there is more than one
+.B \-j
+option, the last one is effective.
+If the
+.B \-j
+option is given without an argument,
+.BR make
+will not limit the number of jobs that can run simultaneously.
+.TP 0.5i
+\fB\--jobserver-style=\fR\fIstyle\fR
+The style of jobserver to use. The
+.I style
+may be one of
+.BR fifo ,
+.BR pipe ,
+or
+.B sem
+(Windows only).
+.TP 0.5i
+\fB\-k\fR, \fB\-\-keep\-going\fR
+Continue as much as possible after an error.
+While the target that failed, and those that depend on it, cannot
+be remade, the other dependencies of these targets can be processed
+all the same.
+.TP 0.5i
+\fB\-l\fR [\fIload\fR], \fB\-\-load\-average\fR[=\fIload\fR]
+Specifies that no new jobs (commands) should be started if there are
+others jobs running and the load average is at least
+.I load
+(a floating-point number).
+With no argument, removes a previous load limit.
+.TP 0.5i
+\fB\-L\fR, \fB\-\-check\-symlink\-times\fR
+Use the latest mtime between symlinks and target.
+.TP 0.5i
+\fB\-n\fR, \fB\-\-just\-print\fR, \fB\-\-dry\-run\fR, \fB\-\-recon\fR
+Print the commands that would be executed, but do not execute them (except in
+certain circumstances).
+.TP 0.5i
+\fB\-o\fR \fIfile\fR, \fB\-\-old\-file\fR=\fIfile\fR, \fB\-\-assume\-old\fR=\fIfile\fR
+Do not remake the file
+.I file
+even if it is older than its dependencies, and do not remake anything
+on account of changes in
+.IR file .
+Essentially the file is treated as very old and its rules are ignored.
+.TP 0.5i
+\fB\-O\fR[\fItype\fR], \fB\-\-output\-sync\fR[=\fItype\fR]
+When running multiple jobs in parallel with \fB-j\fR, ensure the output of
+each job is collected together rather than interspersed with output from
+other jobs. If
+.I type
+is not specified or is
+.B target
+the output from the entire recipe for each target is grouped together. If
+.I type
+is
+.B line
+the output from each command line within a recipe is grouped together.
+If
+.I type
+is
+.B recurse
+output from an entire recursive make is grouped together. If
+.I type
+is
+.B none
+output synchronization is disabled.
+.TP 0.5i
+\fB\-p\fR, \fB\-\-print\-data\-base\fR
+Print the data base (rules and variable values) that results from
+reading the makefiles; then execute as usual or as otherwise
+specified.
+This also prints the version information given by the
+.B \-v
+switch (see below).
+To print the data base without trying to remake any files, use
+.IR "make \-p \-f/dev/null" .
+.TP 0.5i
+\fB\-q\fR, \fB\-\-question\fR
+``Question mode''.
+Do not run any commands, or print anything; just return an exit status
+that is zero if the specified targets are already up to date, nonzero
+otherwise.
+.TP 0.5i
+\fB\-r\fR, \fB\-\-no\-builtin\-rules\fR
+Eliminate use of the built\-in implicit rules.
+Also clear out the default list of suffixes for suffix rules.
+.TP 0.5i
+\fB\-R\fR, \fB\-\-no\-builtin\-variables\fR
+Don't define any built\-in variables.
+.TP 0.5i
+\fB\-s\fR, \fB\-\-silent\fR, \fB\-\-quiet\fR
+Silent operation; do not print the commands as they are executed.
+.TP 0.5i
+.B \-\-no\-silent
+Cancel the effect of the \fB\-s\fR option.
+.TP 0.5i
+\fB\-S\fR, \fB\-\-no\-keep\-going\fR, \fB\-\-stop\fR
+Cancel the effect of the
+.B \-k
+option.
+.TP 0.5i
+\fB\-t\fR, \fB\-\-touch\fR
+Touch files (mark them up to date without really changing them)
+instead of running their commands.
+This is used to pretend that the commands were done, in order to fool
+future invocations of
+.BR make .
+.TP 0.5i
+.B \-\-trace
+Information about the disposition of each target is printed (why the target is
+being rebuilt and what commands are run to rebuild it).
+.TP 0.5i
+\fB\-v\fR, \fB\-\-version\fR
+Print the version of the
+.B make
+program plus a copyright, a list of authors and a notice that there
+is no warranty.
+.TP 0.5i
+\fB\-w\fR, \fB\-\-print\-directory\fR
+Print a message containing the working directory
+before and after other processing.
+This may be useful for tracking down errors from complicated nests of
+recursive
+.B make
+commands.
+.TP 0.5i
+.B \-\-no\-print\-directory
+Turn off
+.BR \-w ,
+even if it was turned on implicitly.
+.TP 0.5i
+.BI \-\-shuffle "[=MODE]"
+Enable shuffling of goal and prerequisite ordering.
+.I MODE
+is one of
+.I none
+to disable shuffle mode,
+.I random
+to shuffle prerequisites in random order,
+.I reverse
+to consider prerequisites in reverse order, or an integer
+.I <seed>
+which enables
+.I random
+mode with a specific
+.I seed
+value. If
+.I MODE
+is omitted the default is
+.IR random .
+.TP 0.5i
+\fB\-W\fR \fIfile\fR, \fB\-\-what\-if\fR=\fIfile\fR, \fB\-\-new\-file\fR=\fIfile\fR, \fB\-\-assume\-new\fR=\fIfile\fR
+Pretend that the target
+.I file
+has just been modified.
+When used with the
+.B \-n
+flag, this shows you what would happen if you were to modify that file.
+Without
+.BR \-n ,
+it is almost the same as running a
+.I touch
+command on the given file before running
+.BR make ,
+except that the modification time is changed only in the imagination of
+.BR make .
+.TP 0.5i
+.B \-\-warn\-undefined\-variables
+Warn when an undefined variable is referenced.
+.SH "EXIT STATUS"
+GNU Make exits with a status of zero if all makefiles were successfully parsed
+and no targets that were built failed. A status of one will be returned
+if the
+.B \-q
+flag was used and
+.B make
+determines that a target needs to be rebuilt. A status of two will be
+returned if any errors were encountered.
+.SH "SEE ALSO"
+The full documentation for
+.B make
+is maintained as a Texinfo manual. If the
+.B info
+and
+.B make
+programs are properly installed at your site, the command
+.IP
+.B info make
+.PP
+should give you access to the complete manual.
