72 will be read for this list of specifications.
75 can be found, it is also read (see
78 This manual page is intended as a reference document only.
79 For a more thorough introduction to
81 and makefiles, please refer to
82 .%T "Make \- A Tutorial" .
84 The options are as follows:
87 Make archive errors non-fatal, causing make just to skip the remainder
88 or all of the archive and continue after printing a message.
90 Try to be backwards compatible by executing a single shell per command and
91 by executing the commands to make the sources of a dependency line in sequence.
92 This is turned on by default unless
98 before reading the makefiles or doing anything else.
101 options are specified, each is interpreted relative to the previous one:

164 standard input is read.
165 Multiple makefiles may be specified, and are read in the order specified.
166 .It Fl I Ar directory
167 Specify a directory in which to search for makefiles and included makefiles.
168 The system makefile directory (or directories, see the
170 option) is automatically included as part of this list.

232 Multiple instances of this option may be specified;
233 the variables will be printed one per line,
234 with a blank line for each null or undefined variable.

244 Set the value of the variable
250 There are seven different types of lines in a makefile: file dependency
251 specifications, shell commands, variable assignments, include statements,
252 conditional directives, for loops, and comments.
254 In general, lines may be continued from one line to the next by ending
255 them with a backslash
257 The trailing newline character and initial whitespace on the following
258 line are compressed into a single space.
259 .Sh FILE DEPENDENCY SPECIFICATIONS
260 Dependency lines consist of one or more targets, an operator, and zero
262 This creates a relationship where the targets
265 and are usually created from them.
266 The exact relationship between the target and the source is determined
267 by the operator that separates them.
268 The three operators are as follows:
271 A target is considered out-of-date if its modification time is less than
272 those of any of its sources.
273 Sources for a target accumulate over dependency lines when this operator
275 The target is removed if
279 Targets are always re-created, but not until all sources have been
280 examined and re-created as necessary.
281 Sources for a target accumulate over dependency lines when this operator
283 The target is removed if
287 If no sources are specified, the target is always re-created.
288 Otherwise, a target is considered out-of-date if any of its sources has
289 been modified more recently than the target.
290 Sources for a target do not accumulate over dependency lines when this
292 The target will not be removed if
297 Targets and sources may contain the shell wildcard expressions
308 may only be used as part of the final
309 component of the target or source, and must be used to describe existing
313 need not necessarily be used to describe existing files.
314 Expansion is in directory order, not alphabetically as done in the shell.
316 Each target may have associated with it a series of shell commands, normally
317 used to create the target.
318 Each of the commands in this script
320 be preceded by a tab.
321 While any target may appear on a dependency line, only one of these
322 dependencies may be followed by a creation script, unless the
326 If the first characters of the command line are
331 the command is treated specially.
334 causes the command not to be echoed before it is executed.
337 causes any non-zero exit status of the command line to be ignored.
340 causes the command to be executed even if
342 is specified on the command line.
343 .Sh VARIABLE ASSIGNMENTS
346 are much like variables in the shell, and, by tradition,
347 consist of all upper-case letters.
348 The five operators that can be used to assign values to variables are as
352 Assign the value to the variable.
353 Any previous value is overridden.
355 Append the value to the current value of the variable.
357 Assign the value to the variable if it is not already defined.
359 Assign with expansion, i.e., expand the value before assigning it
361 Normally, expansion is not done until the variable is referenced.
363 Expand the value and pass it to the shell for execution and assign
364 the result to the variable.
365 Any newlines in the result are replaced with spaces.
368 Any whitespace before the assigned
370 is removed; if the value is being appended, a single space is inserted
371 between the previous contents of the variable and the appended value.
373 Variables are expanded by surrounding the variable name with either
378 and preceding it with
381 If the variable name contains only a single letter, the surrounding
382 braces or parentheses are not required.
383 This shorter form is not recommended.
385 Variable substitution occurs at two distinct times, depending on where
386 the variable is being used.
387 Variables in dependency lines are expanded as the line is read.
388 Variables in shell commands are expanded when the shell command is
391 The four different classes of variables (in order of increasing precedence)
394 .It Environment variables
395 Variables defined as part of
399 Variables defined in the makefile or in included makefiles.
400 .It Command line variables
401 Variables defined as part of the command line and variables
404 environment variable or the
408 Variables that are defined specific to a certain target.
409 The seven local variables are as follows:
410 .Bl -tag -width ".ARCHIVE"
412 The list of all sources for this target; also known as
415 The name of the archive file; also known as
418 The name/path of the source from which the target is to be transformed
421 source); also known as
424 The name of the archive member; also known as
427 The list of sources for this target that were deemed out-of-date; also
431 The file prefix of the file, containing only the file portion, no suffix
432 or preceding directory components; also known as
435 The name of the target; also known as
448 are permitted for backward
449 compatibility and are not recommended.
459 permitted for compatibility with
461 makefiles and are not recommended.
463 Four of the local variables may be used in sources on dependency lines
464 because they expand to the proper value for each target on the line.
475 sets or knows about the following internal variables or environment
477 .Bl -tag -width ".Va .MAKEFILE_LIST"
483 expands to a single dollar
489 .Pq Va argv Ns Op 0 .
491 A path to the directory where
498 to the canonical path given by
501 A path to the directory where the targets are built.
504 searches for an alternate directory to place target files.
505 It will attempt to change into this special directory
506 and will search this directory for makefiles
507 not found in the current directory.
508 The following directories are tried in order:
512 ${MAKEOBJDIRPREFIX}/`pwd`
523 The first directory that
525 successfully changes into is used.
530 is set in the environment but
532 is unable to change into the corresponding directory,
533 then the current directory is used
534 without checking the remainder of the list.
535 If they are undefined and
537 is unable to change into any of the remaining three directories,
538 then the current directory is used.
543 must be environment variables and should not be set on
551 to the canonical path given by
553 .It Va .MAKEFILE_LIST
556 reads various makefiles, including the default files and any
557 obtained from the command line and
559 directives, their names will be automatically appended to the
562 They are added right before
564 begins to parse them, so that the name of the current makefile is the
565 last word in this variable.
567 The environment variable
569 may contain anything that
573 Its contents are stored in
577 All options and variable assignments specified on
579 command line are appended to the
581 variable which is then
582 entered into the environment as
584 for all programs which
587 By modifying the contents of the
589 variable, makefile can alter the contents of the
591 environment variable made available for all programs which
593 executes; compare with the
595 special target below.
597 When passing macro definitions and flag arguments in the
599 environment variable,
600 space and tab characters are quoted by preceding them with a backslash.
603 variable from the environment,
604 all sequences of a backslash and one of space or tab
605 are replaced just with their second character
606 without causing a word break.
607 Any other occurences of a backslash are retained.
608 Groups of unquoted space, tab and newline characters cause word
611 This variable is provided for backward compatibility and
612 contains all the options from the
614 environment variable plus any options specified on
620 is currently building.
630 Name of the machine architecture
632 is running on, obtained from the
634 environment variable, or through
638 Name of the machine architecture
640 was compiled for, defined at compilation time.
642 Makefiles may assign a colon-delimited list of directories to
644 These directories will be searched for source files by
646 after it has finished parsing all input makefiles.
649 Variable expansion may be modified to select or modify each word of the
652 is whitespace-delimited sequence of characters).
653 The general format of a variable expansion is as follows:
655 .Dl {variable[:modifier[:...]]}
657 Each modifier begins with a colon and one of the following
659 The colon may be escaped with a backslash
663 .It Cm C No \&/ Ar pattern Xo
664 .No \&/ Ar replacement
668 Modify each word of the value,
669 substituting every match of the extended regular expression
677 Normally, the first occurrence of the pattern in
678 each word of the value is changed.
681 modifier causes the substitution to apply to at most one word; the
683 modifier causes the substitution to apply to as many instances of the
684 search pattern as occur in the word or words it is found in.
689 are orthogonal; the former specifies whether multiple words are
690 potentially affected, the latter whether multiple substitutions can
691 potentially occur within each affected word.
693 Replaces each word in the variable with its suffix.
695 Replaces each word in the variable with everything but the last component.
697 Converts variable to lower-case letters.
698 .It Cm M Ns Ar pattern
699 Select only those words that match the rest of the modifier.
700 The standard shell wildcard characters
707 The wildcard characters may be escaped with a backslash
709 .It Cm N Ns Ar pattern
712 but selects all words which do not match
713 the rest of the modifier.
715 Order every word in the variable alphabetically.
717 Quotes every shell meta-character in the variable, so that it can be passed
718 safely through recursive invocations of
721 Replaces each word in the variable with everything but its suffix.
723 .It Cm S No \&/ Ar old_string Xo
724 .No \&/ Ar new_string
728 Modify the first occurrence of
730 in each word of the variable's value, replacing it with
734 is appended to the last slash of the pattern, all occurrences
735 in each word are replaced.
741 is anchored at the beginning of each word.
744 ends with a dollar sign
746 it is anchored at the end of each word.
753 Any character may be used as a delimiter for the parts of the modifier
755 The anchoring, ampersand, and delimiter characters may be escaped with a
759 Variable expansion occurs in the normal fashion inside both
763 with the single exception that a backslash is used to prevent the expansion
766 not a preceding dollar sign as is usual.
767 .It Ar old_string=new_string
770 style variable substitution.
771 It must be the last modifier specified.
776 do not contain the pattern matching character
778 then it is assumed that they are
779 anchored at the end of each word, so only suffixes or entire
780 words may be replaced.
788 Replaces each word in the variable with its last component.
790 Converts variable to upper-case letters.
792 .Sh DIRECTIVES, CONDITIONALS, AND FOR LOOPS
793 Directives, conditionals, and for loops reminiscent
794 of the C programming language are provided in
796 All such structures are identified by a line beginning with a single
800 The following directives are supported:
802 .It Ic \&.include Ar <file>
803 .It Ic \&.include Ar \*qfile\*q
804 Include the specified makefile.
805 Variables between the angle brackets
806 or double quotes are expanded to form the file name.
808 are used, the included makefile is expected to be in the system
810 If double quotes are used, the including
811 makefile's directory and any directories specified using the
813 option are searched before the system
815 .It Ic .undef Ar variable
816 Un-define the specified global variable.
817 Only global variables may be un-defined.
818 .It Ic .error Ar message
819 Terminate processing of the makefile immediately.
821 makefile, the line on which the error was encountered and the specified
822 message are printed to the standard error output and
824 terminates with exit code 1.
825 Variables in the message are expanded.
826 .It Ic .warning Ar message
827 Emit a warning message.
828 The filename of the makefile,
829 the line on which the warning was encountered,
830 and the specified message are printed to the standard error output.
831 Variables in the message are expanded.
834 Conditionals are used to determine which parts of the Makefile
836 They are used similarly to the conditionals supported
837 by the C pre-processor.
838 The following conditionals are supported:
842 .Oo \&! Oc Ns Ar expression
843 .Op Ar operator expression ...
845 Test the value of an expression.
848 .Oo \&! Oc Ns Ar variable
849 .Op Ar operator variable ...
851 Test the value of a variable.
854 .Oo \&! Oc Ns Ar variable
855 .Op Ar operator variable ...
857 Test the value of a variable.
860 .Oo \&! Oc Ns Ar target
861 .Op Ar operator target ...
863 Test the target being built.
866 .Oo \&! Oc Ns Ar target
867 .Op Ar operator target ...
869 Test the target being built.
871 Reverse the sense of the last conditional.
874 .Oo \&! Oc Ns Ar expression
875 .Op Ar operator expression ...
883 .Oo \&! Oc Ns Ar variable

955 Takes a target name as an argument and evaluates to true if the target
956 was specified as part of
958 command line or was declared the default target (either implicitly or
961 before the line containing the conditional.
963 Takes a variable, with possible modifiers, and evaluates to true if
964 the expansion of the variable would result in an empty string.
966 Takes a file name as an argument and evaluates to true if the file exists.
967 The file is searched for on the system search path (see
970 Takes a target name as an argument and evaluates to true if the target
976 may also be an arithmetic or string comparison, with the left-hand side
977 being a variable expansion.
978 Variable expansion is
979 performed on both sides of the comparison, after which the integral
981 A value is interpreted as hexadecimal if it is
982 preceded by 0x, otherwise it is decimal; octal numbers are not supported.
983 The standard C relational operators are all supported.
985 variable expansion, either the left or right hand side of a
989 operator is not an integral value, then
990 string comparison is performed between the expanded

1019 If the conditional evaluates to true the parsing of the makefile continues
1021 If it evaluates to false, the following lines are skipped.
1022 In both cases this continues until a
1028 For loops are typically used to apply a set of rules to a list of files.
1029 The syntax of a for loop is:

1032 .It Ic .for Ar variable Ic in Ar expression
1039 is evaluated, it is split into words.
1043 is successively set to each word, and substituted in the
1045 inside the body of the for loop.
1047 Comments begin with a hash
1049 character, anywhere but in a shell
1050 command line, and continue to the end of the line.

1261 Specify the shell command to turn echoing on.
1263 Usually shells print the echo off command before turning echoing off.
1264 This is the exact string that will be printed by the shell and is used
1265 to filter the shell output to remove the echo off command.
1267 The shell option that turns echoing on.

1270 If error checking is on, the shell should exit if a command returns
1273 True if the shell has error control.

1321 If the last component is the same as the name of the builtin shell, no
1322 name needs to be specified; if it is different, the name must be given:

1324 \&.SHELL: path="/usr/local/bin/sh"
1327 selects the builtin shell
1329 but will execute it from

1331 Like in the previous case, it is possible to modify parameters of the builtin
1332 shell by just specifying them.

1452 in a test is very simple-minded.
1453 Currently, the only form that works is
1454 .Ql .if ${VAR} op something
1455 For instance, you should write tests as
1456 .Ql .if ${VAR} == "string"
1457 not the other way around, which would give you an error.
1459 For loops are expanded before tests, so a fragment such as:
1460 .Bd -literal -offset indent
1461 \&.for ARCH in ${SHARED_ARCHS}
1462 \&.if ${ARCH} == ${MACHINE}
1468 will not work, and should be rewritten as:
1469 .Bd -literal -offset indent
1470 \&.for ARCH in ${SHARED_ARCHS}
1471 \&.if ${MACHINE} == ${ARCH}
1477 The parsing code is broken with respect to handling a semicolon
1478 after a colon, so a fragment like this will fail:
1479 .Bd -literal -offset indent
1483 \&.for h in ${HDRS:S;^;${.CURDIR}/;}
1488 A trailing backslash in a variable value defined on the command line causes
1489 the delimiting space in the
1491 environment variable to be preceeded by that backslash.
1492 That causes a submake to not treat that space as a word delimiter.
1493 Fixing this requires a larger rewrite of the code handling command line
