+10.5 Defining and Redefining Pattern Rules
+==========================================
+
+You define an implicit rule by writing a "pattern rule".  A pattern
+rule looks like an ordinary rule, except that its target contains the
+character `%' (exactly one of them).  The target is considered a
+pattern for matching file names; the `%' can match any nonempty
+substring, while other characters match only themselves.  The
+prerequisites likewise use `%' to show how their names relate to the
+target name.
+
+   Thus, a pattern rule `%.o : %.c' says how to make any file `STEM.o'
+from another file `STEM.c'.
+
+   Note that expansion using `%' in pattern rules occurs *after* any
+variable or function expansions, which take place when the makefile is
+read.  *Note How to Use Variables: Using Variables, and *Note Functions

+
+10.5.1 Introduction to Pattern Rules
+------------------------------------
+
+A pattern rule contains the character `%' (exactly one of them) in the
+target; otherwise, it looks exactly like an ordinary rule.  The target
+is a pattern for matching file names; the `%' matches any nonempty
+substring, while other characters match only themselves.  
+
+   For example, `%.c' as a pattern matches any file name that ends in
+`.c'.  `s.%.c' as a pattern matches any file name that starts with
+`s.', ends in `.c' and is at least five characters long.  (There must
+be at least one character to match the `%'.)  The substring that the
+`%' matches is called the "stem".
+
+   `%' in a prerequisite of a pattern rule stands for the same stem
+that was matched by the `%' in the target.  In order for the pattern
+rule to apply, its target pattern must match the file name under
+consideration and all of its prerequisites (after pattern substitution)
+must name files that exist or can be made.  These files become
+prerequisites of the target.  
+
+   Thus, a rule of the form
+
+     %.o : %.c ; COMMAND...
+
+specifies how to make a file `N.o', with another file `N.c' as its
+prerequisite, provided that `N.c' exists or can be made.
+
+   There may also be prerequisites that do not use `%'; such a
+prerequisite attaches to every file made by this pattern rule.  These
+unvarying prerequisites are useful occasionally.
+
+   A pattern rule need not have any prerequisites that contain `%', or
+in fact any prerequisites at all.  Such a rule is effectively a general
+wildcard.  It provides a way to make any file that matches the target
+pattern.  *Note Last Resort::.
+
+   Pattern rules may have more than one target.  Unlike normal rules,
+this does not act as many different rules with the same prerequisites
+and commands.  If a pattern rule has multiple targets, `make' knows that
+the rule's commands are responsible for making all of the targets.  The
+commands are executed only once to make all the targets.  When searching
+for a pattern rule to match a target, the target patterns of a rule
+other than the one that matches the target in need of a rule are
+incidental: `make' worries only about giving commands and prerequisites
+to the file presently in question.  However, when this file's commands
+are run, the other targets are marked as having been updated themselves.  
+
+   The order in which pattern rules appear in the makefile is important
+since this is the order in which they are considered.  Of equally
+applicable rules, only the first one found is used.  The rules you
+write take precedence over those that are built in.  Note however, that
+a rule whose prerequisites actually exist or are mentioned always takes
+priority over a rule with prerequisites that must be made by chaining
+other implicit rules.  
+
+
+File: make.info,  Node: Pattern Examples,  Next: Automatic Variables,  Prev: Pattern Intro,  Up: Pattern Rules
+
+10.5.2 Pattern Rule Examples
+----------------------------
+
+Here are some examples of pattern rules actually predefined in `make'.
+First, the rule that compiles `.c' files into `.o' files:
+
+     %.o : %.c
+             $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
+
+defines a rule that can make any file `X.o' from `X.c'.  The command
+uses the automatic variables `$@' and `$<' to substitute the names of
+the target file and the source file in each case where the rule applies
+(*note Automatic Variables::).
+
+   Here is a second built-in rule:
+
+     % :: RCS/%,v
+             $(CO) $(COFLAGS) $<
+
+defines a rule that can make any file `X' whatsoever from a
+corresponding file `X,v' in the subdirectory `RCS'.  Since the target
+is `%', this rule will apply to any file whatever, provided the
+appropriate prerequisite file exists.  The double colon makes the rule
+"terminal", which means that its prerequisite may not be an intermediate
+file (*note Match-Anything Pattern Rules: Match-Anything Rules.).
+
+   This pattern rule has two targets:
+
+     %.tab.c %.tab.h: %.y
+             bison -d $<
+
+This tells `make' that the command `bison -d X.y' will make both
+`X.tab.c' and `X.tab.h'.  If the file `foo' depends on the files
+`parse.tab.o' and `scan.o' and the file `scan.o' depends on the file
+`parse.tab.h', when `parse.y' is changed, the command `bison -d parse.y'
+will be executed only once, and the prerequisites of both `parse.tab.o'
+and `scan.o' will be satisfied.  (Presumably the file `parse.tab.o'
+will be recompiled from `parse.tab.c' and the file `scan.o' from
+`scan.c', while `foo' is linked from `parse.tab.o', `scan.o', and its
+other prerequisites, and it will execute happily ever after.)
+
+
+File: make.info,  Node: Automatic Variables,  Next: Pattern Match,  Prev: Pattern Examples,  Up: Pattern Rules
+
+10.5.3 Automatic Variables
+--------------------------
+
+Suppose you are writing a pattern rule to compile a `.c' file into a
+`.o' file: how do you write the `cc' command so that it operates on the
+right source file name?  You cannot write the name in the command,
+because the name is different each time the implicit rule is applied.
+
+   What you do is use a special feature of `make', the "automatic
+variables".  These variables have values computed afresh for each rule
+that is executed, based on the target and prerequisites of the rule.
+In this example, you would use `$@' for the object file name and `$<'
+for the source file name.
+
+   It's very important that you recognize the limited scope in which
+automatic variable values are available: they only have values within
+the command script.  In particular, you cannot use them anywhere within
+the target list of a rule; they have no value there and will expand to
+the empty string.  Also, they cannot be accessed directly within the
+prerequisite list of a rule.  A common mistake is attempting to use
+`$@' within the prerequisites list; this will not work.  However, there
+is a special feature of GNU `make', secondary expansion (*note
+Secondary Expansion::), which will allow automatic variable values to
+be used in prerequisite lists.
+
+   Here is a table of automatic variables:
+
+`$@'
+     The file name of the target of the rule.  If the target is an
+     archive member, then `$@' is the name of the archive file.  In a
+     pattern rule that has multiple targets (*note Introduction to
+     Pattern Rules: Pattern Intro.), `$@' is the name of whichever
+     target caused the rule's commands to be run.
+
+`$%'
+     The target member name, when the target is an archive member.
+     *Note Archives::.  For example, if the target is `foo.a(bar.o)'
+     then `$%' is `bar.o' and `$@' is `foo.a'.  `$%' is empty when the
+     target is not an archive member.
+
+`$<'
+     The name of the first prerequisite.  If the target got its
+     commands from an implicit rule, this will be the first
+     prerequisite added by the implicit rule (*note Implicit Rules::).
+
+`$?'
+     The names of all the prerequisites that are newer than the target,
+     with spaces between them.  For prerequisites which are archive
+     members, only the member named is used (*note Archives::).  
+
+`$^'
+     The names of all the prerequisites, with spaces between them.  For
+     prerequisites which are archive members, only the member named is
+     used (*note Archives::).  A target has only one prerequisite on
+     each other file it depends on, no matter how many times each file
+     is listed as a prerequisite.  So if you list a prerequisite more
+     than once for a target, the value of `$^' contains just one copy
+     of the name.  This list does *not* contain any of the order-only
+     prerequisites; for those see the `$|' variable, below.  
+
+`$+'
+     This is like `$^', but prerequisites listed more than once are
+     duplicated in the order they were listed in the makefile.  This is
+     primarily useful for use in linking commands where it is
+     meaningful to repeat library file names in a particular order.
+
+`$|'
+     The names of all the order-only prerequisites, with spaces between
+     them.
+
+`$*'
+     The stem with which an implicit rule matches (*note How Patterns
+     Match: Pattern Match.).  If the target is `dir/a.foo.b' and the
+     target pattern is `a.%.b' then the stem is `dir/foo'.  The stem is
+     useful for constructing names of related files.  
+
+     In a static pattern rule, the stem is part of the file name that
+     matched the `%' in the target pattern.
+
+     In an explicit rule, there is no stem; so `$*' cannot be determined
+     in that way.  Instead, if the target name ends with a recognized
+     suffix (*note Old-Fashioned Suffix Rules: Suffix Rules.), `$*' is
+     set to the target name minus the suffix.  For example, if the
+     target name is `foo.c', then `$*' is set to `foo', since `.c' is a
+     suffix.  GNU `make' does this bizarre thing only for compatibility
+     with other implementations of `make'.  You should generally avoid
+     using `$*' except in implicit rules or static pattern rules.
+
+     If the target name in an explicit rule does not end with a
+     recognized suffix, `$*' is set to the empty string for that rule.
+
+   `$?' is useful even in explicit rules when you wish to operate on
+only the prerequisites that have changed.  For example, suppose that an
+archive named `lib' is supposed to contain copies of several object
+files.  This rule copies just the changed object files into the archive:
+
+     lib: foo.o bar.o lose.o win.o
+             ar r lib $?
+
+   Of the variables listed above, four have values that are single file
+names, and three have values that are lists of file names.  These seven
+have variants that get just the file's directory name or just the file
+name within the directory.  The variant variables' names are formed by
+appending `D' or `F', respectively.  These variants are semi-obsolete
+in GNU `make' since the functions `dir' and `notdir' can be used to get
+a similar effect (*note Functions for File Names: File Name
+Functions.).  Note, however, that the `D' variants all omit the
+trailing slash which always appears in the output of the `dir'
+function.  Here is a table of the variants:
+
+`$(@D)'
+     The directory part of the file name of the target, with the
+     trailing slash removed.  If the value of `$@' is `dir/foo.o' then
+     `$(@D)' is `dir'.  This value is `.' if `$@' does not contain a
+     slash.
+
+`$(@F)'
+     The file-within-directory part of the file name of the target.  If
+     the value of `$@' is `dir/foo.o' then `$(@F)' is `foo.o'.  `$(@F)'
+     is equivalent to `$(notdir $@)'.
+
+`$(*D)'
+`$(*F)'
+     The directory part and the file-within-directory part of the stem;
+     `dir' and `foo' in this example.
+
+`$(%D)'
+`$(%F)'
+     The directory part and the file-within-directory part of the target
+     archive member name.  This makes sense only for archive member
+     targets of the form `ARCHIVE(MEMBER)' and is useful only when
+     MEMBER may contain a directory name.  (*Note Archive Members as
+     Targets: Archive Members.)
+
+`$(<D)'
+`$(<F)'
+     The directory part and the file-within-directory part of the first
+     prerequisite.
+
+`$(^D)'
+`$(^F)'
+     Lists of the directory parts and the file-within-directory parts
+     of all prerequisites.
+
+`$(+D)'
+`$(+F)'
+     Lists of the directory parts and the file-within-directory parts
+     of all prerequisites, including multiple instances of duplicated
+     prerequisites.
+
+`$(?D)'
+`$(?F)'
+     Lists of the directory parts and the file-within-directory parts of
+     all prerequisites that are newer than the target.
+
+   Note that we use a special stylistic convention when we talk about
+these automatic variables; we write "the value of `$<'", rather than
+"the variable `<'" as we would write for ordinary variables such as
+`objects' and `CFLAGS'.  We think this convention looks more natural in
+this special case.  Please do not assume it has a deep significance;
+`$<' refers to the variable named `<' just as `$(CFLAGS)' refers to the
+variable named `CFLAGS'.  You could just as well use `$(<)' in place of
+`$<'.

+
+10.5.4 How Patterns Match
+-------------------------
+
+A target pattern is composed of a `%' between a prefix and a suffix,
+either or both of which may be empty.  The pattern matches a file name
+only if the file name starts with the prefix and ends with the suffix,
+without overlap.  The text between the prefix and the suffix is called
+the "stem".  Thus, when the pattern `%.o' matches the file name
+`test.o', the stem is `test'.  The pattern rule prerequisites are
+turned into actual file names by substituting the stem for the character
+`%'.  Thus, if in the same example one of the prerequisites is written
+as `%.c', it expands to `test.c'.
+
+   When the target pattern does not contain a slash (and it usually does
+not), directory names in the file names are removed from the file name
+before it is compared with the target prefix and suffix.  After the
+comparison of the file name to the target pattern, the directory names,
+along with the slash that ends them, are added on to the prerequisite
+file names generated from the pattern rule's prerequisite patterns and
+the file name.  The directories are ignored only for the purpose of
+finding an implicit rule to use, not in the application of that rule.
+Thus, `e%t' matches the file name `src/eat', with `src/a' as the stem.
+When prerequisites are turned into file names, the directories from the
+stem are added at the front, while the rest of the stem is substituted
+for the `%'.  The stem `src/a' with a prerequisite pattern `c%r' gives
+the file name `src/car'.
+
+
+File: make.info,  Node: Match-Anything Rules,  Next: Canceling Rules,  Prev: Pattern Match,  Up: Pattern Rules
+
+10.5.5 Match-Anything Pattern Rules
+-----------------------------------
+
+When a pattern rule's target is just `%', it matches any file name
+whatever.  We call these rules "match-anything" rules.  They are very
+useful, but it can take a lot of time for `make' to think about them,
+because it must consider every such rule for each file name listed
+either as a target or as a prerequisite.
+
+   Suppose the makefile mentions `foo.c'.  For this target, `make'
+would have to consider making it by linking an object file `foo.c.o',
+or by C compilation-and-linking in one step from `foo.c.c', or by
+Pascal compilation-and-linking from `foo.c.p', and many other
+possibilities.
+
+   We know these possibilities are ridiculous since `foo.c' is a C
+source file, not an executable.  If `make' did consider these
+possibilities, it would ultimately reject them, because files such as
+`foo.c.o' and `foo.c.p' would not exist.  But these possibilities are so
+numerous that `make' would run very slowly if it had to consider them.
+
+   To gain speed, we have put various constraints on the way `make'
+considers match-anything rules.  There are two different constraints
+that can be applied, and each time you define a match-anything rule you
+must choose one or the other for that rule.
+
+   One choice is to mark the match-anything rule as "terminal" by
+defining it with a double colon.  When a rule is terminal, it does not
+apply unless its prerequisites actually exist.  Prerequisites that
+could be made with other implicit rules are not good enough.  In other
+words, no further chaining is allowed beyond a terminal rule.
+
+   For example, the built-in implicit rules for extracting sources from
+RCS and SCCS files are terminal; as a result, if the file `foo.c,v' does
+not exist, `make' will not even consider trying to make it as an
+intermediate file from `foo.c,v.o' or from `RCS/SCCS/s.foo.c,v'.  RCS
+and SCCS files are generally ultimate source files, which should not be
+remade from any other files; therefore, `make' can save time by not
+looking for ways to remake them.
+
+   If you do not mark the match-anything rule as terminal, then it is
+nonterminal.  A nonterminal match-anything rule cannot apply to a file
+name that indicates a specific type of data.  A file name indicates a
+specific type of data if some non-match-anything implicit rule target
+matches it.
+
+   For example, the file name `foo.c' matches the target for the pattern
+rule `%.c : %.y' (the rule to run Yacc).  Regardless of whether this
+rule is actually applicable (which happens only if there is a file
+`foo.y'), the fact that its target matches is enough to prevent
+consideration of any nonterminal match-anything rules for the file
+`foo.c'.  Thus, `make' will not even consider trying to make `foo.c' as
+an executable file from `foo.c.o', `foo.c.c', `foo.c.p', etc.
+
+   The motivation for this constraint is that nonterminal match-anything
+rules are used for making files containing specific types of data (such
+as executable files) and a file name with a recognized suffix indicates
+some other specific type of data (such as a C source file).
+
+   Special built-in dummy pattern rules are provided solely to recognize
+certain file names so that nonterminal match-anything rules will not be
+considered.  These dummy rules have no prerequisites and no commands,
+and they are ignored for all other purposes.  For example, the built-in
+implicit rule
+
+     %.p :
+
+exists to make sure that Pascal source files such as `foo.p' match a
+specific target pattern and thereby prevent time from being wasted
+looking for `foo.p.o' or `foo.p.c'.
+
+   Dummy pattern rules such as the one for `%.p' are made for every
+suffix listed as valid for use in suffix rules (*note Old-Fashioned
+Suffix Rules: Suffix Rules.).

+
+10.5.6 Canceling Implicit Rules
+-------------------------------
+
+You can override a built-in implicit rule (or one you have defined
+yourself) by defining a new pattern rule with the same target and
+prerequisites, but different commands.  When the new rule is defined,
+the built-in one is replaced.  The new rule's position in the sequence
+of implicit rules is determined by where you write the new rule.
+
+   You can cancel a built-in implicit rule by defining a pattern rule
+with the same target and prerequisites, but no commands.  For example,
+the following would cancel the rule that runs the assembler:
+
+     %.o : %.s
+
+
+File: make.info,  Node: Last Resort,  Next: Suffix Rules,  Prev: Pattern Rules,  Up: Implicit Rules
+
+10.6 Defining Last-Resort Default Rules
+=======================================
+
+You can define a last-resort implicit rule by writing a terminal
+match-anything pattern rule with no prerequisites (*note Match-Anything
+Rules::).  This is just like any other pattern rule; the only thing
+special about it is that it will match any target.  So such a rule's
+commands are used for all targets and prerequisites that have no
+commands of their own and for which no other implicit rule applies.
+
+   For example, when testing a makefile, you might not care if the
+source files contain real data, only that they exist.  Then you might
+do this:
+
+     %::
+             touch $@
+
+to cause all the source files needed (as prerequisites) to be created
+automatically.
+
+   You can instead define commands to be used for targets for which
+there are no rules at all, even ones which don't specify commands.  You
+do this by writing a rule for the target `.DEFAULT'.  Such a rule's
+commands are used for all prerequisites which do not appear as targets
+in any explicit rule, and for which no implicit rule applies.
+Naturally, there is no `.DEFAULT' rule unless you write one.
+
+   If you use `.DEFAULT' with no commands or prerequisites:
+
+     .DEFAULT:
+
+the commands previously stored for `.DEFAULT' are cleared.  Then `make'
+acts as if you had never defined `.DEFAULT' at all.
+
+   If you do not want a target to get the commands from a match-anything
+pattern rule or `.DEFAULT', but you also do not want any commands to be
+run for the target, you can give it empty commands (*note Defining
+Empty Commands: Empty Commands.).
+
+   You can use a last-resort rule to override part of another makefile.

+
+10.7 Old-Fashioned Suffix Rules
+===============================
+
+"Suffix rules" are the old-fashioned way of defining implicit rules for
+`make'.  Suffix rules are obsolete because pattern rules are more
+general and clearer.  They are supported in GNU `make' for
+compatibility with old makefiles.  They come in two kinds:
+"double-suffix" and "single-suffix".
+
+   A double-suffix rule is defined by a pair of suffixes: the target
+suffix and the source suffix.  It matches any file whose name ends with
+the target suffix.  The corresponding implicit prerequisite is made by
+replacing the target suffix with the source suffix in the file name.  A
+two-suffix rule whose target and source suffixes are `.o' and `.c' is
+equivalent to the pattern rule `%.o : %.c'.
+
+   A single-suffix rule is defined by a single suffix, which is the
+source suffix.  It matches any file name, and the corresponding implicit
+prerequisite name is made by appending the source suffix.  A
+single-suffix rule whose source suffix is `.c' is equivalent to the
+pattern rule `% : %.c'.
+
+   Suffix rule definitions are recognized by comparing each rule's
+target against a defined list of known suffixes.  When `make' sees a
+rule whose target is a known suffix, this rule is considered a
+single-suffix rule.  When `make' sees a rule whose target is two known
+suffixes concatenated, this rule is taken as a double-suffix rule.
+
+   For example, `.c' and `.o' are both on the default list of known
+suffixes.  Therefore, if you define a rule whose target is `.c.o',
+`make' takes it to be a double-suffix rule with source suffix `.c' and
+target suffix `.o'.  Here is the old-fashioned way to define the rule
+for compiling a C source file:
+
+     .c.o:
+             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
+
+   Suffix rules cannot have any prerequisites of their own.  If they
+have any, they are treated as normal files with funny names, not as
+suffix rules.  Thus, the rule:
+
+     .c.o: foo.h
+             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
+
+tells how to make the file `.c.o' from the prerequisite file `foo.h',
+and is not at all like the pattern rule:
+
+     %.o: %.c foo.h
+             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
+
+which tells how to make `.o' files from `.c' files, and makes all `.o'
+files using this pattern rule also depend on `foo.h'.
+
+   Suffix rules with no commands are also meaningless.  They do not
+remove previous rules as do pattern rules with no commands (*note
+Canceling Implicit Rules: Canceling Rules.).  They simply enter the
+suffix or pair of suffixes concatenated as a target in the data base.
+
+   The known suffixes are simply the names of the prerequisites of the
+special target `.SUFFIXES'.  You can add your own suffixes by writing a
+rule for `.SUFFIXES' that adds more prerequisites, as in:
+
+     .SUFFIXES: .hack .win
+
+which adds `.hack' and `.win' to the end of the list of suffixes.
+
+   If you wish to eliminate the default known suffixes instead of just
+adding to them, write a rule for `.SUFFIXES' with no prerequisites.  By
+special dispensation, this eliminates all existing prerequisites of
+`.SUFFIXES'.  You can then write another rule to add the suffixes you
+want.  For example,
+
+     .SUFFIXES:            # Delete the default suffixes
+     .SUFFIXES: .c .o .h   # Define our suffix list
+
+   The `-r' or `--no-builtin-rules' flag causes the default list of
+suffixes to be empty.
+
+   The variable `SUFFIXES' is defined to the default list of suffixes
+before `make' reads any makefiles.  You can change the list of suffixes
+with a rule for the special target `.SUFFIXES', but that does not alter
+this variable.
