the default rule in startup.mk:
%$O : %.c
rule1
If you use the -v option, make prints a warning when it replaces a meta-rule.
4. When transitive closure is calculated, the new meta-rules generated are added to the end of
the list of possible meta-rules. Thus, make always finds the explicit rules first, so they take
precedence over generated rules. You can use the -v option to see what rules make
generates and the order they appear in.
5. make performs two passes through the rules. On the first pass it attempts to find a match
with an explicit rule in the makefile; if this does not succeed, make performs a second pass
to find a match with an existing file.
Suffix Rules
make treats targets that begin with a period and contain no slashes or percent signs as suffix rules.
If there is only one period in the target, it is a single-suffix inference rule. Targets with two periods
are double-suffix inference rules. Suffix rules do not have prerequisites but do have commands
associated with them.
When make finds no explicit rule to update a target, it checks the suffix of that target (.s1) against
the suffix rules. make examines a prerequisite based on the base name of the target with the
second suffix (.s2) appended, and if the target is out-of-date with respect to this prerequisite, make
executes the recipe for that inference rule.
If the target to be built does not contain a suffix and there is no rule for the target, make checks the
single suffix inference rules. The single suffix inference rules define how to build a target 'br 'ne 5v
if make finds a rule with one of the single suffixes appended. A rule with one suffix .s2 defines how
to build target from target.s2.
Any suffixes used in a suffix rule must appear as a prerequisite of the special target .SUFFIXES.
The order that the suffixes appear in the .SUFFIXES rule determines the order make checks the
suffix rules in. New suffixes and suffix rules are added to the existing list. To turn off the suffix
rules, place
.SUFFIXES:
in your makefile. This clears the prerequisites of the .SUFFIXES target and prevents the enaction
of any suffix rules.
The search algorithm used for suffix rules depends on whether or not the .POSIX special target is
