Using the UtilitiesStatic pattern rulesStatic pattern rules are rules which specify multiple targets and construct the prerequisite names for eachtarget based on the target name.[target ...] : target-pattern : [prerequisite-patterns ...]The target specifies the targets the rules applies to. The target-pattern and prerequisite-patterns specifyhow to compute the prerequisites of each target. Each target is matched against the target-pattern toextract a part of the target name, called the stem. This stem is substituted into each of theprerequisite-patterns to make the prerequisite names (one from each prerequisite-pattern).Each pattern normally contains the character '%' just once. When the target-pattern matches a target,the '%' can match any part of the target name; this part is called the stem. The rest of the pattern mustmatch exactly. For example, the target foo.obj matches the pattern '%.obj', with 'foo' as the stem.The targets foo.c and foo.abs do not match that pattern.The prerequisite names for each target are made by substituting the stem for the '%' in each prerequisitepattern.Example:objects = test.obj filter.objall: $(objects)$(objects): %.obj: %.cccarm -c $< -o $@echo the stem is $*Here '$
