Using the MKS Make Utility
Runtime Macros
MKS Make expands runtime macros when it carries out the recipes
that contain them. Except for dynamic prerequisite macros, runtime
macros do not produce useful values if placed outside recipes. The
following table describes the expansions for the runtime macros.
Macro Description
$@ The full name of the target, when building a normal target.
When building a library, it expands to the name of the archive
library (for example, if you specify the target as
mylib(member), $@ expands to mylib).
$% Also the full name of the target, when building a normal target.
When building a library, it expands to the name of the archive
member. With a target of mylib(member), $% expands to
member.
$* The target name, with no suffix. This macro produces the same
value as $(%:db).
$> The name of the library, if the current target is a library member.
With a target of mylib(member), $> produces the string
mylib.
$^ The list of prerequisites given in the current rule (that is, the rule
associated with the recipe that MKS Make is executing).
$& The list of all prerequisites in all rules that apply to the current
target. In :: rules, $& produces the same strings as $^.
$? The list of all prerequisites in all rules associated with the
current target, which are newer than that target or which need
to be created. However, in double colon rules (rules with the ::
rule operator) this macro produces the same string as the $<
macro.
$< Similar to $?, except it produces only those prerequisites that
prompt the execution of the current rule (not all changed
prerequisites associated with a single target). In normal rules,
the expansions contains the list of all changed prerequisites in
the current rule. In inference rules, however, it always contains
the single prerequisite of the executing rule. In rules using the
:! operator, this macro produces the current changed
prerequisite. For more information on rule operators, see the
man page for the make command.
$$ Produces a single dollar sign ($).
