currently, i have a rule that i expect to invoke with a couple variables
from the command line -- call them A and B:
$ make A=somevalue B=someothervalue target
and the makefile will have the target:
target:
@echo "A = $A"
@echo "B = $B"
... rest of rule ...
now, for efficiency, i'll always use these variables as "${A}/${B}", so i
just want to temporarily set that value to, say, C (and *only* within the
scope of this rule):
target:
@echo "A = $A"
@echo "B = $B"
C=${A}/${B}
and i can see that C is, in fact, being set to the appropriate value. but
how do i use that value of C in the rest of the commands in the rule?
i've tried variations of $C, $$C and so on. what painfully obvious
variation am i missing so that the variable C is available only for the
rest of this rule?
