How to get the invoking target of the GNU make Makefile?
for example, I invoke make with the following command line:
make a-target
How can I get the invoking target "a-target" in the Makefile and assign it to a variable?
Further more, if more than one target is specified on the command line:
make target1 target2 ...
How do I get all of them?
回答1:
The variable MAKECMDGOALS contains the list of targets that were specified on the command line, no matter how many (it's empty if there were none).
回答2:
Maybe you need $@?
See http://www.gnu.org/software/make/manual/make.html#Automatic-Variables for more details.
