The One Line You Should Add to Every Makefile

John Graham-Cumming, who’s just written the GNU Make Book (Amazon):


print-%: ; @echo $*=$($*)

It allows you to quickly get the value of any makefile variable. For example, suppose you want to know the value of a variable called SOURCE_FILES. You’d just type:

make print-SOURCE_FILES

This works with the 2006 version of GNU Make that comes with Xcode.

not to every makefile: only to GNU makefile. bmake has this builtin make -VSORUCE_FILES
