How can I capture the current directory as an absolute pathname in a make variable?

问题

I'd like to get the current directory during a GNUmake file run put into a make variable.

What is the syntax to do this? Something like this?

DIR := $(PWD)

回答1:

Um, no, $PWD is sometimes defined in your environment and thus inherited by make, but oftentimes not. You need $CURDIR.

DIR := ${CURDIR}
