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?
开发者_如何学编程DIR := $(PWD)
Um, no, $PWD
is sometimes defined in your environment and thus inherited by make, but oftentimes not. You need $CURDIR
.
DIR := ${CURDIR}
If you have one makefile including another in a different directory, PWD
and CURDIR
aren't updated for the child makefile. If that second makefile needs to know where it is, the following will tell you.
$(dir $(realpath $(lastword $(MAKEFILE_LIST))))
