Package: make
Version: 4.2.1-1
Severity: normal
Given the following Makefile:
--- BEGIN ---
PATH := /nonexistent:$(PATH)
default:
@echo "make variable PATH=$(PATH)"
@echo "in target commands, PATH=$$PATH"
@echo "in \$$(shell commands), PATH=$(shell echo "$$PATH")"
--- END ---
'make' generates the output for me:
make variable
PATH=/nonexistent:/home/ben/bin:/usr/lib/ccache:/usr/local/sbin:/usr/sbin:/sbin:/home/ben/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
in target commands,
PATH=/nonexistent:/home/ben/bin:/usr/lib/ccache:/usr/local/sbin:/usr/sbin:/sbin:/home/ben/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
in $(shell commands),
PATH=/home/ben/bin:/usr/lib/ccache:/usr/local/sbin:/usr/sbin:/sbin:/home/ben/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
I can't see any documentation that says the PATH variable is special,
so I think this is a bug. I would guess that make defers evaluating
the PATH variable into the environment, in case it's recursively
expanded, but only re-evaulates it before running target commands.
