--- Begin Message ---Follow-up Comment #2, bug #58420 (project make): $(shell) commands in a recipe... well, we've all seen it done. But, hang on, PATH doesn't behave specially for me: martind@sirius:~/tmp/make-58420$ cat Makefile NOT_PATH := /nonexistent:$(NOT_PATH) $(shell echo during parsing NOT_PATH=$(NOT_PATH) 1>&2) default:; @echo "make variable NOT_PATH=$(NOT_PATH)"; echo "in target commands, NOT_PATH=$$NOT_PATH"; echo "in \$$(shell commands), NOT_PATH=$(shell echo "$$NOT_PATH")" martind@sirius:~/tmp/make-58420$ NOT_PATH=export-me make during parsing NOT_PATH=/nonexistent:export-me make variable NOT_PATH=/nonexistent:export-me in target commands, NOT_PATH=/nonexistent:export-me in $(shell commands), NOT_PATH=export-me martind@sirius:~/tmp/make-58420$ (I put the recipe on one line because tabs often don't come out in the mail.) Seeing: Component Version: 4.3 I worried that it might be due to the new spawning code, but the results above, which I think are consistent with the reporter's, were from make-4.1. I get the same from 4.0 and even 3.81. After puzzling over the code, I belatedly realized that my "during parsing" line above isn't doing the same as the $(shell) in the recipe. The former is passing the Make variable's value to $(shell), where the latter is getting it out of the environment given to $(shell). The code-comment here appears likely to pertain: http://git.savannah.gnu.org/cgit/make.git/tree/src/function.c#n1727 ... which points us at: https://savannah.gnu.org/bugs/?func=detailitem&item_id=10593 I think this is a duplicate. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?58420> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
