gnu make - In Makefile, how to cleanup lockfile files? -


in gnu make 3.81, need remove lockfile in event of error in part of toolchain. there special target allow me this? need write wrapper script?

in example below, need unlock_id happen if rule file.out fails.

thanks! -jeff

all: lock_id file.out unlock_id  file.out: file.in     file-maker < file.in > $@  lock_id:     lockfile file.lock  unlock_id:     rm -rf file.lock

i lock/unlock in same target file-maker:

file.out: file.in         lockfile $@.lock         file-maker < $< > $@; \         status=$$?; \         rm -f $@.lock; \         exit $$status

this executes file-maker , unlock steps in same shell, saving status of file-maker make fail if file-maker fails.
