Hi, I often use the dry-run option to debug makefiles. However, I've attached a makefile where make does not execute all of the commands "make -n" said it would. Below is a sequence of commands to be run with the attached makefile. The inline comments describe my expectations . I've pasted a sample output run of these commands here <http://pastebin.com/Lrht60JH>.
I am using GNU Make 3.81 built for x86_64-pc-linux-gnu Thanks, Sam #################################################### # start by building everything make # check that build is clean make # yes build is clean # what files were created? ls # let's update foo.in touch foo.in # what does make say it will do? make -n # okay, let's run make make # why didn't make do what "make -n" said it would do? try again? make # nope. what does make say it will do? make -n #################################################### #################################################### # let's clean up the list files make clean_lists # what does make say it will do? (now with debugging output) make -r -d -n # see the line that says "Must remake target `list'." # okay, let's run make with debugging output make -r -d # see that there is no line mentioning remaking target `list' # again make differs between dry and actual runs #################################################### #################################################### # let's clean up the list files make clean_lists # let's store the commands make says it would run during the dry run make -n > scratch.sh # let's run those commands sh scratch.sh # now what does make say? make # see that build would be clean if make did what it said it would do during dry-run ####################################################
