Hi all, First of all, thanks a lot for the good work on GNU Make!
I have a piece of Makefile that started behaving differently in the migration from 3.81 to 3.82, and I'm tempted to call it a bug. Using the attached Makefile (I spent quite a while to strip it down from an Automake generated file), Make 3.81 reports: $ make echo accel.dat >accel.dat echo "{accel.dat}" {accel.dat} test -n "accel.dat" echo accel.pdf >accel.eps Which is what I expect. But Make 3.82 reports: $ LC_ALL=C gmake -rR gmake: Circular accel.pdf <- accel.pdf dependency dropped. echo "{}" {} test -n "" gmake: *** [accel.pdf] Error 1 I would have understood that something be reported about accel.eps, but I don't understand what it means about accel.pdf. It would be really nice to have more details about those "circular dependencies". And see how $< is expanding to nothing. Weirdly enough, if I comment the "document.pdf" dependency, which is not involved in plain "make all", it works. If I move it, it works too. If I compare the --print-db without-document.pdf -> with-document.pdf, I can see that things about accel.pdf differ (and $< is not defined), but it does not help me understand what's wrong: accel.pdf: -# Implicit rule search has not been done. -# File does not exist. +# Implicit rule search has been done. +# Implicit/static pattern stem: `accel' +# Also makes: accel.eps +# Modification time never checked. # File has been updated. -# Successfully updated. +# Failed to be updated. +# automatic +# @ := accel.pdf +# automatic +# % := +# automatic +# * := accel +# automatic +# + := +# automatic +# | := +# automatic +# < := +# automatic +# ^ := +# automatic +# ? := +# variable set hash-table stats: +# Load=8/32=25%, Rehash=0, Collisions=1/19=5% +# recipe to execute (from `Makefile', line 9): + echo "{$<}" + test -n "$<" There might be something I did not notice, I don't know. Any help would be appreciated. Please, keep me in CC as I am not member of this list, nor reading the newsgroup.
