I accidentally typed 'make' in the srcdir of a VPATH build, and was surprised to see this: $ make /bin/sh: s/^[ +-]//;s/ .*//: No such file or directory INFO: gnulib update required; running ./autogen.sh first make: -n: Command not found ./autogen.sh I am going to run ./configure with no arguments - if you wish to pass any to it, please specify them on the ./autogen.sh command line. running bootstrap... ./bootstrap: Bootstrapping from checked-out libvirt sources... ./bootstrap: getting gnulib files... Oops - we're trying to execute some fairly bogus command names, and then trying to configure in-tree (which breaks all existing VPATH builds, since automake refuses to do a VPATH build if it detects an in-tree configure). The third line (executing "-n") is fixed by updating to the latest gnulib; the rest of the problem is fixed by copying the same filtering in our cfg.mk as what gnulib just added, so that we avoid any $(shell) invocations which in turn depend on variables that are only populated by a working Makefile. With that in place, we are back to the much nicer: $ make There seems to be no Makefile in this directory. You must run ./configure before running 'make'. make: *** [abort-due-to-no-makefile] Error 1 Additionally, although harder to see - there was a trailing space in the message warning us that autogen would run an in-tree configure. * .gnulib: Update to latest, in part for maint.mk improvements. * cfg.mk (_update_required): Don't check for update in unconfigured directory. * autogen.sh (no_git): Drop trailing space.
