|

| 2780 | # files.
|
|---|
| 2781 | #
|
|---|
| 2782 | # * Non-distributed .texi files is important in some packages
|
|---|
| 2783 | # where .texi files are built at make time, probably using
|
|---|
| 2784 | # other binaries built in the package itself, maybe using
|
|---|
| 2785 | # tools or information found on the build host. Because
|
|---|
| 2786 | # these files are not distributed they are always rebuilt
|
|---|
| 2787 | # at make time; they should therefore not lie in the source
|
|---|
| 2788 | # directory. One plan was to support this using
|
|---|
| 2789 | # nodist_info_TEXINFOS or something similar. (Doing this
|
|---|
| 2790 | # requires some sanity checks. For instance Automake should
|
|---|
| 2791 | # not allow:
|
|---|
| 2792 | # dist_info_TEXINFO = foo.texi
|
|---|
| 2793 | # nodist_foo_TEXINFO = included.texi
|
|---|
| 2794 | # because a distributed file should never depend on a
|
|---|
| 2795 | # non-distributed file.)
|
|---|
| 2796 | #
|
|---|
| 2797 | # * If .texi files are not distributed, then .info files should
|
|---|
| 2798 | # not be distributed either. There are also cases where one
|
|---|
| 2799 | # want to distribute .texi files, but do not want to
|
|---|
| 2800 | # distribute the .info files. For instance the Texinfo package
|
|---|
| 2801 | # distributes the tool used to build these files; it would
|
|---|
| 2802 | # be a waste of space to distribute them. It's not clear
|
|---|
| 2803 | # which syntax we should use to indicate that .info files should
|
|---|
| 2804 | # not be distributed. Akim Demaille suggested that eventually
|
|---|
| 2805 | # we switch to a new syntax:
|
|---|
| 2806 | # | Maybe we should take some inspiration from what's already
|
|---|
| 2807 | # | done in the rest of Automake. Maybe there is too much
|
|---|
| 2808 | # | syntactic sugar here, and you want
|
|---|
| 2809 | # | nodist_INFO = bar.info
|
|---|
| 2810 | # | dist_bar_info_SOURCES = bar.texi
|
|---|
| 2811 | # | bar_texi_DEPENDENCIES = foo.texi
|
|---|
| 2812 | # | with a bit of magic to have bar.info represent the whole
|
|---|
| 2813 | # | bar*info set. That's a lot more verbose that the current
|
|---|
| 2814 | # | situation, but it is # not new, hence the user has less
|
|---|
| 2815 | # | to learn.
|
|---|
| 2816 | # |
|
|---|
| 2817 | # | But there is still too much room for meaningless specs:
|
|---|
| 2818 | # | nodist_INFO = bar.info
|
|---|
| 2819 | # | dist_bar_info_SOURCES = bar.texi
|
|---|
| 2820 | # | dist_PS = bar.ps something-written-by-hand.ps
|
|---|
| 2821 | # | nodist_bar_ps_SOURCES = bar.texi
|
|---|
| 2822 | # | bar_texi_DEPENDENCIES = foo.texi
|
|---|
| 2823 | # | here bar.texi is dist_ in line 2, and nodist_ in 4.
|
|---|
| 2824 | #
|
|---|
| 2825 | # Back to the point, it should be clear that in order to support
|
|---|
| 2826 | # non-distributed .info files, we need to build them in the
|
|---|
| 2827 | # build tree, not in the source tree (non-distributed .texi
|
|---|
| 2828 | # files are less of a problem, because we do not output build
|
|---|
| 2829 | # rules for them). In Automake 1.7 .info build rules have been
|
|---|
| 2830 | # largely cleaned up so that .info files get always build in the
|
|---|
| 2831 | # build tree, even when distributed. The idea was that
|
|---|
| 2832 | # (1) if during a VPATH build the .info file was found to be
|
|---|
| 2833 | # absent or out-of-date (in the source tree or in the
|
|---|
| 2834 | # build tree), Make would rebuild it in the build tree.
|
|---|
| 2835 | # If an up-to-date source-tree of the .info file existed,
|
|---|
| 2836 | # make would not rebuild it in the build tree.
|
|---|
| 2837 | # (2) having two copies of .info files, one in the source tree
|
|---|
| 2838 | # and one (newer) in the build tree is not a problem
|
|---|
| 2839 | # because `make dist' always pick files in the build tree
|
|---|
| 2840 | # first.
|
|---|
| 2841 | # However it turned out the be a bad idea for several reasons:
|
|---|
| 2842 | # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
|
|---|
| 2843 | # like GNU Make on point (1) above. These implementations
|
|---|
| 2844 | # of Make would always rebuild .info files in the build
|
|---|
| 2845 | # tree, even if such files were up to date in the source
|
|---|
| 2846 | # tree. Consequently, it was impossible to perform a VPATH
|
|---|
| 2847 | # build of a package containing Texinfo files using these
|
|---|
| 2848 | # Make implementations.
|
|---|
| 2849 | # (Refer to the Autoconf Manual, section "Limitation of
|
|---|
| 2850 | # Make", paragraph "VPATH", item "target lookup", for
|
|---|
| 2851 | # an account of the differences between these
|
|---|
| 2852 | # implementations.)
|
|---|
| 2853 | # * The GNU Coding Standards require these files to be built
|
|---|
| 2854 | # in the source-tree (when they are distributed, that is).
|
|---|
| 2855 | # * Keeping a fresher copy of distributed files in the
|
|---|
| 2856 | # build tree can be annoying during development because
|
|---|
| 2857 | # - if the files is kept under CVS, you really want it
|
|---|
| 2858 | # to be updated in the source tree
|
|---|
| 2859 | # - it is confusing that `make distclean' does not erase
|
|---|
| 2860 | # all files in the build tree.
|
|---|
| 2861 | #
|
|---|
| 2862 | # Consequently, starting with Automake 1.8, .info files are
|
|---|
| 2863 | # built in the source tree again. Because we still plan to
|
|---|
| 2864 | # support non-distributed .info files at some point, we
|
|---|
| 2865 | # have a single variable ($INSRC) that controls whether
|
|---|
| 2866 | # the current .info file must be built in the source tree
|
|---|
| 2867 | # or in the build tree. Actually this variable is switched
|
|---|
| 2868 | # off for .info files that appear to be cleaned; this is
|

| 2869 | # for backward compatibility with package such as Texinfo,
