2987 # at make time; they should therefore not lie in the source
2988 # directory. One plan was to support this using
2989 # nodist_info_TEXINFOS or something similar. (Doing this
2990 # requires some sanity checks. For instance Automake should
2992 # dist_info_TEXINFO = foo.texi
2993 # nodist_foo_TEXINFO = included.texi
2994 # because a distributed file should never depend on a
2995 # non-distributed file.)
2997 # * If .texi files are not distributed, then .info files should
2998 # not be distributed either. There are also cases where one
2999 # want to distribute .texi files, but do not want to
3000 # distribute the .info files. For instance the Texinfo package
3001 # distributes the tool used to build these files; it would
3002 # be a waste of space to distribute them. It's not clear
3003 # which syntax we should use to indicate that .info files should
3004 # not be distributed. Akim Demaille suggested that eventually
3005 # we switch to a new syntax:
3006 # | Maybe we should take some inspiration from what's already
3007 # | done in the rest of Automake. Maybe there is too much
3008 # | syntactic sugar here, and you want
3009 # | nodist_INFO = bar.info
3010 # | dist_bar_info_SOURCES = bar.texi
3011 # | bar_texi_DEPENDENCIES = foo.texi
3012 # | with a bit of magic to have bar.info represent the whole
3013 # | bar*info set. That's a lot more verbose that the current
3014 # | situation, but it is # not new, hence the user has less
3017 # | But there is still too much room for meaningless specs:
3018 # | nodist_INFO = bar.info
3019 # | dist_bar_info_SOURCES = bar.texi
3020 # | dist_PS = bar.ps something-written-by-hand.ps
3021 # | nodist_bar_ps_SOURCES = bar.texi
3022 # | bar_texi_DEPENDENCIES = foo.texi
3023 # | here bar.texi is dist_ in line 2, and nodist_ in 4.
3025 # Back to the point, it should be clear that in order to support
3026 # non-distributed .info files, we need to build them in the
3027 # build tree, not in the source tree (non-distributed .texi
3028 # files are less of a problem, because we do not output build
3029 # rules for them). In Automake 1.7 .info build rules have been
3030 # largely cleaned up so that .info files get always build in the
3031 # build tree, even when distributed. The idea was that
3032 # (1) if during a VPATH build the .info file was found to be
3033 # absent or out-of-date (in the source tree or in the
3034 # build tree), Make would rebuild it in the build tree.
3035 # If an up-to-date source-tree of the .info file existed,
3036 # make would not rebuild it in the build tree.
3037 # (2) having two copies of .info files, one in the source tree
3038 # and one (newer) in the build tree is not a problem
3039 # because `make dist' always pick files in the build tree
3041 # However it turned out the be a bad idea for several reasons:
3042 # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
3043 # like GNU Make on point (1) above. These implementations
3044 # of Make would always rebuild .info files in the build
3045 # tree, even if such files were up to date in the source
3046 # tree. Consequently, it was impossible to perform a VPATH
3047 # build of a package containing Texinfo files using these
3048 # Make implementations.
3049 # (Refer to the Autoconf Manual, section "Limitation of
3050 # Make", paragraph "VPATH", item "target lookup", for
3051 # an account of the differences between these
3053 # * The GNU Coding Standards require these files to be built
3054 # in the source-tree (when they are distributed, that is).
3055 # * Keeping a fresher copy of distributed files in the
3056 # build tree can be annoying during development because
3057 # - if the files is kept under CVS, you really want it
3058 # to be updated in the source tree
3059 # - it is confusing that `make distclean' does not erase
3060 # all files in the build tree.
3062 # Consequently, starting with Automake 1.8, .info files are
3063 # built in the source tree again. Because we still plan to
3064 # support non-distributed .info files at some point, we
3065 # have a single variable ($INSRC) that controls whether
3066 # the current .info file must be built in the source tree
3067 # or in the build tree. Actually this variable is switched
3068 # off for .info files that appear to be cleaned; this is
3069 # for backward compatibility with package such as Texinfo,
3070 # which do things like
3071 # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
