Because - # these files are not distributed they are always rebuilt - # at make time; they should therefore not lie in the source - # directory. One plan was to support this using - # nodist_info_TEXINFOS or something similar. (Doing this - # requires some sanity checks. For instance Automake should - # not allow: - # dist_info_TEXINFOS = foo.texi - # nodist_foo_TEXINFOS = included.texi - # because a distributed file should never depend on a - # non-distributed file.) - # - # * If .texi files are not distributed, then .info files should - # not be distributed either. There are also cases where one - # wants to distribute .texi files, but does not want to - # distribute the .info files. For instance the Texinfo package - # distributes the tool used to build these files; it would - # be a waste of space to distribute them. It's not clear - # which syntax we should use to indicate that .info files should - # not be distributed. Akim Demaille suggested that eventually - # we switch to a new syntax: - # | Maybe we should take some inspiration from what's already - # | done in the rest of Automake. Maybe there is too much - # | syntactic sugar here, and you want - # | nodist_INFO = bar.info - # | dist_bar_info_SOURCES = bar.texi - # | bar_texi_DEPENDENCIES = foo.texi - # | with a bit of magic to have bar.info represent the whole - # | bar*info set. That's a lot more verbose that the current - # | situation, but it is # not new, hence the user has less - # | to learn. - # | - # | But there is still too much room for meaningless specs: - # | nodist_INFO = bar.info - # | dist_bar_info_SOURCES = bar.texi - # | dist_PS = bar.ps something-written-by-hand.ps - # | nodist_bar_ps_SOURCES = bar.texi - # | bar_texi_DEPENDENCIES = foo.texi - # | here bar.texi is dist_ in line 2, and nodist_ in 4. - # - # Back to the point, it should be clear that in order to support - # non-distributed .info files, we need to build them in the - # build tree, not in the source tree (non-distributed .texi - # files are less of a problem, because we do not output build - # rules for them). In Automake 1.7 .info build rules have been - # largely cleaned up so that .info files get always build in the - # build tree, even when distributed. The idea was that - # (1) if during a VPATH build the .info file was found to be - # absent or out-of-date (in the source tree or in the - # build tree), Make would rebuild it in the build tree. - # If an up-to-date source-tree of the .info file existed, - # make would not rebuild it in the build tree. - # (2) having two copies of .info files, one in the source tree - # and one (newer) in the build tree is not a problem - # because 'make dist' always pick files in the build tree - # first. - # However it turned out the be a bad idea for several reasons: - # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave - # like GNU Make on point (1) above. These implementations - # of Make would always rebuild .info files in the build - # tree, even if such files were up to date in the source - # tree. Consequently, it was impossible to perform a VPATH - # build of a package containing Texinfo files using these - # Make implementations. - # (Refer to the Autoconf Manual, section "Limitation of - # Make", paragraph "VPATH", item "target lookup", for - # an account of the differences between these - # implementations.) - # * The GNU Coding Standards require these files to be built - # in the source-tree (when they are distributed, that is). - # * Keeping a fresher copy of distributed files in the - # build tree can be annoying during development because - # - if the files is kept under CVS, you really want it - # to be updated in the source tree - # - it is confusing that 'make distclean' does not erase - # all files in the build tree. - # - # Consequently, starting with Automake 1.8, .info files are - # built in the source tree again. Because we still plan to - # support non-distributed .info files at some point, we - # have a single variable ($INSRC) that controls whether - # the current .info file must be built in the source tree - # or in the build tree. Actually this variable is switched - # off in two cases: - # (1) For '.info' files that appear to be cleaned; this is for - # backward compatibility with package such as Texinfo, - # which do things like - # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi - # DISTCLEANFILES = texinfo texinfo-* info*.info* - # # Do not create info files for distribution. - # dist-info: - # in order not to distribute .info files. - # (2) When the undocumented option 'info-in-builddir' is given. - # This is done to allow the developers of GCC, GDB, GNU - # binutils and the GNU bfd library to force the '.info' files - # to be generated in the builddir rather than the srcdir, as - # was once done when the (now removed) 'cygnus' option was - # given.
