3199 # * Non-distributed .texi files is important in some packages
3200 # where .texi files are built at make time, probably using
3201 # other binaries built in the package itself, maybe using
3202 # tools or information found on the build host. Because
3203 # these files are not distributed they are always rebuilt
3204 # at make time; they should therefore not lie in the source
3205 # directory. One plan was to support this using
3206 # nodist_info_TEXINFOS or something similar. (Doing this
3207 # requires some sanity checks. For instance Automake should
3209 # dist_info_TEXINFOS = foo.texi
3210 # nodist_foo_TEXINFOS = included.texi
3211 # because a distributed file should never depend on a
3212 # non-distributed file.)
3214 # * If .texi files are not distributed, then .info files should
3215 # not be distributed either. There are also cases where one
3216 # wants to distribute .texi files, but does not want to
3217 # distribute the .info files. For instance the Texinfo package
3218 # distributes the tool used to build these files; it would
3219 # be a waste of space to distribute them. It's not clear
3220 # which syntax we should use to indicate that .info files should
3221 # not be distributed. Akim Demaille suggested that eventually
3222 # we switch to a new syntax:
3223 # | Maybe we should take some inspiration from what's already
3224 # | done in the rest of Automake. Maybe there is too much
3225 # | syntactic sugar here, and you want
3226 # | nodist_INFO = bar.info
3227 # | dist_bar_info_SOURCES = bar.texi
3228 # | bar_texi_DEPENDENCIES = foo.texi
3229 # | with a bit of magic to have bar.info represent the whole
3230 # | bar*info set. That's a lot more verbose that the current
3231 # | situation, but it is # not new, hence the user has less
3234 # | But there is still too much room for meaningless specs:
3235 # | nodist_INFO = bar.info
3236 # | dist_bar_info_SOURCES = bar.texi
3237 # | dist_PS = bar.ps something-written-by-hand.ps
3238 # | nodist_bar_ps_SOURCES = bar.texi
3239 # | bar_texi_DEPENDENCIES = foo.texi
3240 # | here bar.texi is dist_ in line 2, and nodist_ in 4.
3242 # Back to the point, it should be clear that in order to support
3243 # non-distributed .info files, we need to build them in the
3244 # build tree, not in the source tree (non-distributed .texi
3245 # files are less of a problem, because we do not output build
3246 # rules for them). In Automake 1.7 .info build rules have been
3247 # largely cleaned up so that .info files get always build in the
3248 # build tree, even when distributed. The idea was that
3249 # (1) if during a VPATH build the .info file was found to be
3250 # absent or out-of-date (in the source tree or in the
3251 # build tree), Make would rebuild it in the build tree.
3252 # If an up-to-date source-tree of the .info file existed,
3253 # make would not rebuild it in the build tree.
3254 # (2) having two copies of .info files, one in the source tree
3255 # and one (newer) in the build tree is not a problem
3256 # because 'make dist' always pick files in the build tree
3258 # However it turned out the be a bad idea for several reasons:
3259 # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
3260 # like GNU Make on point (1) above. These implementations
3261 # of Make would always rebuild .info files in the build
3262 # tree, even if such files were up to date in the source
3263 # tree. Consequently, it was impossible to perform a VPATH
3264 # build of a package containing Texinfo files using these
3265 # Make implementations.
3266 # (Refer to the Autoconf Manual, section "Limitation of
3267 # Make", paragraph "VPATH", item "target lookup", for
3268 # an account of the differences between these
3270 # * The GNU Coding Standards require these files to be built
3271 # in the source-tree (when they are distributed, that is).
3272 # * Keeping a fresher copy of distributed files in the
3273 # build tree can be annoying during development because
3274 # - if the files is kept under CVS, you really want it
3275 # to be updated in the source tree
3276 # - it is confusing that 'make distclean' does not erase
3277 # all files in the build tree.
3279 # Consequently, starting with Automake 1.8, .info files are
3280 # built in the source tree again. Because we still plan to
3281 # support non-distributed .info files at some point, we
3282 # have a single variable ($INSRC) that controls whether
3283 # the current .info file must be built in the source tree
3284 # or in the build tree. Actually this variable is switched
3285 # off for .info files that appear to be cleaned; this is
3286 # for backward compatibility with package such as Texinfo,
3287 # which do things like
3288 # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
