|
||
# files.
|
||
#
|
||
# * Non-distributed .texi files is important in some packages
|
||
# where .texi files are built at make time, probably using
|
||
# other binaries built in the package itself, maybe using
|
||
# tools or information found on the build host. 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_TEXINFO = foo.texi
|
||
# nodist_foo_TEXINFO = 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
|
||
# want to distribute .texi files, but do 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 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
|
