# Until Automake 1.6.3, .info files were built in the

# source tree. This was an obstacle to the support of
|
|
# non-distributed .info files, and non-distributed .texi
|
|
# 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_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. See automake bug#11034 for more discussion.

It appears this file (or files included by it) are triggering
