#
# This script returns the flags to be fed to "aclocal" to ensure that
# it finds GLib's aclocal macros (we assume GTK+ is installed in the
# same place as GLib) and pkg-config's aclocal macros.
#
# aclocal will search, by default, only in a directory in the same
# tree where it was installed - e.g., if installed in "/usr/bin", it'll
# search only in "/usr/share/aclocal", and if installed in "/usr/local/bin",
# it'll search only in "/usr/local/share/aclocal".
#
# However, there is no guarantee that GLib, or pkg-config has been installed
# there; if either of them hasn't been installed there, aclocal won't find
# the autoconf macros for whichever of them wan't, and will complain
# bitterly.
#
# So:
#
# if pkg-config is found with a path that ends with "bin/pkg-config",
# and the "share/local" directory under the directory at the path
# that's the part of the pkg-config path preceding "bin/pkg-config"
# isn't the same directory as the directory reported by "aclocal
# --print-ac-dir", we include in our output a "-I" flag with that
# directory as its argument;
#
# if the "share/local" directory under the directory reported by
# "pkg-config --variable=prefix glib-2.0" isn't the same directory
# as the directory reported by "aclocal --print-ac-dir", we include
# in our output a "-I" flag with the first of those directories as
# the argument.
#
# If either of them *is* the same directory as the directory reported by
# "aclocal --print-ac-dir", and we supply that "-I" flag, "aclocal" will
# look in that directory twice, and get well and truly confused, reporting
# a ton of duplicate macro definitions. This also means that if pkg-config
# and Glib are installed with the same prefix, we should only supply one
# "-I" flag for both of them.
#
#
# OK, where will aclocal look by default?
#
aclocal_dir=`aclocal --print-ac-dir`
