# 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.)
|
|
#
|
|
# 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 has been installed there; if
|
|
# it's not, it won't find the GLib autoconf macros, and will complain
|
|
# bitterly.
|
|
#
|
|
# So, 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 return a "-I"
|
|
# flag with the first of those directories as the argument.
|
|
#
|
|
# (If they *are* the same directory, 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.)
