somewhere other than GLib (or if GLib isn't installed at all; that configure script will fail in that case, but that's better than failing because PKG_CHECK_MODULES wasn't defined, as that's a confusing failure mode). svn path=/trunk/; revision=36635

# 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.
