3 # This script returns the flags to be fed to "aclocal" to ensure that
4 # it finds GTK+'s aclocal macros.
6 # aclocal will search, by default, only in a directory in the same
7 # tree where it was installed - e.g., if installed in "/usr/bin", it'll
8 # search only in "/usr/share/aclocal", and if installed in "/usr/local/bin",
9 # it'll search only in "/usr/local/share/aclocal".
11 # However, there is no guarantee that GTK+ has been installed there; if
12 # it's not, it won't find the GTK+ autoconf macros, and will complain
15 # So, if the "share/local" directory under the directory reported by
16 # "gtk-config --prefix" isn't the same directory as the directory
17 # reported by "aclocal --print-ac-dir", we return a "-I" flag with
18 # the first of those directories as the argument.
20 # (If they *are* the same directory, and we supply that "-I" flag,
21 # "aclocal" will look in that directory twice, and get well and truly
22 # confused, reporting a ton of duplicate macro definitions.)
