with a fresh check out gdk doesn’t get installed. I installed it with
ruby 2.0. Programs started fail with:
cannot load such file – gdk3 (LoadError)
With the “make install” the gdk3 and the gdk3-no-gi directories where
not entered. Compiling gdk3 with
ruby extconf.rb gdk3
fails, cause the gdk3 directory doesn’t has the extconf.rb file.
Compiling gdk3-no-gi directly works.
