I have test, and found new error:
------------------------------> error start <------------------------------
Resolving dependencies...
Configuring gtk-0.10.5...
Preprocessing library gtk-0.10.5...
Building gtk-0.10.5...
Module imports form a cycle for modules:
Graphics.UI.Gtk.Abstract.Object
(dist/build/Graphics/UI/Gtk/Abstract/Object.hs)
imports: Graphics.UI.Gtk.Signals
Graphics.UI.Gtk.Signals (dist/build/Graphics/UI/Gtk/Signals.hs)
imports: Graphics.UI.GtkInternals
Graphics.UI.GtkInternals (dist/build/Graphics/UI/GtkInternals.hs)
imports: Graphics.UI.Gtk.Multiline.Types
Graphics.UI.Gtk.Multiline.Types
(dist/build/Graphics/UI/Gtk/Multiline/Types.hs)
imports: Graphics.UI.Gtk.General.Structs
Graphics.UI.Gtk.General.Structs
(dist/build/Graphics/UI/Gtk/General/Structs.hs)
imports: Graphics.UI.Gtk.Abstract.Object
cabal: Error: some packages failed to install:
gtk-0.10.5 failed during the building phase. The exception was:
ExitFailure 1
------------------------------> error end <------------------------------
Above error casuse i modified Signal.chs.template to make Signal.chs import
`Graphics.UI.Gtk.General.Threading`.
So put "Graphics.UI.Gtk.General.Threading" in GtkInternals is not good
idea, and cycle problem in GHC is *big* trouble.
So can we just simple expose module `Graphics.UI.Gtk.General.Threading`
for Signal.chs? And write notes "don't use Graphics.UI.Gtk.General.Threading
module".
Just set "x-Types-Forward: *Graphics.UI.GtkInternals" let Types.chs use
GtkInternal.
What do you think?
