Run "ghc-pkg check", and do a "cabal install --reinstall" for all
packages that it says need to be rebuilt at the bottom.

This gets a little hilarious (but better to laugh than cry).
Well, I decided to try Parsec version 3 (i.e., 3.1.0) after all, and edited my cabal config to include:
preference: parsec >= 3
I did not include "base >= 4"; hope that is not a problem.
I did "cabal upgrade parsec", which went great.
It added the new dirs:
...\cabal\parsec-3.1.0 ...\cabal\mtl-1.1.1.0 ...\cabal\bytestring-0.9.1.7
I recompiled my little parsec demo.hs using various appropriate Text.Parsec modules (instead of Text.ParserCombinators.Parsec), and it worked great. Wonderful!
So, I tried to recompile another program I have that uses:
module Main where import Control.Monad.Trans ( liftIO ) import Data.IORef import Graphics.UI.Gtk import Graphics.UI.Gtk.Gdk.GC import Graphics.UI.Gtk.Gdk.EventM import Graphics.UI.Gtk.Glade import List ( delete, nub )
For this code (which previously compiled okay):
on canvas exposeEvent $ do -- drawWindow <- eventWindow -- region <- eventRegion liftIO $ do -- <<< this is line 135 updateCanvas canvas currentPattern pattern2CanvasOffset zoomFactor id (w,h) <- widgetGetSize canvas -- get (width,height) of DrawingArea putStrLn $ "DrawingArea redrawn; (width, height) = " ++ show (w,h) return True
I get:
life.hs:135:6: No instance for (Control.Monad.Trans.MonadIO (mtl-1.1.0.2:Control.Monad.Reader.ReaderT (GHC.Ptr.Ptr EExpose) IO)) arising from a use of `liftIO' at life.hs:135:6-11 Possible fix: add an instance declaration for (Control.Monad.Trans.MonadIO (mtl-1.1.0.2:Control.Monad.Reader.ReaderT (GHC.Ptr.Ptr EExpose) IO)) In the first argument of `($)', namely `liftIO' In the expression: liftIO $ do { updateCanvas canvas currentPattern pattern2CanvasOffset zoomFactor id; (w, h) <- widgetGetSize canvas; putStrLn $ "DrawingArea redrawn; (width, height) = " ++ show (w, h); return True } In the second argument of `($)', namely `do { liftIO $ do { updateCanvas canvas currentPattern pattern2CanvasOffset zoomFactor id; (w, h) <- widgetGetSize canvas; .... } }'
When I did: "ghc --make life.hs -v", I saw among the output:
"hiding package mtl-1.1.0.2 to avoid conflict with later version mtl-1.1.1.0"
I guess that the parsec upgrade installed the newer mtl, and I'm wondering if that is what is making life.hs fail to compile. (?)
Silly me, I noticed my gtk package was not up to date:
* gtk Synopsis: Binding to the Gtk+ graphical user interface library. Latest version available: 0.11.2 Latest version installed: 0.11.0 <<< Homepage: http://www.haskell.org/gtk2hs/ License: LGPL-2.1
So!, thinking it might help, I did: "cabal upgrade gtk" too. (In the past I have successfully done "cabal install gtk", so I thought this would be okay. :-) I got:
H:\proc\dev\cmd>cabal upgrade gtk Resolving dependencies... Configuring old-time-1.0.0.5... cabal: The package has a './configure' script.

The exception was: ExitFailure 1 pango-0.11.2 depends on old-time-1.0.0.5 which failed to install. process-1.0.1.3 depends on old-time-1.0.0.5 which failed to install.
(This is where I began laughing instead of crying :-)
I don't recall ever having problems with old-time in the past.
If anyone has any suggestions, I would appreciate it.
I am willing to either keep parsec 3 and resolve the life.hs compile errors, or to revert to parsec 2 and somehow undo my package installation problems. (E.g., is there a "cabal uninstall <package-version>" command?)
Thanks again very much. -- Peter
p.s., trying to compile the parsec 3 demo yields (sorry about the formatting):
