argh, still more build errors on various fronts. i'm using ghc-6.6 on fedora core 5 unless otherwise noted. thanks in advance for help on any of these. a lot of this is part of my attempt to learn more about and play with a high-level functional gui library (and, of course, for getting a better grasp on what frp and arrows are all about) after realizing that i would never ever be able to get fruit working. i have so far found wxfruit (built on wxhaskell) and FG (built on gtk). i am interested in implementing a similarly 'highly-declarative' ui library built on hscurses.widgets. == wxhaskell-0.9.4 == $ make ... wx/src/Graphics/UI/WX/Types.hs:94:0: Bad interface file: out/wx/imports/Graphics/UI/WXCore/Types.hi Something is amiss; requested module wx:Graphics.UI.WXCore.Types differs from name found in the interface file wxcore:Graphics.UI.WXCore.Types make: *** [out/wx/imports/Graphics/UI/WX/Types.o] Error 1 == afrp-0.4 == after removing all references to packages 'lang' and 'concurrent' and changing all "import IORef" to "import Data.IORef as IORef": ghc -c -fglasgow-exts -O -o AFRPUtilities.o AFRPUtilities.hs AFRPUtilities.hs:169:46: Ambiguous occurrence `>>^' It could refer to either `>>^', defined at AFRPUtilities.hs:106:2 or `>>^', imported from AFRP at AFRPUtilities.hs:90:0-10 AFRPUtilities.hs:178:27: Ambiguous occurrence `>>^' It could refer to either `>>^', defined at AFRPUtilities.hs:106:2 or `>>^', imported from AFRP at AFRPUtilities.hs:90:0-10 AFRPUtilities.hs:184:46: Ambiguous occurrence `>>^' It could refer to either `>>^', defined at AFRPUtilities.hs:106:2 or `>>^', imported from AFRP at AFRPUtilities.hs:90:0-10 AFRPUtilities.hs:246:32: Ambiguous occurrence `^>>' It could refer to either `^>>', defined at AFRPUtilities.hs:103:2 or `^>>', imported from AFRP at AFRPUtilities.hs:90:0-10 AFRPUtilities.hs:247:33: Ambiguous occurrence `^>>' It could refer to either `^>>', defined at AFRPUtilities.hs:103:2 or `^>>', imported from AFRP at AFRPUtilities.hs:90:0-10 AFRPUtilities.hs:304:62: Ambiguous occurrence `>>^' It could refer to either `>>^', defined at AFRPUtilities.hs:106:2 or `>>^', imported from AFRP at AFRPUtilities.hs:90:0-10 == FG == $ ghc --make FG.hs [1 of 1] Compiling FG ( FG.hs, FG.o ) FG.hs:115:31: Module `Graphics.UI.Gtk' does not export `button' FG.hs:115:39: Module `Graphics.UI.Gtk' does not export `visible' when removing those two `hiding` params: [1 of 1] Compiling FG ( FG.hs, FG.o ) FG.hs:562:69: Couldn't match expected type `w' (a rigid variable) against inferred type `Bool' `w' is bound by the polymorphic type `forall w.
