Hi, I'm a Haskell newbie. I've been studying Haskell by reading the book The Haskell School of Expression. Most of the example in the book use graphics library SOEGraphics. Windows GHC didn't find the library, but I assumed that the new name for the library is Graphics.SOE which seemed to properly loaded. The problem is that I fail to get the Graphics library to work properly. Instead GHC freezes if I use the graphics library in interactive mode and if I compile into a binary the binary freezes. The problem is not only with Graphics.SOE but also with more general Graphics.HGL. If I execute the Hello World program presented in Graphics.HGL documentation front page, GHC interactive mode freezes after opening the window but before drawing any text on the window. Compiled binary never even opens a window but freezes before that. Examples in HSOE (the book) behave the exactly the same way. I get not error messages what so ever. The example I refer to above is below. module Main where import Graphics.HGL main :: IO () main = runGraphics $ withWindow_ "Hello World Window" (300, 200) $ \ w -> do drawInWindow w $ text (100, 100) "Hello World" drawInWindow w $ ellipse (100, 80) (200, 180) getKey w The question is what I could be doing wrong or is Graphics library just incompatible with my environment. I'm using GHC 6.4.2 on Windows XP SP2. I've been developing using Eclipse 3.2 with EclipseFP plugin. However I've also tried to compile on command line. Could somebody help me over (no I'm not moving to Linux...)
