Update: I downloaded MinGW and MSYS and tried to install the GLUT library. I just can't get the thing to work, and I feel like I'm sitting in my own little section of Hell. I have tried everything I could think of so far, and it still doesn't work. Today I tried to sanitize my machine and start over. Here is my sequence of steps. Can anyone tell me what I'm doing wrong? -- Ron 1. Try to sanitize the machine. * Uninstall GHC, then delete C:\ghc and C:\Program Files\Haskell * Uninstall MSYS-DTK, MSYS, MinGW, then delete C:\MinGW and C:\MSYS * Verify that there is no glut*.dll in C:\Windows\System[32] * Delete C:\freeglut and C:\GLUT 2. Reboot. 3. Obtain the following files: Note: If I already downloaded a file, I saved it to avoid downloading again. [1] GHC windows executable http://haskell.org/ghc/dist/6.6.1/ghc-6.6.1-i386-windows.exe [2] FreeGlut http://superb-west.dl.sourceforge.net/sourceforge/freeglut/freeglut-2.4.0.ta... [3] Haskell GLUT library http://hackage.haskell.org/packages/archive/GLUT/2.0/GLUT-2.0.tar.gz [4] Automated MinGW installer http://downloads.sourceforge.net/mingw/MinGW-5.1.3.exe?modtime=1168811236&big_mirror=1 [5] MSYS: Minimal System installer http://downloads.sourceforge.net/mingw/MSYS-1.0.10.exe?modtime=1079444447&big_mirror=1 [6] MSYS: Supplementary Tools installer http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe?modtime=1041430674&big_mirror=1 [7] The RotatingCubes example, modified by adding an actionOnWindowClose in order to verify that FreeGlut is actually being used. http://hpaste.org/2632 3. Install GHC by running [1]. 4. Open a command window (Start->Run, type "cmd", click OK) 5. See what packages came with GHC. C:\Documents and Settings\Ron> ghc-pkg list C:/ghc/ghc-6.6.1\package.conf: Cabal-1.1.6.2, GLUT-2.1.1, HUnit-1.1.1, OpenGL-2.2.1, QuickCheck-1.0.1, Win32-2.1.1, base-2.1.1, cgi-3001.1.1, fgl-5.4.1, filepath-1.0, (ghc-6.6.1), haskell-src-1.0.1, haskell98-1.0, html-1.0.1, mtl-1.0.1, network-2.0.1, parsec-2.0, regex-base-0.72, regex-compat-0.71, regex-posix-0.71, rts-1.0, stm-2.0, template-haskell-2.1, time-1.1.1, xhtml-3000.0.2 ** Puzzle: Why does GHC have GLUT-2.2.1 if the latest verion of the GLUT library [3] is GLUT-2.0? 6. Try to run the modified RotatingCubes example [7], it should fail because I have neither GLUT not FreeGlut installed.
