Back on opengl win32 again? no window
Ok, sorry to bring this back up again. I asked before and kind of went to a working linux system. My question; On Win32, has anyone seen where you try to run the application but the window will not stay open. There are no errors, the window with 3D objects will not stay open. I was using a recent haskell 6.6.1 (ghc-6.6.1- i386-windows.exe). I asked before it seemed like the others suggested I use freeglut and use that. But I dont really need freeglut extensions. I am using basic opengl. I noticed that opengl is included in the ghc (mingw) I downloaded. Also, the code compiles, just doesnt run. The machine itself is a 3.2ghz, nvidia machine (win2k). I know opengl code should work. You can see the source here: http://octanemech.googlecode.com/svn/trunk/octanemech/src/misc/camera/ I compiled with: ghc --make MechCamera.hs -prof -auto-all -o $@ Basically the initialization aspect: import Graphics.Rendering.OpenGL import Graphics.UI.GLUT import Data.IORef mechLaunchGLWindow = do getArgsAndInitialize -- Initialize with the following settings -- Double buffer, RGBA color -- Alpha components supported, Depth buffer initialDisplayMode $= [ DoubleBuffered, RGBAMode, WithDepthBuffer, WithAlphaComponent ] initialWindowSize $= Size mechScreenWidth mechScreenHeight createWindow mechWindowTitle mechInitGL let mainCamera = initCamera (1.4, 4.2, -4.5) (0,0,0) (0,0,0) mainMech = initMech (0, 0, 0) (0, 0, 0) mainCameraRef <- newIORef(mainCamera) mainMechRef <- newIORef(mainMech) -- Set the OpenGL callbacks displayCallback $= displayGameLoop mainCameraRef mainMechRef -- Set the keyboard callback for handling actions keyboardMouseCallback $= Just (mechKeyPressed mainCameraRef) idleCallback $= Just idle mainLoop -- Berlin Brown [berlin dot brown at gmail dot com] http://botspiritcompany.com/botlist/?

Ok, I made a little bit more progress. I was able to get the OpenGL source compiled, on a windows environment. I was able to compile libHS* but now I don't know what exactly I should do with it. I guess my next would be to actually link it to the haskell runtime. Hopefully this may help others. Building stuff from the darcs/haskell repo: Open cygwin, I am using a recent version (Download cyg Oct 20, 07). I did have to install "autoconf tools" with the cygwin installer. I am behind a firewall/proxy so I had to set this at the command line export http_proxy=SOME_PROXY:9999 darcs get http://darcs.haskell.org/packages/OpenGL/ cd to that OpenGL directory. Here are the commands I invokved. autoreconf ./configure ghc --make Setup.hs ./Setup configure ./Setup build ./Setup build install After everything was built, you should see the following output (towards the end). (from $ ./Setup build install) Setup.exe: Warning: Unknown field 'build-type' Preprocessing library OpenGL-2.2.1... Building OpenGL-2.2.1... /usr/bin/ar: creating dist\build\libHSOpenGL-2.2.1.a Only bad thing, I don't really know what to do with libHSOpenGL-2.2.1.a. I guess I should have used "--prexix" at the configure command. I avoided that because of the nature of cygwin paths. Is there a manual way to copy what was output from this build. Manually, I changed libHSOpenGL-2.2.1.a to libHSOpenGL.a and copied to my ghc runtime. That didn't seem to do anything as I finally ran my application and got the same result. Next? I downloaded freeglut 2.4 and get compile errors. I dont know I need to compile that or not. -- Berlin Brown [berlin dot brown at gmail dot com] http://botspiritcompany.com/botlist/?
