still trying
by Andre Furtado 05 Feb '03

05 Feb '03

I'm feeling a bit frustrated (and perhaps stupid... :-]) for not being able to figure out the solution for my HOpenGL compilation problems... I really wonder why cygwin doesn't recognize a simple command like "ghc --version" anymore, and insists that I need to put a ".exe" suffix when trying to run every executable file (i.e., "ghc.exe --version" works). In the ./configure step, I get the message "No Haskell compiler not found" and I'm sure it is not related to the PATH, since it is set correctly. Perhaps this ".exe" problem has something to do with the error... Previous attempts to reinstall cygwin (including removing it from windows98 register and installing it again) were not successful: the ".exe" problem still happens. I followed all steps in http://www.pms.informatik.uni-muenchen.de/mitarbeiter/panne/cygwin/opengl_gl ut.html and previous emails, but I think I'm stuck in something earlier. Any suggestions are highly welcome, as always. Cheers, -- Andre

Installation von HOpenGL-1.04
by Jan Rochel 04 Feb '03

04 Feb '03

Hi, Why does `make install' not install the directories in $SRC/GLUT/Graphics containing *.hi files to $GHC/imports/HOpenGL/Graphics? I can only compile the examples when I do that manually after the installation. Greets Jan

ANNOUNCE: HOpenGL 1.04 released
by Sven Panne 22 Jan '03

22 Jan '03

HOpenGL, a Haskell binding for OpenGL and GLUT version 1.04 I am pleased to announce the fifteenth release of the Haskell binding for GL 1.2.1 / GLU 1.3 / GLUT 3.7beta. It offers easy access to *the* industrial strength 3D graphics API and a GUI toolkit. More details about HOpenGL can be found at http://haskell.org/HOpenGL After quite some time, this is not only a bugfix release, but offers some real improvements and new features. The changes include: * The GLUT binding has been completely rewritten and includes extensive documentation. * The API for quadrics and tessellation has been made much easier and more Haskell-like. * The configuration process has been improved once again. * The license is now BSD-like. * At least GHC 5.04.x is needed for building HOpenGL. * NURBS has been temporarily disabled (will be fixed soon). As always, feedback and/or patches are highly welcome. Have fun! Sven

divide the display in subwindows
by mai99dnn＠studserv.uni-leipzig.de 21 Jan '03

21 Jan '03

Hi there. I want to divide my window into subwindows to display different informations (like Nate Robins in his OpenGL Tutorials, if anyone knows). So I try to work out his solution in Haskell. My Main.hs has the following structure: main :: ... mainWin<-createWindow.. reshapeFunc (Just mainReshape) displayF... mainDisplay sub1<-createSubWindow mainWin ... reshapeFunc (Just sub1Reshape) ... -- here follows the interesting part -- in the mainReshape Nate Robins call the subReshapes... mainReshape :: ReshapeAction ... ... setWindow sub1 --!!! no sub1-Window in there :-( positionWindow (...) reshapeWindow (...) ----------------------------------------------------------------- its clear that sub1 isnt known in the mainReshape. In C you can define global variables to solve this. Is that in Haskell possible too? I can't give the sub1 Window directly to the mainReshape (mainReshape :: Window -> Resh..) because when the funtion is called in the main this sub1 isnt created yet (see above). I hope this was a clear description of the dilemma I'm in. And I pray, that I'm just too stupid and the solution is much more clearer to you. Thanx a lot Patrick

HOpenGL port for FreeBSD
by Jan Rochel 18 Jan '03

18 Jan '03

Hi, This concerns those, who use or want to use HOpenGL with FreeBSD. I wrote a HOpenGL port for FreeBSD, but it's not yet in the FreeBSD ports collection, since it has been tested only on my system. I'd be glad if you'd test it, so I can submit it as soon as possible. It's located at http://kungens.kemi.fi/~shae/haskell/hs-HOpenGL.tar.gz Download, extract it in /usr/ports/graphics and `make install'! Of course, you'll let me know any bugs, critics and recommendations... Thx Jan

I only succeeded after this. make scripts are supposed to use X11/GL, which I wasn't able to configure. You must use Win32/Opengl libraries. >From previous post of Sven: * In HOpenGL's configure, replace the line '#ifndef GL_VERSION_1_2' with something like '#ifndef ThisIsVeryUnlikely'. This is because cygwin headers doesn't show their actual version. do: ./configure make depend Find 'config.mk' and replace references to X11/GL libraries with win32 ones: [-lglut, -lGLU, -lGL, ...] -> [-lglut, -lglu32, -lopengl32] In redbook_C/Makefile.linux, comment CFLAGS var, cygwin gcc doesn't work it. I copied .h headers to any include dir in the tree :) Finally, try 'make all' ___________________________________________________ Yahoo!

What does it mean? This is a conflict between the way gcc is configured on Mandrake and the way we need to use it for GHC. There is a proper fix in CVS for the problem, but a workaround is to add the flag -optc-mno-omit-leaf-frame-pointer to the GHC command line. (I haven't actually tested this, but it *should* work - please let me know). Cheers, Simon

Check this weird history: I was stuck at "make install" getting the error: GL/glut.h: No such file or directory I then copied the glut files from http://haskell.org/HOpenGL/releases/OpenGL-includes.zip and passed through this point. Later in "make install", I got a new error: test -d "/cygdrive/c/GHC/GHC-5.04.2/BIN/ghc/imports/HOpenGL" || mkdir "/cygdrive /c/GHC/GHC-5.04.2/BIN/ghc/imports/HOpenGL" mkdir: cannot create directory `/cygdrive/c/GHC/GHC-5.04.2/BIN/ghc/imports/HOpen GL': No such file or directory make[1]: *** [install] Error 1 make: *** [install] Error 1 I created the missing directory by hand and finally "make install" was completed, in spite of a lot of warnings such as: - foreign declaration uses deprecated non-standard syntax - assignment discards qualifiers from pointer target type - implicit declaration of function `glTexImage3D' - ... I did not understand why the examples (both C and HS) were not compiled during stall. I then tryied to compile them by hand, but got stuck at BlendEqn with the following error: ../../lib/libHOpenGL.a(GL_PerFragment__57.o)(.text+0x124)://c/WINDOWS/TEMP/g hc-3 33765.hc: undefined reference to `glBlendEquation' make[1]: *** [BlendEqn] Error 1 make: *** [all] Error 1 I then decided to start it all over again (once more :]) because I realized that I copied glut files AFTER the ./configure step, and supposed that this could give me more problems in the future. When running "./configure" once more, I was very surprised by this error: checking for ghc... no configure: error: No Haskell compiler not found (!!!) Now I have no idea what am I supposed to do... perhaps uninstall everything (including GHC) and try it once more. As always, config.log is attached, in case someone can give me a light.

Starting it all over again: It works!!!
by Manuel Garcia Rodriguez 10 Jan '03

10 Jan '03

Hello. Thanks God! After three weeks I was able to compile and run HOpenGL. There are a lot of mails in my digest about this topic, I'll try to reply all simultaneously :). I can't assure this steps are the only ones because my installation has a week of incremental changes. This is intended to work with Cygwin + GHC 5.04.2 + GreenCard 2.04 on WinXP SP1. I have a full install of cygwin, but I suppose this is not necessary. To get it working I follow this steps (after a million failures): - install cygwin, ghc... - Unzip the GL headers, missing in GHC: http://haskell.org/HOpenGL/releases/OpenGL-includes.zip in GHC dir - Follow the steps in http://www.informatik.uni-muenchen.de/~Sven.Panne/cygwin/opengl_glut.html I've installed precompiled files only (.a). Finally I ran the test and GLUT works (!!!). Maybe it works all this time, I don't know. - ./configure && make depend - Open 'config.mk' generated by ./configure, and add/replace X11/gl lib list [-lGLU, -lGL...] with win32 ones: [-lglut, -lglut32, -lglu32, -lopengl32...] - comment the CFLAGS=-L/usr/x11r6/lib. It seems that cygwin gcc doesn't like... If you get headers missing, copy them to some default dir (maybe /usr/include) - make all - make install when everything worked I was disturbed more than the first time that failed After this nightmare, I have drawn some conclusions: - OpenGL libraries that works (for me) are WIN32 dlls (HW accel???). All the time I thinked I was working with X11/GL. - Install scripts doesn't work under cygwin (for me), I think these are fixed to X11/GL, that doen't work (by default) on cygwin. Thanks everybody for help. You'll get more news next week (Simon). Manuel. ___________________________________________________ Yahoo!
