HOpenGL && --enable-threaded-rts
by Tim Docker 27 Feb '03

I'm trying to bring HOpenGL up on my new gentoo linux box. It all built fine, but any OpenGL program that tries to create a window SEGVs immediately after... OpenGL on them machine seems to work OK - I can compile and run teapots.c from the distribution for example. (Not to mention run tuxracer :-) I noted a long thread last year about --enable-threaded-rts and HOpenGL not working togther. The thread did not seem to end in a solution. The default ebuild of ghc for gentoo has this flag turned on. Might this be the cause of my problems? I was suprised when I run the SEGVing program under gdb to find that there were multiple threads in operation. Tim

GLUT problems...
by Andre W B Furtado 25 Feb '03

25 Feb '03

I'm VERY HAPPY to report that I finally installed HOpenGL successfully with windowsXP. Now some more interesting problems are arising... :) I'm trying to compile FunGEn again, and notices some differences in the GL/GLU/GLUT structure: GLUT does not belong to HOpenGL's lib anymore, it has its own directory instead... So wich would be the correct way to modify my Makefile in order to include GLUT? Should I use an option like -i../HOpenGL-1.4/GLUT or something like that? I don't like the idea at all, since Makefile becomes dependent of the HOpenGL directory... any suggestions? Thanks, -- Andre

HOpenGL-1.03 on WinDoze, step by step...
by Sven Panne 24 Feb '03

24 Feb '03

Some people seem to have quite some trouble with HOpenGL 1.03 on WinDoze, so here's a step-by-step recipe: * First of all, use GHC 5.04.2. Older versions might work, but this one contains a lot of bug fixes. * Alas, the OpenGL/GLUT headers were accidentally left out from the WinDoze installer for GHC 5.04.2, so add the missing headers by simply unzipping http://haskell.org/HOpenGL/releases/OpenGL-includes.zip into your GHC installation directory. * The headers on WinDoze are sometimes cheating about the actual OpenGL version. This can be fixed by applying the first patch attached below * If you want to build HOpenGL with MinGW/MSYS: * HOpenGL's build system didn't take MinGW/MSYS into account, but this can easily be fixed by applying the second patch attached below. * MinGW/MSYS comes without a GLUT header, so unzip glut.h from http://haskell.org/HOpenGL/releases/OpenGL-includes.zip into MinGW\include\GL\. * MinGW/MSYS comes without a GLUT DLL, so copy http://haskell.org/HOpenGL/releases/glut32.dll into MinGW\bin\. The DLL is taken from Cygwin, BTW. * If you want to build HOpenGL with Cygwin: * Apart from the default packages, you need Graphics/opengl, Devel/gcc, and Devel/make. * Building with Cygwin's XFree86 packages is currently untested, but you don't need them for HOpenGL anyway. * You don't have to do anything special to get HW acceleration, the OpenGL DLL takes care of that automatically by using your video card's DLL(s) provided by the card's vendor. Hope that helps, S. ---------------------------------------------------------------------- --- HOpenGL-1.03.orig/configure Mon Jul 29 17:33:03 2002 +++ HOpenGL-1.03/configure Sat Jan 18 16:32:35 2003 @@ -4130,7 +4130,10 @@ ac_status=$? echo "$as_me:4131: \$? = $ac_status" >&5 (exit $ac_status); }; }; then - hopengl_cv_gl_version=1.2 + case `uname | tr a-z A-Z` in + CYGWIN*|MINGW*) hopengl_cv_gl_version=1.1 ;; + *) hopengl_cv_gl_version=1.2 ;; + esac else echo "$as_me: failed program was:" >&5 cat conftest.$ac_ext >&5 ---------------------------------------------------------------------- --- HOpenGL-1.03.orig/lib/find-ghc-libdir Sun Jul 21 12:19:15 2002 +++ HOpenGL-1.03/lib/find-ghc-libdir Sat Jan 18 16:28:43 2003 @@ -52,7 +52,7 @@ if test "$IS_CYGWIN" = "no" ; then case `uname | tr a-z A-Z` in - CYGWIN*) IS_CYGWIN=yes ;; + CYGWIN*|MINGW*) IS_CYGWIN=yes ;; *) ;; esac fi ----------------------------------------------------------------------

installtion hopengl

Hello! It's my first post sent to this group, and my question is about installation. Do you know some site where I can find detailed information about this? I've installed cygwin and green-card, and I think that I have all is needed to install HOpenGL. When I run the configure file on cygwin, happens an error that blocks the process, and this error is related with gcc (C compiler). It say that the C compiler (gcc) can't createexecutables Can you help me?? Thanks! Marcelo Pita marcelopita(a)ibest.com.br Icon - Internet grátis, e-mail, MP3 player, vídeo, rádio e muito mais.

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
