[cl-opengl-devel] cl-glut not able to open windows until shown how by lispbuilder-sdl
by Zach Hall 07 Aug '12

07 Aug '12

Hi everyone, I'm having a weird problem with cl-glut. When I run something using glut to produce a window, I don't get a window. Inserting a swank-handler into the loop of the examples, I determined that they WERE running, they just weren't giving me a window. I'm using Windows 7, Clozure-CL and I have FreeGlut loaded and detected properly. Everything works, except that the window doesn't show. So! I decided to try Lispbuilder-SDL, I loaded up their examples and they are able to successfully open windows. What's really odd about this, is that AFTER I've created a window using Lispbuilder, it seems to show Glut what to do, and Glut can suddenly open display windows properly. Does anyone have any idea what could be causing this?

> You need FreeGLUT rather than classic GLUT. Thanks, that was the last piece of the puzzle. For the record, the entire set of steps I went through was: File->Load-> C:\Lisp\Tools\quicklisp.lisp - only needs to be done once. or CL-USER 1 : 1 > (load #p"C:/Lisp/Tools/quicklisp.lisp") CL-USER 1 : 1 > (quicklisp-quickstart:install) - only needs to be done once. CL-USER 2 > (load #p"c:/documents and settings/username/quicklisp/setup.lisp") needs to be done every time in LispWorks Personal Edition, which doesn't support init files. CL-USER 3 : 1 > (ql:quickload :cl-opengl) CL-USER 4 : 1 > (ql:quickload :cl-glut-examples) CL-USER 5 : 1 > (cl-glut-examples:list-examples) CL-USER 6 : 1 > (cl-glut-examples:gears)

Well, to partially answer my own question :) I was thinking that quicklisp downloaded everything it need, not realizing that GLUT is a separate library. I found a Windows binary glut32.dll here: http://www.opengl.org/resources/libraries/glut/ However - their installation instructions consist of copying the glut32.dll to C:\windows\system32. Which I did. But how do I tell Lispworks to *find* that dll? Thanks again. John C>

Thanks for the replies, I'm making progress. However, it still isn't loading, and I'm not sure if it's a missing library, or maybe miscompiled, or what. The steps I've done so far are: (quicklisp-quickstart:install) - worked (ql:quickload "cl-opengl") - worked (ql:quickload :cl-glut-examples) - fails with this output: ====================== CL-USER 6 > (ql:quickload :cl-glut-examples) To load "cl-glut-examples": Load 1 ASDF system: cl-glut-examples ; Loading "cl-glut-examples" Error: Unable to load foreign library (GLUT). Could not register handle for external module GLUT: The specified module could not be found.. ==================== Yet everything *looks* like it's there: CL-GLUT 26 : 2 > (ql:system-apropos "glu" + "cffi" + "opengl") #<QL-DIST:SYSTEM cl-glfw-glu / cl-glfw-20120703-git / quicklisp 2012-07-03> #<QL-DIST:SYSTEM cl-glu / cl-opengl-20120520-git / quicklisp 2012-07-03> #<QL-DIST:SYSTEM cl-glut / cl-opengl-20120520-git / quicklisp 2012-07-03> #<QL-DIST:SYSTEM cl-glut-examples / cl-opengl-20120520-git / quicklisp 2012-07-03> #<QL-DIST:SYSTEM cffi / cffi_0.10.7.1 / quicklisp 2012-07-03> #<QL-DIST:SYSTEM cl-opengl / cl-opengl-20120520-git / quicklisp 2012-07-03> Any ideas on while it's failing to load? Thanks. John C>

(cl-glut-examples:list-examples) lists the available examples which you can run individually. There's also a run-examples function which runs all examples simultaneously.

How do I install and run the demo code? I'm running Lispworks PE 6.01 on Windows, I've installed quicklisp and ran: (ql:quickload "cl-opengl") which seemed to download the library. But so far I haven't managed to run the demo examples. Thanks. John C>

[cl-opengl-devel] Documentation status?
by John Crawford 03 Aug '12

Looking back through the archives, I see a post in 2010 about the documentation not yet having created. Is that still the case? If it *does* exist (or can be created), how/where would it be? Thanks. John C>
