[cl-opengl-devel] Hi to all :). Does anyone else have problems with ASDF2 and cl-opengl?
by Tomislav Tomsic 14 Oct '10

14 Oct '10

This being my first message here, greetings to you all :). I've just updated my sbcl on version 1.0.48.58,, and cl-opengl doesn't work. I am using it via clbuild on the Ubuntu 10.04 (64). This is the error message: 0: ((SB-PCL::FAST-METHOD ASDF:PERFORM (ASDF:COMPILE-OP ASDF:CL-SOURCE-FILE)) ..) 1: ((SB-PCL::EMF ASDF:PERFORM) #<unavailable argument> #<unavailable argument> #<ASDF:COMPILE-OP NIL {10045D16F1}> #<ASDF:CL-SOURCE-FILE "cl-opengl" "gl" "util">) 2: ((SB-PCL::FAST-METHOD ASDF::PERFORM-WITH-RESTARTS (ASDF:COMPILE-OP ASDF:CL-SOURCE-FILE)) ..) and so on. As I am able to discern, thanks to the numerous tries with various sbcl versions, yesterday and today, suddenly there is a problem with the file/resource locking, during the compilation. According to the sbcl documentation, that "feature" is in somewhat volatile state, and is the responsibility of the client software. To cut the story short, I think it is because of the new ASDF 2, that sbcl is starting to ship with. As such, I trust it will be resolved, sooner or later. In the meantime, does anyone have an idea for a workaround? Perhaps all that is needed is a slight change in the cl-opengl.asd, but I have no idea which one. At this moment, I am both unfamiliar with the newest asdf, as well as with the cl-opengl architecture. Once again, greetings to you all :) Respectfully Tomislav Tomsic

Does the documentation not exist yet, or am I just failing to generate it correctly?

Correct. lispbuilder-sdl is used with cl-opengl in this way. The example below shows lispbuilder-sdl creating the OpenGL context. http://article.gmane.org/gmane.lisp.cl-lispbuilder.general/648 -Luke

[cl-opengl-devel] no longer calling glut:init at load time
by Bart Botta 10 Aug '10

10 Aug '10

I disabled the call to glut:init when cl-glut is loaded, since it was breaking things that just want to load the code (to verify it compiles, check dependencies, build a binary, or whatever) but don't have a display available, and I'm guessing it wasn't helping with the threading problems on OSX either. If anyone runs into problems because of that, please file a bug or send a message to the list, so we can try to work out a better compromise between use-cases that need it initialized and those that need it not initialized. -b-

[cl-opengl-devel] cl-opengl in a standard X-window based canvas widget ?
by Kevin Smith 10 Aug '10

10 Aug '10

Has anyone used cl-opengl inside a standard X-window based drawing widget (one that supports simple refresh and input event call backs ) ? I am interested in bypassing GLUT (which I currently use) and using another lisp-based toolkit, potentially mcclim. I would like to continue using cl-opengl, though because I like it's interface. I am assuming that if I have a low-level window , I can create an OpenGL context for it and the cl-opengl binding would just work.

Re: [cl-opengl-devel] [Openmcl-devel] Trace/BPT trap with cl-opengl loading
by Kevin Smith 07 Aug '10

btw, I just tried the threaded version of sbcl (1.0.39) which I built from macports and it worked with no problems with all the same code (same cffi and cl-opengl packages), including my opencv libraries. I've not investigated what sbcl (or cffi) maybe doing that is different in this case, but it all seems to be working.

Are you running this on clozure 1.5 with Snow Leopard MAC OS (ie: version 10.6.4 ) ?

I had some chance to play around with this and got a little further, but not much... I added a hack in my code to do this as per the example file mentioned below... ;;;(use-foreign-library opengl) (eval-when (:compile-toplevel :load-toplevel :execute) (let* ((s (ccl:make-semaphore))) (ccl:process-interrupt ccl::*initial-process* (lambda () (ccl:open-shared-library "OpenGL.framework/OpenGL") (ccl:open-shared-library "GLUT.framework/GLUT") (ccl:signal-semaphore s))) (ccl:wait-on-semaphore s)) With this code, the shared libraries appear to load, but I do get the error message: kevin-mac-pro-3:lisp kevinsmith$ ccl64 ; loading system definition from /Users/kevinsmith/ccl-lisp/babel/babel.asd into #<Package "ASDF0"> ; registering #<SYSTEM BABEL> as BABEL ; loading system definition from /Users/kevinsmith/ccl-lisp/alexandria/alexandria.asd into #<Package "ASDF0"> ; registering #<SYSTEM :ALEXANDRIA> as ALEXANDRIA ; loading system definition from /Users/kevinsmith/ccl-lisp/trivial-features/trivial-features.asd into #<Package "ASDF0"> ; registering #<SYSTEM TRIVIAL-FEATURES> as TRIVIAL-FEATURES Welcome to Clozure Common Lisp Version 1.5-dev-r13523M-trunk (DarwinX8664)! ?

I created a stripped down version of my program that just has the cl-opengl and GLUT libraries in it and it looks like the first window comes up, but then it hangs before GL gets a chance to clear the window and do its thing...
