[cl-opengl-devel] get-tex-image not external?
by Malcolm Reynolds 23 Feb '10

23 Feb '10

Hi >>> Try the version at http://github.com/3b/cl-opengl I'm using this github branch you pointed me to and it's been working very well so far, so thanks for going to effort to keep the package updated for Snow Leopard. A minor point I've come across is that get-tex-image doesn't seem to be external, is there any particular reason for this / is there some interface I should be accessing it through? I couldn't find one with a quick bit of grepping.. Cheers, Malcolm

[cl-opengl-devel] Problems running cl-openl on Snow Leopard
by Malcolm Reynolds 15 Feb '10

Hello all, I'm having issues getting cl-opengl working on Snow Leopard 10.6.2. I definitely had some working Lisp OpenGL stuff on my previous laptop (plain old Leopard) but the switch to SL seems to have caused a show stopper (maybe something to do with 64 bits?). I'm using SBCL 1.0.35.2, compiled myself from git. I haven't enabled threads because they are a bit shaky on Mac, and I've specifically compiled a 32 bit version because I have some 32 bit libraries I'd like to link to. I'm using the latest version of cl-opengl from darcs. I open up a new lisp, load :cl-glut-examples using ASDF, and then move into the package and try to run a demo (for the sake of argument #'RB-HELLO although this appears to happen with everything) and the lisp dies with this fairly cryptic error message: * (in-package :cl-glut-examples) #<PACKAGE "CL-GLUT-EXAMPLES"> * (rb-hello) 2010-02-15 16:33:44.197 sbcl[766:903] GLUT Warning: invalid glutGet parameter: 124 Mon Feb 15 16:33:44 mreynolds-mbp.local sbcl[766] <Error>: kCGErrorInvalidConnection: CGSGetCurrentCursorLocation: Invalid connection Mon Feb 15 16:33:44 mreynolds-mbp.local sbcl[766] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

I'm digging through the code right now but I'm by no means skilled at opengl or lisp so it's hard going.. Many thanks, Malcolm
