Re: pil64emu, OpenGL?
Hi Jon, hi Jorge, I suggest, in lib/openGl.l, to replace (default *GluLib libGLU.so *GlutLib libglut.so ) with (if (= *OS Darwin) (default *GluLib Frameworks/OpenGL.framework/OpenGL *GlutLib Frameworks/GLUT.framework/GLUT ) (default *GluLib /usr/lib/libGLU.so *GlutLib /usr/lib/libglut.so ) ) It works like a dream on my iMac! Exactly why I can leave out /System/Library/ as Jorge suggested, I'm not sure, but it works. Hmm, the more I think about it, the more I agree with you both. Though keeping the library path out of the way is somewhat cleaner, it is tedious to use. I've put the above into lib/openGl.l.

Re: pil64emu, OpenGL?
Just a note, the Frameworks/ part is irrelevant. Looks like it uses just the 2 last components of the path (OpenGL.framework/OpenGL). I have changed it to /foo/bar/OpenGL.framework/OpenGL and it works the same.

Hi, I suggest, in lib/openGl.l, to replace (default *GluLib libGLU.so *GlutLib libglut.so ) with (if (= *OS Darwin) (default *GluLib Frameworks/OpenGL.framework/OpenGL *GlutLib Frameworks/GLUT.framework/GLUT ) (default *GluLib /usr/lib/libGLU.so *GlutLib /usr/lib/libglut.so ) ) It works like a dream on my iMac!

I consider pil64emu as finished. Here OpenGL works already since last week. I tried, for example, your pyramids.l (also attached to this mail): ./pil pyramids.l + (default *GluLib /usr/lib/libGLU.so *GlutLib /usr/lib/libglut.so ) From what I can see, there's no libglut.so to be found on my Mac. I thought it worked previously on pil32? Cheers, - Alex A long time ago we had OpenGL stuff working with pil32 on Mac, by using my library (which has been available externally from http://folk.uio.no/jkleiser/pico/gl.tgz). That library no longer builds or works with more recent pil32 versions (on Mac). Re. pil64, that one has never worked on Mac. I did use pil64 a bit on Ubuntu via VirtualBox on Mac. So where/how can one then obtain libglut.so (and libGLU.so) for use on Mac, if they are required? /Jon -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe

I don't know what to do on the Mac, but as a generalization I changed the above two default lines in lib/openGl.l to (default *GluLib libGLU.so *GlutLib libglut.so ) i.e. I removed the absolute paths. This should make it less dependent on the specific system installation. Works well here. Any objections? Cheers, - Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
