Re: [Pharo-project] FFI on 1.3: compile fields

Another glitch: is there any problem passing things as void*? I'm getting failure to coerce errors that did not arise before. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] on behalf of Igor Stasenko [siguctua(a)gmail.com] Sent: Wednesday, February 29, 2012 5:51 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] FFI on 1.3: compile fields On 1 March 2012 00:37, Schwab,Wilhelm K <bschwab(a)anest.ufl.edu> wrote: > Does 1.3 by default not create field accessors?

Re: [Pharo-project] fun with NBOpenGL

woow... it is always fun to see that something which looks like trash (who can be impressed by a stupid rotating cube today?) can be turned into piece of art with a few keystrokes, just by taking right pictures :) And that's why it is soo fun to work with graphics. -- Best regards, Igor Stasenko.

Does 1.3 by default not create field accessors? Why is that? I thought nothing was happening. Bill

It's really fun. I Promise, Steph i work on the paper tomorrow but it 's so fun ^^. Current step, MultiTexturing object use key for moving the cube (arrow for turn the cube). next Step Full Control of Camera (just add translation). And generate full land of cube. Textures by Kaeliss ^^ : http://kaeliss.deviantart.com/ Brain: We must prepare for tomorrow night. Pinky: Why? What are we going to do tomorrow night? Brain: The same thing we do every night, Pinky - try to take over the world!

Re: [Pharo-project] leaking semaphores

by Igor Stasenko

I find it funny, that your "interference" is actually root of all problems :) I don't know much about RFBServer , the only thing i know is that it is quite old (not in terms that it rusty, but in terms of it existence). Can't say what happens, but probably on terminating connection it does some nasty/incompatible things.
