It really needs a configuration :-) You mean a configuration like the one I attached :) Did you notice the new "Config+" button on the metacello browser - it helps creating new configs. I also added a postload for plugin registration. Feel free to use and put into your STHub repo. I found two bugs in Periscope using Pharo2.0 #20627: 1. When one enters "Obj" to search for object it crashes in the spotlight 2. When one opens tools like the Configuration browser they show up inside of the area of Periscope... If this gets fixed and config gets usable for Pharo 2.0 then do not forget to add the updated config also to "MetaRepoForPharo20" on SS3. This way it will show up in the config browser and can easily be loaded. Thx T.

Gisela contacted me, and I managed to load the newest version. AST-Core is changed in Flamel by adding instance variables to RBProgramNode. That breaks each time AST-Core changes in Pharo. Still 2 failing tests (already on Trello), and the transformation needs work. Stephan

Its fixed by adding the missing 't' to mac32PlaformId, becoming mac32PlatformId. I think your image is outdated ... That is a really old bug.

Looking at the code I notice that it looks for libGL.so under /usr/lib/libGL.so. In modern versions of 64 bits Ubuntu, and Linux Mint which is derived from Ubuntu, libGL.so is not placed under /usr/lib, instead is placed in a driver dependent folder, which is referenced by a config file in /etc/ld.so.conf.d/ . With a mesa driver, the OpenGL library is at /usr/lib/i386-linux-gnu/mesa/libGL.so.1 , so the driver shared object path cannot be hardcoded. The path problem is a know issue, yes. If you have a good solution. But yes basically you have to update manually the pass in the moduleName variable. > Changing the module name for 'libGL.so.1', doesn't work, but changing it for '/usr/lib/i386-linux-gnu/mesa/libGL.so.1' gives me an 'unable to resolve external type: GLXDrawable', adding NBGLXTypes into the pool dictionaries of NBGlxAPI solves it. I fix that too. > After changing that, it tries to create a multisampled framebuffer, however it doesn't check the maximum number of samples supported. My machine reports GL_EXT_framebuffer_multisample as supported, but the FBO created is not complete. I modified the creation code to use only 1 sample for multisampling and its works. > Using those hacks makes it work under a 64 bits Linux. Still, whenever I run an example, I'm getting a top level window that doesn't does nothing, which is annoying.

Current 3.0 download is broken

Hi all, I wanted to toy around with 3.0 for a moment today, so I downloaded the last image from http://files.pharo.org/image/30/Pharo-Image-3.0-latest.zip It is unresponsive with 100% CPU usage. I thought it was a VM issue of mine, so I downloaded the installer , and this has the same issue. I This is MacOS, I'm still on 10.8.5, I attach PharoDebug.log below for your perusal Greetings, ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Who uses poolDictionaries? New class template cleanup
by Johan Fabry Nov. 14, 2013

Nov. 14, 2013

Hi all, I am preparing slides for a course. I came to the typical: Number subclass: #Complex instanceVariableNames: 'real imaginary' classVariableNames: '' poolDictionaries: '' category: 'ComplexNumbers' Which made me think: Who uses poolDictionaries? I suspect extremely few of us. Why not add this to Class: Class>>subclass: aSymbol instanceVariableNames: instVarNames classVariableNames: classVarNames category: aSymbol ^self subclass: aSymbol instanceVariableNames: instVarNames classVariableNames: classVarNames poolDictionaries: '' category: aSymbol And have the new class template as follows? Object subclass: #NameOfSubclass instanceVariableNames: '' classVariableNames: '' category: 'Kernel-Classes' It would be a bit cleaner. I know us old timers don't even see the poolDictionaries: line anymore, but I dislike having to explain it to students.
