Same error here on OSX. I guess it is because we need to use the FreeType fonts instead of the default StrikeFonts. 2013/4/4 Jimmie Houchin <jlhouchin(a)gmail.com> > On 04/04/2013 11:34 AM, Igor Stasenko wrote: > >> On 4 April 2013 17:38, Jimmie Houchin <jlhouchin(a)gmail.com> wrote: >> >>> Hello, >>> >>> I am on Ubuntu 12.10 32bit. >>> >>> ...

On Ubuntu 12.10, I don't have a libcairo.so, but rather a libcairo.so.2 in /usr/lib/i386-linux-gnu. I created the link /usr/lib/libcairo.so as expected by Pharo, and it works. Now, when I get to screen 30, I enabled FreeType as instructed but I am getting an error MNU: StrikeFont>>glyphRenderOn: Thanks again. Jimmie

Esteban, Having a new Browser in Pharo 2.0 is a big change. Everyone needs to get used to it. And I agree it is probably a good thing. But â¦ there are some things that worked better in OB that I don't want to loose. There are a lot of people annoyed by how it works nowâ¦. but I think the mailing list is about exchanging arguments not about deciding. So I do not like that you try to end the discussion by shouting: the defaults will not change. So here I will add a new argument. Your argument about other languages is a valid point, but only holds if Smalltalk is similar as other languages. Why does this "enter" annoys me? Because in some cases it replaces my code by garbage. At least when I type a method invocation that does not exist yet, it replaces it by an existing method. And this is repeatable. So when you go back (using backspace and typing it again, because it also adds before the things I typed) and the press enter again, it does the same replacement. So there is a difference here between smalltalk and other languages. When I do test-driven development (that I do a lot), I first write my test, invoking a lot of methods that do not exist yet. I do not do this in another language, because my environment isn't good enough then.

aptitude is old (some kind outdated) and I have had several problems with it. we should always recommend to use apt-get instead :) Esteban On Apr 4, 2013, at 5:38 PM, Jimmie Houchin <jlhouchin(a)gmail.com> wrote: > Hello, > > I am on Ubuntu 12.10 32bit. > > I have followed the directions below for the Tutorial. > > After the bash script completed it gave me these instructions. > > Please install the 32bit libraries > sudo aptitude install ia32-libs > > I typed the above into the terminal and was told that I do not have "aptitude" installed. > > I changed "aptitude" to "apt-get" and then was instructed that I do not have ia32-libs. > I went to the Ubuntu Software Center.

Re: [Pharo-project] [FYI] Athens tutorial

by Jimmie Houchin

Hello, I am on Ubuntu 12.10 32bit. I have followed the directions below for the Tutorial. After the bash script completed it gave me these instructions. Please install the 32bit libraries sudo aptitude install ia32-libs I typed the above into the terminal and was told that I do not have "aptitude" installed. I changed "aptitude" to "apt-get" and then was instructed that I do not have ia32-libs. I went to the Ubuntu Software Center. What is on Ubuntu 12.10 is ia32-libs-multiarch. sudo apt-get install ia32-libs-multiarch works. I then open the image and proceed with loading the code and the tutorial. I skip page 1 and "doit" on page 2 and I get this error. Error: failed to get a symbol address: cairo_image_surface_create As far as I can tell, I have Cairo installed on my system. I have libcairo2. I don't know if I am missing something or what I need to do. I haven't successfully done anything that I am explicitly aware that used NB that has worked on this system. I have just a standard Ubuntu 12.10 32bit install. I have the build-essential libraries. Just wanted to provide some input. Let me know if there is something I need to install or what I can do to help.
