Re: [Pharo-users] libGLU.so.1: cannot open shared object file: No such file or directory

by laurent laffont

Hi, did you check that libGLU.so.1 is actually on your system ? It should be in /usr/lib/libGLU.so.1 If not, check that package mesa is installed. I'm not using OpenSuse but that's how it works on ArchLinux and Debian.

libGLU.so.1: cannot open shared object file: No such file or directory

I'm using Pharo for the first time as a beginner. My O/S is $ uname -a Linux shevek 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux which is OpenSuSE 11.2 I downloaded and unzipped Pharo-1.1-OneClick.app with this result: $ pwd /home/greg/Play/Lang/Special/Pharo/Pharo-1.1-OneClick.app $ ./pharo.sh libGLU.so.1: cannot open shared object file: No such file or directory could not find module vm-display-X11 Aborted However, the module does seem to exist: $ find . -name '*vm-display-X11*' ./Contents/Linux/so.vm-display-X11 I look forward to running Pharo and sharing it with my friends when it comes up reliably for newbies like me on Gnu/Linux - something which Squeak has not yet achieved!

Re: [Pharo-users] Disabling Fractions ?

by Hernan Wilkinson

you should do that... one thing is how your model works and another is how it shows the results to a human (display, printer, etc)... so if you have a number renderer or something like that, you do asFloat there... but that is not enough, you will have to decide how many decimals you want to show, etc. so it is better to use #printShowingDecimalPlaces: and problem solved :-) On Sat, Jul 31, 2010 at 4:54 PM, Stanislav Paskalev <kshorg(a)gmail.com>wrote: > Purely for display.

Now i'm working on Pharo 1.2 so I now use PluggableTextMorph, but then it doesn't work on 1.1 anymore (because of the styler). I've also added two NullObject class to simulate stylers so if a real styler exist it choose it, else it choose the nullstyler. I will add a droplist in the System >> Setting to change the default styler class :) Ben

Hi ben on which version should I load it? It is important that recentMessages works without shout. I got a DNU on 1.2 buildTextArea | text | text := PluggableShoutMorph on: self text: #textToDisplay accept: #compileMethod: readSelection: nil menu: #msgPaneMenu:shifted:. text visible: false; askBeforeDiscardingEdits: true. ^ text Stef On Jul 31, 2010, at 9:29 PM, Benjamin Van Ryseghem wrote: > > Ok...I did it.
