How to set library path for UFFI on Linux?

by Dan Wilczak

I've just installed the 64-bit version of Pharo 6.1 on OpenSuse linux (64 bit). The Athens demos fail because UFFI looks for libcairo in /usr/lib rather the /usr/lib64. I tried setting LD_LIBRARY_PATH but that has no effect. How can I force it to use lib64? Dan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] X11 options on Ubuntu VM / Athens rendering problems

by Stephane Ducasse

Hi Jeff Nice to see you. I do not know anybody running on X11. Esteban is working on better SDL20 integration. Did you try having a native window? I asked clement if he could release the Wizard Battle Arena because it was a game he did in a couple of days (yes he is good this guy) and that use cairo athens based for drawing on native window. stef On Fri, Sep 22, 2017 at 3:11 PM, J.F.

The repository can be found on smalltalk hub. Here are also load instruction: http://smalltalkhub.com/#!/~DiegoLont/QCMagritte/ I just checked loading in pharo 6 (after making a fix) of: Gofer new url: 'http://smalltalkhub.com/mc/DiegoLont/QCMagritte/main'; package: 'ConfigurationOfQCMagritte'; load. ((Smalltalk at: #ConfigurationOfQCMagritte) project version: #'development') load. (Smalltalk at: #ZnZincServerAdaptor) startOn: 8080 And this allows me to start the tutorial. It seems not all versions load yet, so I need to do some more work on the configuration, but this will be next week. Regards, Diego P.S. QC stands for the company it was originally build for. I do not know exactly where the initials stand for â¦ as it was already an historic name at that time. > On 22 Sep 2017, at 13:35, H.

X11 options on Ubuntu VM / Athens rendering problems

by J.F. Rick

I'm running a fullscreen Pharo application on Ubuntu and I've noticed that Athens rendering gets way worse (maybe 10 updates per second) when I switch to fullscreen mode from inside Pharo. Ideally, I'd love for that to be fixed. In lieu of that, it would be cool if I could just maximize Pharo to the size of the screen to achieve good performance. Two things stop that: the Unity application bar and the title-bar. For the former, I can configure Unity to hide it. I noticed a '-notitle' X11 option when I execute pharo -help. I've tried using these X11 options and neither -notitle or -fullscreen seem to have any effect. Here's the command I run: ./bin/pharo --encoding utf8 -vm-display-X11 -fullscreen PATH_TO_IMAGE & Pharo starts fine but neither option seems to have any effect. I've also tried this in GNOME, thinking that Unity was the problem. Again, no effect. Any suggestions? Jeff
