Thanks for the ideas. I guess I'll stick with #1 for now, but I documented the others and appreciated the interesting conversation :) ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Pharo-Mars on Ubuntu

by kmo

Thanks for the suggestion but everything is 64 bit. I added this problem to the mars github issues list (there's an existing issue for linux problems) and Esteban is now looking at it, so we're getting somewhere. The problem was I had no libgit-3.so in the folder only a libgit.so.0. Unfortunately adding a symbolic link hasn't solved my problems. I now get a VM crash. I've reported this along with the crash dump. I'm sure it will be sorted eventually but I've been trying to get mars to run on ubuntu since May - so progress is slow. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

The most common cause of things like this seems to be running a 32-bit program and only having the 64-bit libraries available. Is your Pharo VM 32-bit?

Pharo-Mars on Ubuntu

by kmo

I've just tried to get pharo-mars working on xubuntu 20.04. But it tells me it cannot find the GTK3 library. But the library is present here: /usr/lib/x86_64-linux-gnu/libgtk-3.so.0 I thought this was supposed to be the correct place. Should I be putting a symbolic link somewhere? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
