Re: [Pharo-users] Oneiric gone bad

You guys rock! I spent about 90 mins searching on the web this morning and only found vague hints that didn't make much sense. Post the question on here, have a shower, drive to work, read the answers, fire up the package manager, select the libs, press 'apply', run Pharo. Job done. Oeniric gone good :-) Thank you both. -- View this message in context: http://forum.world.st/Oneiric-gone-bad-tp3938304p3938643.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

The driver vm-display-X11 is a dynamic library, which is shipped by default with VM, there is _no way_ how VM could not find it. The problem is that this library depending on another libraries in system which could be missing, and because of that, when VM attempts to load it, OS reports an error, and then VM says that its unable to find the driver, while actually it is unable to load it. > Any ideas? > > -- > View this message in context: http://forum.world.st/Oneiric-gone-bad-tp3938304p3938304.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > > -- Best regards, Igor Stasenko.

also need this one now in oneiric: sudo apt-get install ia32-libs-multiarch:386 As least, on a clean install I did. And assuming you're using the 64-bit version. If you're using the 32-bit version I don't know what to try. -- View this message in context: http://forum.world.st/Oneiric-gone-bad-tp3938304p3938605.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Oneiric gone bad

by Jeff Gray

Just updated Ubuntu and now Pharo doesn't run. I have been working ok under Oneiric but then after getting the latest update Pharo no longer runs. If I drop into the terminal and try to fire up the VM I get the following: jeff@Roger:/usr/local/lib/cogvm$ ./squeakvm could not find display driver vm-display-X11; either: - check that /usr/local/lib/cogvm//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted Any ideas? -- View this message in context: http://forum.world.st/Oneiric-gone-bad-tp3938304p3938304.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

That doesn't mean the whole thing is that complicated. I never tried Nicks stuff but I'm sure in nearly all cases it will take 10 minutes to get going. If you just want to host a gemstone application and you are not in a hurry it might be good to wait a little bit. The gemstone guys are in the progress to integrate GLASS services into cloud foundry [1]. There you will be able to deploy your application and only that. You won't have access to the underlying operating system but that means you don't need to care. If you need to do more integration stuff on the machine than there are a few options. Nicks machine is the best right now IMHO. I myself have developed some scripts that help dealing with some setup things of GLASS [2]. And we are building a bootstrapp chain for a GLASS appliance where you could build your own machine from scratch [3] (which is in very early state and could cause more than 60 messages :) ).

Hosted GLASS made easy?

by Larry White

Hi, I've been watching a thread on the Seaside mailing list about hosting GLASS on Amazon's EC2. It hit 60 messages (try this, doesn't work, try that...). I'm no sys admin, so I'd like to find cloud hosting for pharo and Gemstone that is easier to manage. I got Gemstone & Pharo running on my mac in just a few hours, but i'm sure that's a lot easier than a manual install on someone else's remote linux box with Apache etc. Is there a reliable cloud hosting environment where the GLASS virtual appliance might 'just work' out of the box? thanks.
