Re: [Pharo-users] Pharo 2.0 on Fedora 18

by Mariano Martinez Peck

Hi Edwin. I wrote some details on how to install Pharo in CentOS for a client. I paste them here in case it may help you: --------------------------- Installing Pharo in CentOS is not difficult. However, it does require some packages and dependencies. Pharo will only work with 32 bits libraries, therefore, we need to download them. [edit<http://debrispublishing.com/wiki/index.php?title=Infrastructure:Installing_…> ]Get Pharo You can get the Pharo from http://www.pharo-project.org/pharo-download. To install it you just need to uncompress it. [edit<http://debrispublishing.com/wiki/index.php?title=Infrastructure:Installing_…> ]Installing 32 bits needed libraries To install the minimal needed libraries, we can execute: sudo yum install libX11.i686 libX11-devel.i686 mesa-libGL.i686 mesa-libGL-devel.i686 To test if the VM works, just execute the following with a demo.image: ./pharo xxx.image And there shouldn't be any error in the console. [edit<http://debrispublishing.com/wiki/index.php?title=Infrastructure:Installing_…> ]Installing OpenSSL If we plan to use Zodiac or SSL we have to install openSSL 32 bits libraries. To do that: sudo yum install openssl098e.i686 openssl.i686 sudo cp /usr/lib/libssl.so.0.9.8e /usr/lib/libssl.so.0.9.8 Notice the second line is because otherwise Pharo fails to link to /usr/lib/libssl.so.0.9.8. To test if the link is correct, do: ldd /opt/pharo/pharoVM/libSqueakSSL.so And you should see something like: libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00291000) Otherwise, there is a problem in the link. Now, all Zodiac and Zinc-Zodiac tests should be green.

Re: [Pharo-users] Pharo 2.0 on Fedora 18

by Esteban Lorenzano

Hi, That's a hard reference, sadly. You need to install 0.9.8 (32bits) in your distribution. I don't know how to do it in fedora, but on ubiuntu is usually plain simple... probably in fedora is also available with the apt-get equivalent tool :) cheers, Esteban On Aug 5, 2013, at 6:43 AM, edwin ancaer <eancaer(a)gmail.com> wrote: > Hello, > > I'm running Pharo 2.0 on Fedora 18.

Re: [Pharo-users] Does zinc support server sent events?

Sven said >>> Assuming you mean http://en.wikipedia.org/wiki/Server-sent_events the answer is no or not yet. It doesn't look very complicated though, given the fact that Zinc WebSockets do already work. I will start by reading the specs. <<< Sounds great! Please let me know if I can help in any way.

Re: [Pharo-users] New version of PharoSound

by kmo

I've always wanted to try sound out in Pharo - just for fun. But I've never had even a squeak (pardon the pun) out of Pharo. This is all the more strange since Pharo comes from Squeak and Squeak was touted as a multimedia system and I remember having sound on Squeak when I first looked at it years ago. So, seeing how a new PharoSound has just turned up in the configuration browser in Pharo 2 Summer, I thought at last I was in luck. But no. Still no sound here on Linux. SoundPlayer boinkScale gives a primitive failure on primSoundAvailableBytes. No noise comes from SoundDemoMorph or PianoKeyboardMorph. Can anyone gove me a simple recipe for getting sound to work. I'm on a vanilla Pharo 2.0 Summer on Ubuntu 13.04 32 bit (actually, xubuntu). Thanks. -- View this message in context: http://forum.world.st/New-version-of-PharoSound-tp4702032p4702091.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
