[Pharo-project] Running Pharo on a headless Ubuntu server

by Jan van de Sandt

Hello, I am trying to run a Pharo Seaside image on an Ubunbtu 10.04 server. When I start the image like this squeak -mmap 256m -vm-sound-null -vm-display-null seaside3.0rc.image I get the following errors: found gettext in path /srv/seaside libasound.so.2: cannot open shared object file: No such file or directory squeak: could not find any display driver /usr/bin/squeak: line 277: 7499 Aborted $VM "$1" "$2" Does anybody know the minimal set of packages I need to install before I can run a headless image? Jan.

now :) I still would like the non jitted VM to be used to kick us to optimize. Especially since on specific devices the JIT may not exist or be forbidden. Stef

I tested pharo-core 1.2 as well as a seaside image based on pharo 1.1 with Glorp and PostgreSQL: everything worked as expected. I did a quick benchmark on that last image: where I used to get 70 requests/second I now get 230 requests/second. This is really amazing. Thanks Eliot, John and everybody else who made this possible. I hope the linux VM is equally fast. Sven

Thanks John. It seems this is even a little faster (at least with tinyBenchmarks) than the image produced by Eliot john 10 tinyBenchmarks '721126760 bytecodes/sec; 55015015 sends/sec' 10 tinyBenchmarks '717589348 bytecodes/sec; 55483560 sends/sec' 10 tinyBenchmarks '706206896 bytecodes/sec; 55562428 sends/sec' eliot 10 tinyBenchmarks '626682986 bytecodes/sec; 54326849 sends/sec' 10 tinyBenchmarks '625152625 bytecodes/sec; 54251448 sends/sec' 10 tinyBenchmarks '630153846 bytecodes/sec; 54326849 sends/sec' A difference I found with Eliot VM and your previous ones is shortcuts. In eliot image, to select words, I do shift + ctrl + narrow, or shift + command + narrow. In yours, I only can do shift + command + narrow. And if I do shift + ctrl + narrow the mouse cursos doesn't even move. cheers mariano On Thu, Aug 26, 2010 at 12:12 AM, John M McIntosh < johnmci(a)smalltalkconsulting.com> wrote: > I've stuck a version (5.8b3) of the cocoa based os-x squeak cog JIT based > VM in my experimental folder. > > http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b3.app.zip > > This VM is built from the Cog sources (with some minor changes for the > iPhone) & revised & fixed Socket Plugin. > It currently does NOT contain any external plugins.
