squeak on ubuntu linux

Liliana-2

Hi,

 

We have an Intel dual core 64 bit server where we installed Ubuntu 7.04

We are all new in Squeak/Smalltalk; but we managed to develop a small Seaside app in Squeak (on Windows XP) using Squeak 3.9 and Seaside 2.7 (latest).

We would now like to install this image on the linux server and run seaside there, under Apache.

I read quite a few of posts and Ramon Leon’s blog on how to get a squeak/seaside headless vm working on Linux; but we are all but confused; and didn’t manage to get anywhere.

Questions:

1.       Do we need x-windows, or not (we will not do development on the linux server)?

2.       Is there a squeak vm we can download  or do we have to build from source for Intel dual-core? ( we tried both versions and neither works)

The debian packages at:

 http://ftp.squeak.org/debian/ stable main

don’t seem to work for linux running on intel dual core and we downloaded Squeak-3.9-8.i686-pc-linux-gnu.tar.tar from http://www.squeakvm.org/unix/

 

With this last one installed we get the error:

“could not find module vm-display-X11”

When we run:

squeak -headless groupinvestment.image

(where groupinvestment.image is our Windows build image containing seaside and our web site)

 

And when we run:

squeak -nodisplay groupinvestment.image

we get:

Segmentation fault

This means that the VM cannot find that module (to state the obvious...
sorry!); try copying that module (vm-display-X11.la or
vm-display-X11.so) into the same directory as the squeak executable.
Alternatively, you may be having linking problems because you're using
32-bit binaries. While Squeak won't use this plug-in, for some reason it
won't start unless it is present.

I would recommend trying the 64-bit binaries:
http://www.squeakvm.org/squeak64/. I have used this version of Squeak on
an AMD-64 machine without any problems.

Also note that Squeak currently can't use the dual cores; for now Squeak
can only make use of one core. I don't know about running multiple
images with a load balancer though to increase thoughput; I don't think
that Seaside would support this because it keeps stateful sessions.

I will let somebody else on this list handle this. It may be related to
trying to run a 32-bit binary on a 64-bit machine.

Michael.

Also - you'll need a way to manage Squeak remotely.

I recommend either using the Squeak VNC server (should be on SqueakMap?)
which many people have had success with, or the REPLServer which is a
telnet server that runs simple Smalltalk commands - an old version is on
SqueakMap, or I've made a nicer version at
http://www.squeaksource.com/SecureSqueak/REPL-mvdg.13.mcz.

Michael.

Hi Michael.

Thank you for your reply so far...

>>I would recommend trying the 64-bit binaries:
>>http://www.squeakvm.org/squeak64/. I have used this version of Squeak on
an AMD-64 machine without any problems.

This site has Squeak3.8g-6548...
I understand that our 3.9, 32bit, image should not run under this squeak
anyway?
We did try that build. I can't remember the errors we've got; but it didn't
work. We could try it again and report the errors if need be..

Kind regards,
Liliana

Yes, please report those errors so we can help you further.


The VM version does not need to match the Image version. In fact, at the
moment I'm running a Squeak VM version 3.3 on my PDA with the 3.8 image,
and it works fine.

The 64-bit VM can run both 32-bit images and 64-bit images. Unfortunately,

I can't remember how this worked. If I remember correctly, you could compile
two binaries - one for 32-bit images and one for 64-bit images.

I also believe that the 64-bit VM was originally made because the 32-bit

VM didn't work at all on 64-bit architectures. Can anybody else confirm
this?

Also make sure that you have the ia32-libs Ubuntu package installed - 
this may magically make the 32-bit VMs work.


Michael.
