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)?
You should not need X-Windows.
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”
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.
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
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.
