Stefano,
Don't worry about the noise - I'm glad you solved your problem. The following
are some things that might help you or others in the future.
To run latest versions off of Jenkins on Ubuntu, I just dump the image,
changes, and Cog.zip contents into one directory and then have a one-line shell
script, something like this:
/home/bills/Pharo-1.4/CogVM /home/bills/Pharo-1.4/Seaside.image
------------- vm ---------------------- --------------------- image
--------------------
On Ubuntu at least, Cog looks for .so love in all the wrong places. The "best"
solution I have found (it's ugly) is to create sim links (in the common folder,
to wherever the library might be) to each library I want Cog to be able to see.
I have a plain text file called links.txt to help me. The first few lines are
ln -s /usr/lib/libplplotd.so.9 ./libplplotd.so.9
ln -s /usr/lib/libAccesIO-USB.so ./libAccesIO-USB.so
ln -s /lib/libc.so.6 ./libc.so.6
Faced with a new machine, I can simply issue these commands in a terminal to
make the libraries visible. AFAIK, what Cog should be doing (at least as a
first attempt to find a library) is to look for the library as named in
#moduleName. Ubuntu ties its dynamic loading of libraries to ldconfig's
"database," which anyone can read and only sudo can modify. It is s a clever
approach to the problem.
For example, on my machine, running
ldconfig -p | grep libplplotd.so.9
returns
libplplotd.so.9 (libc6) => /usr/lib/libplplotd.so.9
Asking to load libplplotd.so.9 will cause the system to load
/usr/lib/libplplotd.so.9. That is simply reading the map, which does not
require root access. If you want to add a library, you would either use
ldconf.d or simply place the library in usr/lib and then run (as sudo)
ldconfig, which scans the default locations and ldconfig.d scripts to rebuild
the database.
Right or wrong, this approach seems to work for me.
Bill

Ok, it was silly. Looking at the pharo.sh script made it clear.
Sorry for the noise.
Cheers,
