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.

Ok, it was silly. Looking at the pharo.sh script made it clear. Sorry for the noise. Cheers, Stefano On Mon, Mar 26, 2012 at 5:13 PM, stefano franchi <stefano.franchi@gmail.com> wrote:

Dear all,

this may be a silly question, but I can't find the answer in the pharo book or on the list:

how do you start pharo on a specific image? in Visualworks, you'd do

$vw imagename

and from then on, the image and change file would be saved in imagename's directory.

But in pharo, it seems the imagename I give on the command line is ignored, and I always start with the default image (which, on my archlinux system, is located at /usr/share/pharo). Since that directory is not writable by default and it contains the change file, I get all sort of errors. Perhaps it is an installation issue?

Cheers,

Stefano
