Is your DISPLAY environment variable set?  If so, does the Xserver
allow you to connect to it?

  And the answer is yes in both cases.

        DISPLAY is set to localhost:0.0 (from 'echo $DISPLAY')

        'xterm &' results in an xterm window.

  Some additional info that may be relevant: the tutorials work fine in command 
line mode.

Thanks for the quick reply.

I had the same problem when I tried to run a simulation from my linux 
box at home, while Swarm and the simulation was compiled in 
university unix box.
Are you "in front" of the computer in which is installed Swarm?
If not, you have to set your DISPLAY variable.
( the exact commands are
from your computer you have to write
xhost +
while from a shell of the other computer you have to write
setenv DISPLAY=yourIP:0:0
then run you simulation)
Hope this help.

  See above and, yes, I am "in front" of the computer on which Swarm is 
installed.

Thanks to both!


  AND from Paul Johnson:


It is necessary to install Swarm in order to use Swarm :)

swarm-static is not swarm, that is statically compiled libraries.

You need: ...

  I am currently in the process of installing gcc3 ...

  But I am confused. I thought Swarm WAS 'libraries' that were used by the sim 
developer to
develop a simulation application.

Thanks for the help and pointers on where to get all the necessary support S/W.
