Subject:    -6- Priism won't start; what can I do?

  There are a number of things to check depending on whether or not
  the system has told you anything about why it failed.  The paragraphs
  that follow cover the more easily handled situations.


  If you see a message like "Priism: Command not found", the environment
  (specifically the PATH environment variable) is not correctly
  set so Priism can be found.  A message like 

    rld: Fatal Error: Cannot Successfully map soname libIWL.so ...

  on IRIX or

    Priism: error in loading shared libraries: libIWL.so ...

  on Linux is also a likely indicator that your environment (the 
  LD_LIBRARY_PATH variable on IRIX and LINUX; the DYLD_LIBRARY_PATH
  environment variable on MacOS X) is not set correctly.  In either
  case you should talk to the person who installed Priism and ask
  him or her what you should do.  If you are the person who installed
  Priism, running post_install.sh should correctly set these paths
  in the Priism_setup file:  for more details consult the installation
  instructions at

    <http://msg.ucsf.edu/IVE/IVE4_HTML/PriismInstallation.html>

  (for IVE 4) or

    <http://msg.ucsf.edu/IVE/Download/PriismInstallation.html>
 
  (for IVE 3.3).


  Another thing that can prevent Priism from starting is if a previous
  Priism session failed to delete its shared memory file.  Priism 4.1.6
  and later are better at dectecting the dead session and avoiding the
  problem.  For all versions, you can run ivekill from the command line
  to delete the shared memory file.
