Installation FAQ

  • Period04 only starts with an empty Window on Linux Systems when Desktop Effects are enabled:

    • Open the file .bashrc in your home directory and add the line:
      export AWT_TOOLKIT=MToolkit
      Save and restart bash by typing 'bash'. This should make the Period04 Interface visible.


  • Error 'JAVA_HOME missing':

    • If you haven't done so already, install Java (java.sun.com/getjava).

    • If you see this message although Java is properly installed this means that the variable JAVA_HOME is still not defined on your system. To set this variable using the bash shell, follow these steps:

      (i) Locate your Java directory (it usually contains the folders 'bin', 'jre', 'lib',...). Let us suppose your Java home directory is '/usr/java/jdk1.5.0_01'.

      (ii) Open the file '.bashrc' in your user directory with an editor. At the end of the file, append the line:
      export JAVA_HOME=/usr/java/jdk1.5.0_01
      Save and close the file.

      If you do not want to edit '.bashrc' you can alternatively replace the $JAVA_HOME string in the 'period04' file by the path to your Java home directory (enter 'whereis period04' to find this file) .
