Next: Make sure that the build environment is configured properly, Up: How to compile the java package in Octave?
Check whether the java package is already installed by issuing
the pkg list
command:
octave> pkg list Package Name | Version | Installation directory --------------+---------+----------------------- java *| 1.2.8 | /home/octavio/octave/java-1.2.8 octave>
If the java package appears in the list you must uninstall it first by issuing the command
octave> pkg uninstall java octave> pkg list
Now the java package should not be listed anymore. If you have used the java package during the current session of Octave, you have to exit and restart Octave before you can uninstall the package. This is because the system keeps certain libraries in memory after they have been loaded once.
