Scenario: When using Ubuntu Trusty (14.04.3LTS) Gephi 0.82 initializes but gets stuck on “Loading Cached Objects”
Solution: The default Gephi startup bash script does not correctly initialize the JAVA path (it uses $jdkhome) The solution is simply to add the following to the beginning of the startup script (~/gephi/bin/gephi)
export JAVA_HOME=/usr/lib/jvm/default-java jdkhome=$JAVA_HOME
The full script is here:
| #!/bin/sh | |
| # | |
| # resolve symlinks | |
| # | |
| #### DV: START BUGFIX #### | |
| export JAVA_HOME=/usr/lib/jvm/default-java | |
| jdkhome=$JAVA_HOME | |
| #### DV: END BUGFIX #### | |
