Notes about Geneious on Linux
Whether or not Geneious runs in 32 bit or 64 bit on Unix is entirely dependent on the Java used to run it. We provide packages of Geneious that come with either the 32 bit or 64 bit version of Sun's Java as well as one without Java.
Geneious uses the first valid JRE that it finds when looking in the following places:
- The JRE defined by the environment variable INSTALL4J_JAVA_HOME_OVERRIDE
- A JRE located within a directory named jre inside the Geneious installation directory
- The system default JRE. Use the command "which java" to find out what this is. The command "java -version" will tell you what version of java this is.
The easiest way to run Geneious with your own version of Java is to perform the following steps:
Step 1
Open [Geneious installation Directory]/Geneious in your favorite text editor. Find the following line
# INSTALL4J_JAVA_HOME_OVERRIDE=
Step 2
Then remove the hash and change it to point to your Java installation directory.
Example: INSTALL4J_JAVA_HOME_OVERRIDE=/opt/jdk
Note that we recommend you use a Sun distribution of Java rather than an OpenJDK derivative.
