Where is SCALA_HOME on Ubuntu?

Question

I installed Scala on Ubuntu using the following

sudo apt-get install scala   ~$ which scala /usr/bin/scala  ~$ whereis scala scala: /usr/bin/scala /usr/bin/X11/scala /usr/share/man/man1/scala.1.gz  ~$ scala -version Scala code runner version 2.9.1 -- Copyright 2002-2011, LAMP/EPFL 

My question is what should I put in the variable SCALA_HOME? /usr/bin ?

Answer 1

Today I installed scala using "apt-get install scala" and confirmed the scala jar files are located in /usr/share/java

You should be able to set your SCALA_HOME to /usr/share/java and have it all work. I assume you want to use NetBeans so you will need to set SCALA_HOME in your .profile (or .bash_profile) rather than in your .bashrc because NetBeans won't see any variables set in your .bashrc unless you start it from the command line

$ find / -maxdepth 6 -iname \*scala\*jar 2> /dev/null /usr/share/java/scala-dbc.jar /usr/share/java/scala-partest.jar /usr/share/java/scala-partest-2.9.1.jar /usr/share/java/scala-dbc-2.9.1.jar /usr/share/java/scalacheck.jar /usr/share/java/scalap.jar /usr/share/java/scala-library-2.9.1.jar /usr/share/java/scala-compiler-2.9.1.jar /usr/share/java/scala-library.jar /usr/share/java/scalacheck-2.9.1.jar /usr/share/java/scala-compiler.jar /usr/share/java/scala-swing-2.9.1.jar /usr/share/java/scalap-2.9.1.jar /usr/share/java/scala-swing.jar 

Answer 2

For me its: /usr/share/java/scala I determined this by doing dpkg -L scala

This assumes you install scala using APT.
