When running Scala on Ubuntu Linux,
scala myscript.scala, if the network configuration in your
/etc/hosts file does not have a loop back address you can experience the following error:
Could not connect to compilation daemon.
gksudo gedit /etc/hosts and ensure there are the following lines at the top of the file:
127.0.0.1 localhost 127.0.0.1 mycomputer
Where mycompter is the name you gave your Ubuntu computer when you installed it.
It would seem that the scala compilation daemon does not pick up the network address when running scripts. The same problem occurs when there is no network, but I have not found a workaround as yet (except to find a wireless hotspot).
