codegoalie / nachos-java on Ubuntu
Created October 27, 2010 18:48
These are the steps I took to get nachos-java working on UBuntu 10.10
Setting up NACHOS in Ubuntu Linux
1) Download and Extract the nachos-java.tar.gz
2) Install sun-java6-jdk package. (sudo apt-get install sun-java6-jdk)
3) Add the nachos executable to your PATH, by adding the following lines to your ~/.profile file.
if [ -d "$HOME/nachos/bin" ] ; then
PATH="$HOME/nachos/bin:$PATH"
