 +From a bare ubuntu 12.04 LTS you need to add the following packages:
 +
 +<code>
 +sudo apt-get install build-essential m4 texinfo libncurses5-dev bzip2
 +</code>
 +
 +
 +Copy the script "build_mips.sh" from below to your home directory. Open a terminal window in ubuntu by starting dash and typing terminal. 
 +The click terminal which opens the terminal. To change the current directory to your home directory type
 +
 +<code>
 +cd
 +</code>
 +
 +To see the full path of the current directory:
 +
 +<code>
 +pwd
 +</code>
 +
 +List the directory contents with 
 +
 +<code>
 +ls -la
 +</code>
 +
 +Change the file attributes of "build_mips.sh" to executable with
 +
 +<code>
 +chmod a+x build_mips.sh
 +</code>
 +
 +Look into the bash script with 
 +
 +<code>
 +less build_mips.sh
 +</code>
 +
 +Extend the search path by appending "export PATH=$HOME/site/bin:$PATH" to your .profile file
 +
 +Log out and login again to make the PATH variable active. Check your PATH variable with
 +
 +<code>
 +echo $PATH
 +</code>
 +
 +You should see the <..>/site/bin as the first entry. 
 +
 +Run the build script with
 +
 +<code>
 +./build_mips.sh
 +</code>
