+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>
 Here is the shell script for building the cross compiler chain. Handmade
