-=== Compile and Run ===+From a bare ubuntu 12.04 LTS you need to add the following packages:Ìý
 +Ìý
 +<​code>​Ìý
 +sudo apt-get install build-essential m4 texinfo libncurses5-dev bzip2Ìý
 +</​code>​Ìý
 +Ìý
 +Ìý
 +Copy the script "​build_mips.sh"​ from below to your home directory. Open a terminal window in ubuntu by starting dash and typing terminal. Ìý
 +The click terminal which opens the terminal. To change the current directory to your home directory typeÌý
 +Ìý
 +<​code>​Ìý
 +cdÌý
 +</​code>​Ìý
 +Ìý
 +To see the full path of the current directory:​Ìý
 +Ìý
 +<​code>​Ìý
 +pwdÌý
 +</​code>​Ìý
 +Ìý
 +List the directory contents with Ìý
 +Ìý
 +<​code>​Ìý
 +ls -laÌý
 +</​code>​Ìý
 +Ìý
 +Change the file attributes of "​build_mips.sh"​ to executable withÌý
 +Ìý
 +<​code>​Ìý
 +chmod a+x build_mips.shÌý
 +</​code>​Ìý
 +Ìý
 +Look into the bash script with Ìý
 +Ìý
 +<​code>​Ìý
 +less build_mips.shÌý
 +</​code>​Ìý
 +Ìý
 +Extend the search path by appending "​export PATH=$HOME/​site/​bin:​$PATH"​ to your .profile fileÌý
 +Ìý
 +Log out and login again to make the PATH variable active. Check your PATH variable withÌý
 +Ìý
 +<​code>​Ìý
 +echo $PATHÌý
 +</​code>​Ìý
 +Ìý
 +You should see the <​..>/​site/​bin as the first entry. Ìý
 +Ìý
 +Run the build script withÌý
 +Ìý
 +<​code>​Ìý
 +./​build_mips.shÌý
 +</​code>​Ìý
 +Ìý
 +Ìý
 +Here is the shell script for building the cross compiler chain. HandmadeÌý
 +stuff so you need to adapt. The script will build to a place in your homeÌý
 +directory. So first add this place to your PATH variable. Ìý
