- | === Compile and Run === | + | 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 | ||
+ | stuff so you need to adapt. The script will build to a place in your home | ||
+ | directory. So first add this place to your PATH variable. | ||
+ | |||
+ | <code bash build_mips.sh> | ||
+ | #!/bin/bash -ev | ||
+ | # -e => exit on error | ||
+ | # -v => verbose output | ||
