# Building gcc from source isn't necessarily an easy task, and it requires
# a lot of various dependency packages to work properly. The easiest way
# to use a mips compiler for Linux is still to use a package from your
# distribution. Nevertheless, here's how to build a working mips compiler
# that can produce code for the R3000A CPU, granted you have the necessary
# dependencies to do so. The script can be run as root, or as a regular user
# when the PREFIX environment variable is provided.
