If you have not yet configured PowerShell, please go back and read the section on configuring PowerShell.
Once you have successfully configured PowerShell, you are ready to build it. This is the easiest step of all - just a simple command:
make
This should go through each source file and compile it. You will see output from gcc (the C compiler) at this point. There should not be any problems at this point - if there are, please let me know.
