Repeated rosmake failure

edit

I'm trying to install ardrone_autonomy and tum_ardrone, both of which I have downloaded. However, whenever I use rosmake with these packages I get the error

SyntaxError: EOL while scanning string literal

It's consistently the same error for both packages. Any ideas as to what is causing this?
