C under a Windows box is going to use different libraries, etc. than the linux based 770. The other thing is the 770 has an ARM based processor unlike your desktop.

I'm average with C/C++ and Linux and I'm still a far ways off from spitting anything out for the 770. I might take a stab at Python later but not for now.

Anyway, what you might want to do is get a "live" distro of Linux like Ubuntu or Knoppix (just burn them to a CD and boot off of it - you'll be in Linux without having to screw with your harddrive) and play around. I'm not sure if they have the dev packages installed but Ubuntu might.

It's a start anyway to get familiar with that side of things.

G'luck!
