jaeezzy,

I think you have dived in at the deep end with wanting to setup and configure c++ directly on the device.
I would recommend getting some experience with native linux development using a desktop before you transfer your superpowers to the tablet.
The gnu development process is covered in many places online and is used by thousands of people worldwide.
Take the time to readup and practice using gcc and make etc in a general sense

If you do not have a linux desktop I would recommend finding out about the maemo vmware image, this has a preconfigured development environment and might be a little easier to understand.

Unfortunately, there is no shortcut to becoming a linux-dev-guru, I've been trying for months now and haven't progressed that far.
