This is a pretty straightforward error. Either you have a file called "sample" 
already existing with permissions that do not allow your current user to 
overwrite it, or the directory itself does not have permissions set allowing 
you to write files to it. Either way, you probably shouldn't be doing your 
work with the standard SDK in the SDK installation path - create a new 
directory somewhere more appropriate (e.g. under your home directory) for your 
source code and build your files there.

Cheers,
Paul
