Just did a quick test and it seems that the "generate makefile" and "ceate new project" options aren't working with MorphED and the current SDK

I really hope Dietmar updates Cubic to the new IDE sometime soon....

In the meantime you might take one of the simplier Examples, copy it somewhere else, adapt the provided makefile and replace the *.c file with your own code.

Not very elegant, but learning makefiles is never a bad idea anyways.
