how to move from keil to linux?

Well, that's a 3rd-party site - nothing to do with Keil ot ARM.

If you want support with that, you will have to contact the author.

But the examples from Nordic should give you enough to understand what to do ...

That site is rather out-of-date now (using SDK 14)

okay thanks for the help

I am trying to make the Makefile by own using that .uvprojx file.

Start with one of the known-working makefiles from Nordic.

Then you just need to add any extras specific to this code.
