Ok, I got it and I'm now able to compile and end up with ZunePaint and ZuneView in their own folders.
What I'm doing now, is that I compile them into AROS hosted folder structure, so that I can test the programs directly.
Linux hosted 64bit build is under progress.
I believe that this should be part of the distributed files, native AROS is not required, executable are the sames, but to test under the environment it seems much more straight forward to have the hosted environment available.
