Hi Stefan, hi Greg, thank you very much for your reply. With your help I managed to compile a hello World example with success on a few distributions. But I have two problems: 1. The built packages are empty. I guess I have to somehow add an instruction how to build the package(define which binaries should be installed with the package)? My workspace: https://build.opensuse.org/package/view_file/home:tol_qosmotec/helloWorld/he... https://build.opensuse.org/source/home:tol_qosmotec/helloWorld/helloWorld-1.... 2. Only CentOS Builds are started at the moment. The Debian and Ubuntu builds are marked as "excluded". I haven´t figured out why yet. Do you have any idea? One last thing for my understanding: Do I have to create an archive of my sources every time? Cause on our build server we have a source folder. I think it seems a bit unnecessary to do that every time when it needs to be unpacked shortly after that in the build distribution.
