Hello! Thanks for reporting this.
The root cause of the problem is, that one .c file is autogenerated by a script during the build process. This file is not cleaned during the dh_clean phase. My suggestion would be to add this file to debian/clean. This fixes the problem for me. $ cat debian/clean src/app_version.c This needs to be done my the maintainer (Thorsten) as I have no access to the files under 'debian' sub-directory. Kind regards - Andre
