@MartinK: thanks for the reports. It looks to be caused by a mix of libs - some provided by OSM Scout Server and some by the system. Looks like I can strip libz from provided list (included in https://github.com/sailfishos/sdk-ha...libraries.conf), but there are still few libs required for Mapnik that are not listed there (libtiff, libjpeg?). Maybe I should cleanup a list of provided libs since we are not in Harbour anyway. Let me think about it.

As for 3.0.3 issues - there is no support for it at OBS. As a result, I cannot even provide you with RPMs for that version. So, if you wish to use OSM Scout Server and MapboxGL-based widget, all I can suggest right now is to stay away from 3.0.3.x
