On windows, everything works great - I use these commands to open a globe with a map:
marbleWidget->setMapThemeId("earth/openstreetmap/openstreetmap.dgml");
and a globe is opened with a details on it (I can zoom in and out)

but on linux, the same command but only a light blue circle is opened with no details.
why is this happening? how can I fix it?

thank you so much for all your help here. trully amazing project.

Is there is any console output from Marble which may indicate why it is failing to load the globe?

No output that concerns marble ( just warning of my own code).
I should mention that I copied the 'data' directory ( that contains the 'map' directory) to the executble directiry, since I thought that marble is assuming that 'data' directory is there.
If I try to use a different maps:
setMapThemeId("earth/citylights/citylights.dgml");
setMapThemeId("earth/plain/plain.dgml");
setMapThemeId("earth/precip-dec/precip-dec.dgml");


and a globe opened with details very nicely. But when I zoomed in – the details didn’t get any more specific. (I guess he map is just a picture and doesn’t connect to the internet line openstreetmap)
so only openstreetmap doesn’t work.
(I want to remind that in windows, openstreetmap map does work)

maybe its a proxy problem? I couldt find any documentation on this issue in your documentation.

Very odd - it shouldn't be necessary to set a proxy - unless your network requires one of course.
I'll leave it to the Marble developers to comment on why the OpenStreetMap one does not work.

This sounds like your proxy settings are not correct.

sorry, you are right. thank you.
