Stefan, please try the attached patch.
copy the patch in the googlemaps plugin directory and call this:
$ git apply <name.patch>
$ qmake
$ make
if it builds try building and running subsurface again:
- does it show the map? are there crashes?
- try the zoom-in / out, and panning around
- disable your internet connection for a while and see if the map
tiles are cached for offline mode
if there are errors or any warnings, please report them.
thanks
lubomir
