[Qgis-developer] New OpenStreetMap integration

[Denis Rouzaud]

Hi Martin,

I got this error when I compile this morning.

 1.
    /home/denis/opt/qgis/Quantum-GIS/build-master/python/core/sipcorepart3.cpp:
    In function 'PyObject*
    meth_QgsFeatureRequest_setFilterFid(PyObject*, PyObject*)':

    /home/denis/opt/qgis/Quantum-GIS/build-master/python/core/sipcorepart3.cpp:42358:47:

    /home/denis/opt/qgis/Quantum-GIS/python/../src/core/qgsfeaturerequest.h:85:24:
    note:   no known conversion for argument 1 from 'QString' to
    'QgsFeatureId {aka long long int}'

Not sure it is related to the OSM integration.

Do you have any tip?

Thanks a lot,

Denis
