Success!! Ok for those who can be interested, these are the steps I made:
* download and compile gdal 2.2.3 (compiled in the /opt folder) * recompiled QGIS by changing the gdal paths and enable the flag WITH CUSTOMWIDGET * all went fine and QGIS is compiled against gdal 2.2.3 * in the output/lib directory there is the libqgis_customwidgets.so and libqgis_customwidgets.so.3.1.0 files * I copied this files to /usr/lib/x86_64-linux-gnu/qt5/plugins/designer/ Q3 widgets are there. I still see they are saved with widget.h in the ui, so I guess one has to change the path manually or promote the widget like Etienne suggested Cheers Matteo _______________________________________________ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
