Andreas, > I am struggling with libspatialite. What libspatialite versions are you > guys using?

I tried both with proj-6.3.2 and > proj-7.0.1. libspatialite-4.3.0a isn't happy with either proj version.
For 4.3.0a: CFLAGS="-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H -O2 should help: https://github.com/OSGeo/gdal/blob/master/gdal/docker/alpine-normal/Dockerfile#L248 You can also build against the development repository of Spatialite: https://github.com/OSGeo/gdal/blob/master/gdal/ci/travis/ubuntu_1804/install.sh#L27 (you could probably drop the "fossil update 90180e065d" which must have been a workaround against a regression, and the other peculiarities), so mostly: fossil clone https://www.gaia-gis.it/fossil/libspatialite libspatialite.fossil mkdir sl cd sl fossil open ../libspatialite.fossil ./configure [...] > I noticed that there > hadn't been a lot of activity with this library in the past months/years. Yes, I've tried to maintain a communication channel with the developper, but with moderate success only. The development is not abandoned, but only at a rather slow pace. > On a related question: could I build QGIS without libspatialite? I > failed to do so, but maybe there are some tricks. I don't think you can without some surgery in the code base. FWIW, the WFS provider depends on it for caching (could potentially be replaced by something else) Even -- Spatialys - Geospatial professional services http://www.spatialys.com
