Spatialite in Cygwin

Using the latest setup-x86_64_2.919 to install Cygwin, I just noticed that Spatialite is not there. So, I installed it from the source code (libspatialite-5.0.1.tar.gz) and I re-installed gdal-3.5.1 from the setup file. It seems that gdal has not been compiled with Spatialite. Interestingly, the same happens although I installed gdal-3.5.1 from the source code. I just want to use the magic -sql sqlite call with the ogr2ogr command, so if anyone knows how to deal with Spatialite in Cygwin I would appreciate suggestions.

Any hints are welcomed.

Solution

  • The current Cygwin package of gdal is NOT compiled with SpatiaLite but it is compiled with indirect SQLite dependecy

     $ cygcheck gdalinfo
 ...
    D:\cygwin64\bin\cyggeotiff-5.dll
      D:\cygwin64\bin\cygproj-25.dll
        D:\cygwin64\bin\cygsqlite3-0.dll
 ...

    If you are interested to add SpatiaLite to Cygwin the best way is to offer yourself as maintainer
    See some general information on
    https://cygwin.com/packaging-contributors-guide.html

    If you are interested, you should follow the Cygwin package maintainer mailing list
    https://cygwin.com/mailman/listinfo/cygwin-apps/

    After that, adding SpatiaLite dependency to Gdal is a minor issue that will be handled by the gdal package maintainer
