[mapserver-users] MapServer and Geopackage failing

Hi all,

I'm trying out the geopackage format as an alternative to shapefiles but running into an issue where MapServer expects the geopackage dataset to include spatialite. Drawing layers with shp2img logs the following:

[Tue Mar 06 10:39:42 2018].512000 msDrawMap(): rendering using outputformat named png (AGG/PNG).
[Tue Mar 06 10:39:42 2018].512000 msDrawMap(): WMS/WFS set-up and query, 0.000s
[Tue Mar 06 10:39:42 2018].529000 msOGRFileOpen: Spatialite support in GPKG not enabled
[Tue Mar 06 10:39:42 2018].549000 msOGRFileNextShape(): OGR error. OGR GetNextFeature() error'd. Check logs.
[Tue Mar 06 10:39:42 2018].549000 msOGRFileNextShape(): In ExecuteSQL(): sqlite3_prepare(SELECT spatialite_version()):
  no such function: spatialite_version
[Tue Mar 06 10:39:42 2018].550000 msDrawMap(): Image handling error. Failed to draw layer named 'ways'.  

The spatialite_version function is missing in the geopackage. The dataset was created by exporting from MapServer as an OUTPUTOPTION:

      OUTPUTFORMAT
        NAME "GeoPackage"
        DRIVER "OGR/GPKG"
        FORMATOPTION "STORAGE=memory"
        FORMATOPTION "FORM=simple"
        FORMATOPTION "FILENAME=result.gpkg"
        FORMATOPTION "DSCO:SPATIALITE=YES"	# not a listed option, but tried anyway	
        FORMATOPTION "LCO:SPATIAL_INDEX=YES"
    END
  
Running a GisInternals build,  including GDAL 2.1.3 and MapServer 7.0.4. 

Relevant code is at https://github.com/mapserver/mapserver/blob/aae74ff2abed3f2f8fe1f76c9b4bbccf15023dc1/mapogr.cpp#L1313
It looks like the error should be swallowed up?

The same dataset exported directly to spatilite works fine. 

Anyone experienced the above issue?

Regards,

Seth
