[mapserver-users] MapServer and Geopackage failing

Hi Seth,

I was also testing with that same test dataset when you wrote this last 
message.  In my testing using MS4W v3.2.5 here (MapServer 7.0.7, GDAL 
2.2.3) I can display both the v1.2 and v1.0/1.1 test datasets of GPKG. 
(I remember painfully spending a lot of time building spatialite with 
sqlite, for the MS4W community).
