[gdal-dev] mbtiles open failed

[weskerjiang at sina.cn]

i download the gdal from osgeo4w,and i write a demo to open mbtiles file,my code is below


QString uri = "c:/test.mbtiles";

CPLErrorRest();

GDALDatasetH hDS = GDALOpen(uri.toUtf8().constData(),GA_ReadOnly);

if(!hDS)

{

    .......

}


the CPLGetLastErrorMsg() shows the error     "C:/test.mbtiles not recognized as a supported file format"

so what's wrong with it?  the mbtiles file is good ,i can open it in QGIS 3.0

why it saies not supported?
