Missing mapelem.fdf and mapfeat.fdf in V8i Map

I try to recompile an MDL Geographics application in V8i Map and some .fdf does not exist any more.

For example mapelem.fdf, mapfeat.fdf and so on.

But some function like mdlMap_firstElementFeature, mdlMapFeature_indexFromName exists in geolib.dlo.

The question is, can I recompile declaring those function like external or the function are not available any more?

 

Thank's in advance, Ottavio.
