Daniele,

Well then you are on the right track.

My understanding is that no special configure/build options are required
for the DXF imagemap support but I suspect it doesn't work as well in
4.0.x.  I would strongly encourage you to upgrade to 4.2.x and GDAL 1.2.1.

Because OGR does not support DXF.  The imagemap/dxf support is not
implemented using DXF or any external DXF library.  It just uses lots
of fprintf() calls to produce appropriate DXF as far as I know.

I think you will find the basic shapelib include file in
gdal/ogr/ogrsf_frmts/shape.  However, the "master" version of shapelib
no longer lives in the GDAL source tree.  I guess you would be best off
building Geo-Shapelib seperately.
