Hi guys,

One of the issues around SWIG I'm aware of is that the .NET compact
framework doesn't support HandleRef-s that the current implementation
extensively uses.
Therefore we shall have to reimplement the default csbody and related
typemaps for using IntPtr-s along with GC.KeepAlive() or SafeHandle to
achieve similar results.
Due to the problems related to the memory ownership and the early
garbage collection I had to do such things in the current interface so
this part of the problems can be managed easily I think.

The other fundamental problem is that how the interface would fit into
the current build process. The C part of the interface might have to
be compiled along with the other parts of the GDAL/OGR project. It
would be somewhat easier to support a makefile based build process
from this aspect.

I recall that in the recent days I've chat someone who promised to
send me a working makefile and a related test project that should be
made to work...


Best regards,

Tamas
