[Gdal-dev] Using GEOS in OGR C#

[Tamas Szekeres]

Jean,

I've tested the trunk with the GEOS option and seems to be working for
me. I've added a new example (OGRGEOS.cs) to the trunk for testing the
geos support.

I continue to think you are using an incorrect version of the
gdal14.dll. Would you mind copying the compiled version of this dll
into you application directory? You might also run the ogrgeos.exe in
the swig/csharp directory (after copying gdal14.dll here).

Best regards,

Tamas
