Hi Tamas,<br>
<br>
thanks a lot for Your reply.<br>
<br>
Using Your SDK I was able to track down the compilation problem - swig
did not re-generate all files<br>
and I needed to include an extra GEOS-header directory as follows:<br>
<br>
GEOS_CFLAGS = -I$(GEOS_DIR)/capi -I$(GEOS_DIR)/source/headers
-I$(GEOS_DIR)/source/headers/geos -DHAVE_GEOS<br>
<br>
-- <br>
Kind regards,<br>
<br>
Christoph<br>

<br>
You might wan't to make a test with the packages available at:<br>
<a moz-do-not-send="true" href="http://vbkto.dyndns.org/sdk/">http://vbkto.dyndns.org/sdk/</a><br>
<br>
All of those gave geos support compiled in.<br>
<br>
By downloading the SDK pacakges your could also compile gdal by
yourself easily using a VS Command Prompt and type 'nmake gdal' in the
SDK root directory.<br>
<br>
Best regards,<br>
<br>

<br>
I would like to build and use OGR with GEOS support on Windows XP 32 bit<br>
using<br>
Visual Basic.NET (.NET framework 2.0 or 3.5).<br>
<br>
GDAL/OGR 1.7.1 and GEOS 2.3.0 compilation seem to work fine (using<br>
nmake, Visual Studio 2008, only<br>
warnings, no error messages).<br>
<br>
I used the following GDAL/OGR nmake.opt settings to include GEOMS
support:<br>
<br>
# Uncomment for GEOS support<br>
GEOS_DIR=D:\svn\code\Tools\geos-3.2.0<br>
GEOS_CFLAGS = -I$(GEOS_DIR)/capi -I$(GEOS_DIR)/source/headers
-DHAVE_GEOS<br>
GEOS_LIB = $(GEOS_DIR)/build/msvc90/Release/geos_c_i.lib<br>
<br>
But using GEOMS in a sample .NET project always results in an exception<br>
"GEOS support not enabled".<br>
<br>
Sample code:<br>
<br>
Ogr.RegisterAll()<br>
<br>
Dim g1 As Geometry = Geometry.CreateFromWkt("POLYGON((0 0,<br>
10 10, 10 0, 0 0))")<br>
Dim g2 As Geometry = Geometry.CreateFromWkt("POLYGON((-90<br>
-90, -90 90, 190 -90, -90 -90))")<br>
<br>
Dim result As Boolean = g2.Contains(g1)<br>
<br>
I copied all GDAL/OGR wrapper libraries and geos_c.dll to the<br>
appropriate places.<br>
<br>
Any suggestions?<br>
<br>
Thanks a lot...<br>
<br>
Christoph<br>
