Hi; I am trying to build and install the GDAL library on Windows XP using the following commands:
nmake /f makefile.vc nmake /f makefile.vc install nmake /f makefile.vc devinstall In order to build with GEOS support, I uncommented the lines in the "nmake.opt" as follows: GEOS_DIR=C:\geos-3.1.1 GEOS_CFLAGS = -I$(GEOS_DIR)/capi -I$(GEOS_DIR)/source/headers -DHAVE_GEOS GEOS_LIB = $(GEOS_DIR)/source/geos_c_i.lib However, I still get the same .dll and .lib files as if no GEOS support was turned on (the sizes are exactly the same). When I try to call "OGRGeometry::Contains()" method, I also get the error: "ERROR 6: GEOS support not enabled." What could be wrong? 2) I was also wondering whether OGR library provides a kind of nearest neighbour finding facilities? If not, does anybody know any library that could be integrated with OGR for this purpose? I plan to use it to find the n nearest sounding points (SOUNDG) given a point, to make a prediction about its depth. 3) Finally, is there any facility in OGR for querying a layer such that it will only return the features on it, which contain a given point as parameter? Because I could not come up with an SQL statement to perform this task. Actually I was planning to use this on the DEPARE (depth area) layer on an S-57 file to find the depth area polygon that covers the given point. Any idea or references about these issues would greatly be appreciated.
