[Gdal-dev] Coordinate transform problem

[Chapman, Martin]

Ethan and Frank,
 
Thanks very much for your help.  After some debugging I think it is the
environment I'm using rather than anything related to GDAL/GEOS...which
is kind of what I figured since both of those libraries usually compile
without problems.
 
Thanks again,
Martin

	Keep in mind if you install GEOS 2.x you'll need to upgrade to
postgis 0.9.0 or keep two versions of GEOS installed.

	Martin,
	
	GDAL requires GEOS 2.0 or newer if you want GEOS support.  The
GEOS source
	is not part of GDAL so you need to pre-build and install GEOS if
you
	want to configure GDAL with it.   I don't know if PostGIS is
using
	GEOS 2.0 yet or not. I haven't actually tried to GEOS enable my
PostGIS
	installation yet.
	
	Best regards,
