[postgis-users] polygonize requirements

[Markus Schaber]

Hello,

According to the PostGIS manual, polygonize works with "GEOS >= 2.1.0".
However, I get the following error message:


logigis=# select polygonize('LINESTRING(1 1, 1 0, 0 0, 0 1, 1 1)');
NOTICE:  GEOS library does not support required interface 3
 polygonize
------------

(1 row)

logigis=# select postgis_full_version();
                                         postgis_full_version

------------------------------------------------------------------------------------------------------
 POSTGIS="1.0.0" GEOS="2.1.1" PROJ="Rel. 4.4.9, 29 Oct 2004" USE_STATS
DBPROC="0.3.0" RELPROC="0.3.0"
(1 row)



It is a PostGIS debian package that was compiled by one of our admins
for an AMD-64 Ubuntu machine.
