[postgis-users] Possible issue with Geos on PostgreSQL8.0Nati veWindows

[Obe, Regina DND\MIS]

I still have RC4 installed.  As a quick test, I replaced my postgis,
libgeos, and libproj dlls with the ones from
http://www.webbased.co.uk/mca/ .

That seemed to fix the connection disconnect problem.
Now I get for -
select geosnoop('POLYGON((0 0, 1 1,0 0))');

ERROR:  Couldnt convert the postgis geometry to GEOS!

NOTICE:  IllegalArgumentException: Number of points must be 0 or >3

For my original problematic query
select geomunion(the_geom) from neighborhoods;

I get:
ERROR:  GEOS union() threw an error!

NOTICE:  IllegalArgumentException: This method does not support
GeometryCollection arguments


So its better, but why does it seem less informative than the cygwin one
which gives me
select geomunion(the_geom) from neighborhoods;
----------------------------------------------------------------
ERROR:  GEOS union() threw an error!

NOTICE:  TopologyException: side location conflict (780343,2.95405e+06) 

Or is that related to my other problem that when I do 
select geomunion(the_geom) from neighborhoods where name IN('Dorchester',
'Charlestown');

In the Native Windows version I get
SRID=-1;MULTIPOLYGON(((778278.699002388 ...


As opposed to the cygwin which gives me more of what I expect
SRID=102686;MULTIPOLYGON(((778278.699002388  ,,,,,

Hi guys,

OK, I just downloaded and installed PostgreSQL 8.0 RC5 but didn't install
the version of PostGIS that came with it - instead I used the latest
installer from http://www.webbased.co.uk/mca/ (PostGIS 0.9.0-ish, GEOS
2.0.1, PROJ 4.4.8):


dcmms=# select geosnoop('POLYGON((0 0, 1 1, 0 0))');
NOTICE:  IllegalArgumentException: Number of points must be 0 or >3
ERROR:  Couldnt convert the postgis geometry to GEOS!
dcmms=#

So looks ok here.... Perhaps I missed some detail in the compilation
somewhere? Can anyone else recreate this?


Kind regards,

Mark.
