[postgis-users] error in using Contains command

[david techer]

Hi

fisrt all do

select postgis_full_version()

to see if postgis was compiled using proj and geos

I think U installed proj and geos using classical commands:

./configure && make && make install

so try for postgis

Use ./configure --with-proj=/usr/local 
--with-geos=/usr/local/bin/geos-config

> proj-libs=/usr/local/lib/ --with-geos-libs=/usr/local/lib/",make ,make 
> install" and
> I got no error.
