[postgis-users] intersects:: operation not implemented

[Maik Trömel]

Hello PostGIS-Users,

I wanted to run an intersection and I got the following error:
   
    ERROR:  intersects:: operation not implemented - compile PostGIS 
with JTS or GEOS support

I don't know what I've done wrong during installation. But thats not the 
point.
Is it possible to implement the things that are missing after the 
installation? And how can I do this?

Thanks for your help

Greetings Maik
