[postgis-users] Intersects(geometry,geometry) fails

[Paul Ramsey]

David,
We have been unable to replicate your problem, either with compiling or 
with the function itself. I am suspicious of your hybrid compilation 
environment -- I wonder if you are getting one setup from configure and 
then compiling under another. Remember, postgis inherits its 
configuration options from the underlying postgreql configuration. So it 
will use whatever options the postgresql configure script has determined 
are optimal. Also note that gcc 3.x is required for GEOS things. So... 
make sure you are not getting cached values in your configuration, start 
from fresh source, use *only* gcc 3.x, and cross your fingers.
Magic,
Paul
