[postgis-users] Postgis 2.0 installation Problem - "undefined reference to `GEOSGeom_createEmptyPolygon'"

[Alexandre Neto]

Lets see I have the enough strenght to fight it! :-D

Probably I will start by uninstall and purge GEOS, and start from the
beginning. And then other software might not work, that means I will have
to fight it too.

Thanks,

Alexandre Neto
