I installed geos 3.6.2 following the tutorial here :
https://geonode.readthedocs.io/en/2.0/tutorials/admin/install/install_postgis.html
(except for the fact that I downloaded and installed v3.6.2 and not v3.3.8)
Now I'd like to remove it. What is the clean way to do this ?
Jump into the folder you ran
make installin and runsudo make uninstall. If that doesn't work, you'll have to run./configurefirst.
