ERROR: could not open extension control file \"/usr/share/postgresql/9.1/extension/postgis.control\": No such file or directory

Is what I get when I tr

Answer 1

I had my worst nightmare while installing Postgis 2.X on SLES 12 SP1. which doesnt have compatible package in zypper repo

Here is how is resolved it on my Postgres server instance running 9.4.X

Prerequsite packages which i have installed prior to PostGis based on the errors

Proj 4 Download source cold, Build --> make install
install Gdal andjibson by adding zypper repo zypper addrepo http://download.opensuse.org/repositories/Application:Geo/SLE_12_SP1_Backports/Application:Geo.repo
zypper install gdal gdal-devel libjson-c-devel libjson

Installing Postgis

Download postgis source code (http://download.osgeo.org/postgis/source/postgis-2.3.0rc1.tar.gz)

Go to Postgis folder 
./configure --with-pgconfig=/usr/lib/postgresql94/bin/pg_config --with-geosconfig=/usr/local/bin/geos-config 
make 
make install

now if you goto postgress DB and create extension postgis; it will work

Important while configuring you should specify pg-config path and geosconfig path and You SHOULD NOT include "without Raster" as RASTER plays main role in creating the postgis extension
