My Ubuntu machine has latest GDAL (2.2.1, released 2017/06/23). But R complains that I have gdalversion <2.0
configure: CC: gcc -std=gnu99 configure: CXX: g++ checking for gdal-config... /usr/bin/gdal-config checking gdal-config usability... yes configure: GDAL: 1.11.3 checking GDAL version >= 2.0.0... no configure: error: sf is not compatible with GDAL versions below 2.0.0
How can i direct R to access GDAL (2.2.1 version) already installed on Ubuntu?
You may need to uninstall all traces of gdal then re-install it from the ubuntugis-unstable source. The following helped me solve a similar problem:
sudo apt remove libgdal-dev
sudo apt remove libproj-dev
sudo apt remove gdal-bin
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
Make sure a version >= 2.0 appears when you execute this line
sudo apt-cache policy libgdal-dev
If so, run
sudo apt update
sudo apt install libgdal-dev
I could then successfully execute in R 3.4.2 in Ubuntu 14.04 ("Trusty Tahr"):
install.packages('rgdal')
