GDAL 2 On Mac with Homebrew

Originally published on my personal blog.

This is a small post about upgrading to gdal 2.x on a Mac using homebrew.

Assumptions

• You have homebrew installed and setup.
• You already have gdal 1.x installed via homebrew's default 'gdal' formula.

Install gdal 2.x

• Unlink gdal 1.x using
  brew unlink gdal
  

• Tap into osgeo4mac
  brew tap osgeo/osgeo4mac && brew tap --repair
  

• Install gdal2.
  
  

brew install gdal2 --with-armadillo \ --with-complete --with-libkml --with-unsupported 

• Link gdal2
  brew link --force gdal2

• Verify
  

 $> gdal-config --version 2.1.1 $> gdal-config --libs -L/usr/local/Cellar/gdal2/2.1.1/lib -lgdal $> gdal-config --cflags -I/usr/local/Cellar/gdal2/2.1.1/include 

Post Install

If you are using R for geo-spatial stuff, be sure to reinstall the rgdal library. Also you can now install sf in R using devtools::install_github('edzer/sfr').
