Compiling on MacOSX using homebrew
What is homebrew and why use it
To quote from their website:
- easy to install
- does not need administrator privileges
- installs packages to their own directory and then symlinks their files into /usr/local
The formulas to install programs are called recipes and they make it possible to install several version of the same program (as well as HEAD of different Version Control Systems) at the same time which can then be symlinked. This makes it perfect for the purpose of installing the master branch of GRASS GIS for testing purposes.
GRASS GIS 7.6+
brew tap osgeo/osgeo4mac
brew install osgeo-grass
Easy, isn't it?
You can also install via URL:
- by running (change '7x' to the current version)
brew test -v grass-7x
you can run GRASS GIS tests but they are not implemented as they should be - work in progress.
GRASS GIS 7.2
If you have a 3rd party Python installed, and/or Python 3, you need to remove it from your path for the installation. Once installed, GRASS will run even if the primary Python is, for example, Anaconda Python 3.
Display the current path, and remove any folders or directories that provide access to the non-system python2.7:
echo $PATH # ~/local/anaconda/bin:/Users/MyName/bin:/usr/local/bin:/usr/bin/sbin
Set GRASS python
Install packages with Brew
brew tap osgeo/osgeo4mac brew install netcdf brew install gdal2 --with-complete --with-unsupported export GDAL_DATA=/usr/local/opt/gdal2/share/gdal/ # Also add the above line to ~/.bash_profile, ~/.bashrc, or some other login script brew install grass7 --with-netcdf brew install gdal2-grass7
- PATH adjustments are only needed during installation. After installation, the PATH can return to its default value and GRASS works fine.
- There may be other brew dependencies that were installed previously and therefore not listed here.
GRASS GIS 7.0.x for El Capitan without disabling SIP
The new homebrew recipe for GRASS 7.0 does install on El Capitan with SIP enabled! This is thanks to Larry Shaffer. See https://github.com/OSGeo/homebrew-osgeo4mac/issues/118#issuecomment-200278686
The recipe is part of the Homebrew-osgeo4mac tap, see
for info on how to use them.
