Anaconda distribution of GRASS

Get a minimal anaconda installation

If you don't already have an Anaconda distribution on your machine, you will need to install one.

$ curl https://repo.continuum.io/miniconda/Miniconda2-latest-MacOSX-x86_64.sh > miniconda.sh
$ bash ./miniconda.sh -b -f -p $(pwd)/conda # You can install it wherever you like
$ export PATH=$(pwd)/conda/bin:$PATH

Build GRASS into the current environment

Install GRASS dependencies

It's probably best to build GRASS within a new environment. This will ensure that they dependencies are what they should be and won't mess with your current Python distribution.

$ conda create -n grass python=2.7
$ source activate grass

Install the dependencies. We use the noaa-orr-erd channel to get a working version of wxpython (the version in the defaults channel is buggy).

$ conda install --yes --file=requirements.txt -c noaa-orr-erd -c conda-forge

Get the GRASS source and compile

$ curl -O https://grass.osgeo.org/grass72/source/grass-7.2.2.tar.gz
$ tar xvfz grass-7.2.2.tar.gz

Apply patches for Anaconda build on Mac

The following patches are necessary to get GRASS to build with Anaconda on a Mac.

• platform.make.in.patch: Add Mac-specific compile and link options to use rpath with dynamic libraries.
• rules.make.patch: Run commands with LD_RUN_PATH instead of DYLD_LIBRARY_PATH. This is probably only necessary when dynamically loading libraries using load_library from the Python module grass.lib.ctypes_loader
• loader.py.patch: On Mac, additionally use LD_RUN_PATH for folders to check for libraries to load.

Almost certainly these patches will break things on non-Mac non-Anaconda builds.

To build GRASS, apply the patches, configure, and build.

Create an Anaconda package for GRASS

This will build an Anaconda package for GRASS.

$ conda install conda-build
$ cd recipe
$ conda build . -c noaa-orr-erd -c conda-forge

Create a Mac App for Grass

$ curl -O curl https://repo.continuum.io/miniconda/Miniconda2-latest-MacOSX-x86_64.sh
$ cp -r osx/Grass72.app /Applications/
$ bash Miniconda2-latest-MacOSX-x86_64.sh -b -f -p /Applications/Grass72.app/Contents/Resources
$ export PATH=/Applications/Grass72.app/Contents/Resources/bin:$PATH
$ conda install grass -c noaa-orr-erd -c conda-forge -c csdms-stack
$ conda clean --all

Create a dmg

$ mkdir grass-7.2.2
$ cd grass-7.2.2
$ mv /Applications/Grass72.app .
$ ln -s /Applications Applications

Open Disk Utility -> File -> New Image -> Image from folder, and point it to the grass-7.2.2 folder you just created.
