Installing OR Tools for Python on an M1 Processor Mac

Hi all,

I have been trying to install OR Tools on my Mac Big Sur 11.1 with an Apple M1 chip with no luck so far. I am using a conda environment with Python 3.9.1. What I've tried:

1. Installing using the binary distribution as instructed here: https://developers.google.com/optimization/install/python/mac

I receive the error message "No matching distribution found for ortools" which makes sense as from how it looks there is no version for this stack: https://pypi.org/project/ortools/#files

2. Installing from source as instructed here: https://developers.google.com/optimization/install/python/source_mac

My guess is maybe there are special adjustments needed to be done and a specific distribution to be released for this processor? or maybe I am missing something? Anyone had any experience with this kind of stack?

Any help would be appreciated!

Natan.

I too am having issues with installing OR Tools on an M1 Mac using Big Sur 11.2.2. Same error message for installing via Pip (using Python 3.9.2 and pip 21.0.1).

Installing from source is quitting after this error:

./ortools/base/commandlineflags.h:17:10: fatal error: 'absl/flags/declare.h' file not found

Also, the third_party make quit after a few errors for src/nlpi/exprinterpret_cppad.cpp

make third_party USE_SCIP=OFF, or make third_party -k to build absl

Thanks so much Laurent. That got me a bit further. Last set of errors on build python (note I am running MacOS 11.2.2):

Definitely getting closer.
