Introduction
This guide explains how to install OR-Tools for C++ on MacOS.
Although these instructions might also work on other MacOS variants, we
have only tested them on machines meeting the following requirements:
MacOS 13.0.1 (Ventura) Intel 64-bit (x86_64)
MacOS 13.0.1 (Ventura) M1 (arm64)
Prerequisites
The following sections describe the prerequisites for installing OR-Tools.
Xcode Command Line Tools
You must install the Xcode Command Line Tools. To do so, open the
Terminal, found in /Applications/Utilities/, and enter:
xcode-select--install
Click “Install” to download and install Xcode Command Line Tools. You don’t need
to "Get Xcode" from the App Store. If you have a slow Internet connection, it
may take many minutes.
Verify that you’ve successfully installed Xcode Command Line Tools:
xcode-select-p
You should see:
/Library/Developer/CommandLineTools
Installing OR-Tools
Take the following steps to install the OR-Tools library for C++:
Download and extract the binary distribution for your system:
To test your C++ installations, open a terminal window and navigate to
the directory where you unpacked the binary distribution. Then enter the
following command:
maketest
This runs a selection of examples for OR-Tools. If all the examples run
successfully, you are ready to
get started with OR-Tools.
