Introduction
This guide explains how to install OR-Tools from source, with support for Java, on MacOS. Unless you plan to modify the source code or use a third-party solver with OR-Tools, we recommend the binary installation.
Although these instructions might also work on other MacOS variants, we have only tested them on machines meeting the following requirements:
- MacOS 10.15.5 (Catalina) 64-bit (x86_64)
Project: jdk8u-jdk File: MacKAT.java Source Code and License. @Override public void run(Provider p) throws Exception Mac mac = Mac.getInstance(alg, p); SecretKey keySpec = new SecretKeySpec(key, alg); mac.init(keySpec); mac.update(input); byte macv = mac. This page provides Java code examples for javax.crypto.Mac.getInstance. The examples are extracted from open source Java projects. Java in Visual Studio Code also supports source code navigation features such as search for symbol, Peek Definition, and Go to Definition. The Spring Boot Tools extension provides enhanced navigation and code completion support for Spring Boot projects. One of the key advantages of VS Code is speed.
Notepad Notepadis a popular free to use code editor written in C. It uses pure win32 API.
Note: OR-Tools only supports the x86-64 (also known as amd64) architecture.Prerequisites
The following sections describe the prerequisites for installing OR-Tools from source.
Xcode Command Line Tools
You must install the Xcode Command Line Tools. To do so, open the Terminal, found in /Applications/Utilities/
, and enter:
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:
You should see:
Homebrew
To install the remaining prerequisites, we recommend first installing the 'missing package manager for macOS' otherwise known as Homebrew. To do so, open a terminal window and enter:
To verify that you’ve successfully installed brew:

C++ tools
To install C++ tools, open a terminal window and enter:
SWIG tool
To install SWIG tool, open a terminal window and enter:
Java tools
To install Java tools, open a terminal window and enter:
Download the source code
There are two distinct branches of the OR-Tools source code onGitHub: stable and master.The stable branch has been thoroughly tested and should work flawlessly on allsupported platforms. The master branch is where the latest updates and improvementshave been applied; it's more current, but less stable.
Download the stable source code
You can get the stable source code for OR-Tools in either of the following ways:
- Clone the stable branch by entering
- Download the latest release in a compressed file, byclicking the Clone or download buttonin GitHub.
Download the master source code
To retrieve the source code from the master branch, enter
Download previous releases
You can get the source code for previous releases in either of the following ways:
- Download a previous release from the GitHub release page.
- Assuming you have already created a local repository (by
git clone
), you can check out a specific release using a Git tag. For example, to work with the v8.0 release instead of the master branch, enter the following commands in your local repo:
Build third parties
Before building OR-Tools, you'll need to build the required third party software.
Open a terminal and navigate to the directory where you extracted the files. Then enter:
Using SCIP
Since v7.8, SCIP is now integrated so you won't have to install it manually.
Warning:While OR-Tools ships with SCIP, please consult theSCIP license to ensure that you are complying with it.Java Programming On Mac
Using Gurobi
Gurobi is now pre-integrated. When needed, at runtime, OR-Tools will search for the Gurobi shared library in the default install path of the Gurobi installers on MAC OS X and Windows, or by using the GUROBI_HOME
environment variable.
Using an optional third-party solver
You can also use OR-Tools with any of the following optional third-party solvers whose support is disabled by default:
- GLPK(Linux and MacOS only)
To configure OR-Tools to use one of these solvers, do the following steps:
- Install the optional solver following the vendor instruction.
- Open
Makefile.local
and add the path to the directory where you have installed the solver. For example, for CPLEX you would add this:
Build the source code
To build the source code, open a terminal and navigate to the directory where you extracted the files. Then enter the following command to compile OR-Tools:
Test the source code
You can check that everything is running correctly by entering:
This runs a selection of examples for OR-Tools. If all the examples run successfully, you are ready to get started with OR-Tools.
Cleaning the build files
If you need to re-install OR-Tools, the command:
will remove all compiled dependencies and Makefile.local
. This can be useful for resetting to a clean state.
Then re-enter the commands
Note: This code is currently a work in progress. I try to demonstrate some possible approaches, but I don’t know of a perfect working solution yet.
I’m currently trying to find the right way to find the current monitor size, when you’re writing a Java Swing application to work in a multiple-monitor configuration. I always use three monitors, so I can test this pretty easily.
Java default screen device

This SO post says that this code works, but it doesn’t work for me on Mac OS X 10.10:
From what I can tell, the “default” screen device is not the same as the “current” screen device. For instance, my default screen device seems to be my display that’s in the middle of the three that I use, but that’s not the same as what I consider to be the “current” display, which to my way of thinking is the display where my JFrame
is currently displayed.

This second approach, which is based on an answer that’s shown lower on that page, does give me three different monitor sizes, so I hope the answer is in there somewhere:
With two monitors connected to my MacBook, with the MacBook lid closed, I see this output from this method:
If you’re trying to work with multiple monitors in a Java Swing or JavaFX application, I can’t tell you exactly how to determine the current monitor size, but as I mentioned, that last code does give different monitor sizes.
One-monitor screen resolution solution
FWIW, those approaches should work if you have only one monitor/display. This older approach should also work:

Also, here’s the source code for a complete Java application you can use to test the problem, and possibly find a solution:

Finally, I guess I should say that the first approach may work on MS Windows, I don’t know, but as I mentioned, I can confirm that it doesn’t work on Mac OS X.
