I have created a linear programming model in Python and want to solve this with the CPLEX solver on MacOS High Sierra. If I keep the problem small, the solver works just fine, if I increase the siz. It is tested with Clang 9 on Mac and GCC 8 on Linux. It has not been tested on Windows. BCP calls SCIP for branch-and-bound and calls CPLEX for solving the linear relaxation. Source code to SCIP is available free (as in beer) strictly for academic use. BCP is tested with SCIP 6.0.2.
CPLEX: Tried aggregator 1 time. CPLEX: MIP Presolve eliminated 0 rows and 1 columns. CPLEX: MIP Presolve modified 36 coefficients. CPLEX: Reduced MIP has 362 rows, 360 columns, and 1638 nonzeros. CPLEX: Reduced MIP has 342 binaries, 0 generals, 0 SOSs, and 0 indicators. CPLEX: Presolve time = 0.02 sec. CPLEX: Clique table members: 191.
Introduction
This guide explains how to install OR-Tools from source, with support for C++, 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)
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:
You should see:
C++ tools
To install C++ 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 toyota way to lean leadership ebook torrent. 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 v7.8 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.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:
Cplex For Mac Os
- 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
