Introduction

| Requirement | Dependencies | Compilation | Testing | Integration | CI |

OR-Tools comes with a Bazel based build (WORKSPACE) that can be used on a wide range of platforms. If you don't have Bazel installed already, you can download it for free from https://bazel.build/.

warning: Currently OR-Tools Bazel doesn't support Python, Java nor .Net, please use the Makefile or CMake based build instead.

Requirement

You'll need:

• Bazel >= 5.4.0.
• A compiler with C++17 support.

Solvers supported

Here the list of supported solvers:

• CP-SAT
• GLOP
• GLPK
• PDLP
• SCIP

Dependencies

OR-Tools depends on several mandatory libraries.

• Eigen
• Google Abseil-cpp,
• Google Protobuf,
• Google Gtest,
• Bliss,
• SCIP,
• GLPK (GNU Linear Programming Kit)

Compilation

You must compile OR-Tools using at least C++17 (C++20 on windows):

• on UNIX:

  bazel build -c opt --cxxopt=-std=c++17 ...

• on Windows when using MSVC:

  bazel build -c opt --cxxopt="/std:c++20" ...

Testing

You may run tests using:

• on UNIX:

  bazel test -c opt --cxxopt=-std=c++17 ...

• on Windows when using MSVC:

  bazel test -c opt --cxxopt="/std:c++20" ...

Integration

To integrate OR-Tools in your own Bazel project, you can take a look at the template project: or-tools/bazel_or-tools.
