Google Or-Tools

or-tools is a Rust library that binds to certain specific features of the Google Or-Tools C++ library.

This repository will dedicate itself to improve the library's content.

These include:

• TBD # TODO: to be implemented!

Building

Minimum Rust Version

Please udjust your Rust compiler to version 1.73 or higher.

Supported Platforms

• Linux { aarch64, x86_64 }
  • Alpine Edge
  • Arch Linux (AUR)
  • CentOS 7 LTS
  • Debian 11
  • Fedora 37, 38

Your package manager may not support deployment on platforms marked as Supported above.

For better maintenance, please let us know whether the other platforms support it. Besides, you may claim us whether the specific platform should support it through Issues .

Dependencies

• C++20 Compiler (GCC 10 or above)
• cmake >= 3.18
• [optional] Or-Tools C++

Building Dependencies

• git

Building Native library

or-tools requires Or-Tools to be installed. You can either provide a existing system-wide installation, or build it with this library.

• To build it in compile-time if there is no system library:

  • cargo build

• To forcely use a system-wide dependency:

  • cargo build --no-default-features

• To forcely build it in compile-time:

  • cargo build --features build-native-force

The C++ library Or-Tools will be installed via or-tools-sys when the build-native feature flag is enabled.

For the build, this library uses cmake, so please make sure to have cmake .

The build-native flag is enabled by default, supporting build speed and convenience at the same time.

The build-native-force flag overrides native libraries installed on the system. It is disabled by default, offering increased build times.

Building Rust package

or-tools includes a solver-all feature flag enabled by default.

solver-all will enable all kinds of supported open-source solvers. The latest information about the solvers can be found here: https://github.com/google/or-tools/blob/stable/cmake/README.md#solvers-supported

The solver-all flag can be disabled with cargo build --no-default-features.

GPL/Proprietary Solvers

or-tools includes a solver-all-nonfree feature flag that can be used with cargo build --features solver-all-nonfree .

solver-all will enable all kinds of supported solvers including GPL and/or proprietary ones. The latest information about the solvers can be found here: https://github.com/google/or-tools/blob/stable/cmake/README.md#solvers-supported

For detailed instructions on embedding proprietary solvers, please follow to the link below:

• CPLEX: https://github.com/google/or-tools/blob/stable/cmake/README.md#enabling-cplex-support
• XPRESS: https://github.com/google/or-tools/blob/stable/cmake/README.md#enabling-xpress-support

The solver-all-nonfree flag is disabled by default, offering increased build times.
