Clp-src

The package provides Low-level bindings to the [Clp] library. [Clp] build with [CoinUtils] ([CoinUtils-src]), [Osi] ([Clp-src])(Optional) support.

Clp (Coin-or linear programming) is an open-source linear programming solver. It is primarily meant to be used as a callable library, but a basic, stand-alone executable version is also available.

Usage

Just add the following to your Cargo.toml:

toml [dependencies] clp-src = "0.1"

Configuration

The following Cargo features are supported:

• default to osiclp and clpsolver feature;
• osiclp to build with Osi supported;
• clpsolver to build ClpSolver lib and crate the api for Rust. If you do not use Clp directly, you can disable this feature to reduce the build time;

The package build from the source and link statically by default. It also provide the following environment variables to allow users to link to system library customly:

• CARGO_COINUTILS_STATIC to link to CoinUtils statically;
• CARGO_COINUTILS_SYSTEM to link to CoinUtils system library;
• CARGO_OSI_STATIC to link to Osi statically if with_osi feature is enabled;
• CARGO_OSI_SYSTEM to link to Osi system library if with_osi feature is enabled;
• CARGO_CLP_STATIC to link to Clp statically;
• CARGO_CLP_SYSTEM to link to Clp system library;

Set the environment variable to 1 to enable the feature. For example, to link to system library dynamically, set CARGO_${LIB_NAME}_SYSTEM to 1; to link to system library statically, set both CARGO_${LIB_NAME}_SYSTEM and CARGO_${LIB_NAME}_STATIC to 1.

Windows and vcpkg

On Windows, if ${LIB_NAME}_SYSTEM is set to 1, clp-src will use [vcpkg] to find Clp. Before building, you must have the correct Clp installed for your target triplet and kind of linking. For instance, to link dynamically for the x86_64-pc-windows-msvc toolchain, install clp for the x64-windows triplet:

sh vcpkg install clp --triplet x64-windows

To link Clp statically, install clp for the x64-windows-static-md triplet:

sh vcpkg install clp --triplet x64-windows-static-md

To link Clp and C Runtime (CRT) statically, install clp for the x64-windows-static triplet:

sh vcpkg install clp --triplet x64-windows-static

and build with +crt-static option

RUSTFLAGS='-C target-feature=+crt-static' cargo build --target x86_64-pc-windows-msvc

Please see the "Static and dynamic C runtimes" in The Rust reference for detail.

Cross Compilation

you can compile it for the other target by providing the --target option to cargo build.
