Bonmin-src crate is a *-src crate. This links Bonmin libraries to executable build by cargo, but does not provide Rust bindings. [Bomin] is built with CoinUtils (CoinUtils-src), Osi (Osi-src), Cgl (Cgl-src), Clp (Clp-src), Cbc ([Cbc-src]), Ipopt (Ipopt-src), Mumps (Mumps-src)(Optional), OpenBLAS (OpenBLAS-src)(Optional) and Intel-mkl (intel-mkl-src)(Optional).

By this package, you don't need to worry about installing Bonmin in the system, and it's a package for all platforms.

Bonmin (Basic Open-source Nonlinear Mixed INteger programming) is an open-source code for solving general MINLP (Mixed Integer NonLinear Programming) problems.

1. add the following to your Cargo.toml:

   [dependencies]
   bonmin-src = "\*"

2. add the following to your lib.rs:

   extern crate bonmin_src;

This package does not provide bindings. Please use coinbonmin-sys, coinipopt-sys, coincbc-sys, coinclp-sys to use Bonmin, Ipopt, Cbc, Clp, e.g.

[dependencies]
coinbonmin-sys = { version = "\*" }

Note: The C interface is taken from the master branch of Bonmin, which is still has a number of todos.

The following Cargo features are supported:

• default;
• cplex to build with cplex(Need to install cplex in the system);
• filtersqp to build with filtersqp(Need to install filtersqp in the system);

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_BONMIN_STATIC to link to Bonmin statically;
• CARGO_BONMIN_SYSTEM to link to Bonmin system library;
• CARGO_IPOPT_STATIC to link to Ipopt statically;
• CARGO_IPOPT_SYSTEM to link to Ipopt system library;
• CARGO_MUMPS_STATIC to link to Mumps statically;
• CARGO_MUMPS_SYSTEM to link to Mumps system library;
• 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;
• CARGO_OSI_SYSTEM to link to Osi system library;
• CARGO_CLP_STATIC to link to Clp statically;
• CARGO_CLP_SYSTEM to link to Clp system library;
• CARGO_CGL_STATIC to link to Cgl statically;
• CARGO_CGL_SYSTEM to link to Cgl system library;
• CARGO_CBC_STATIC to link to Cbc statically;
• CARGO_CBC_SYSTEM to link to Cbc 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.

If you enable OpenBLAS(openblas-src), you can also pass env to make by OPENBLAS_*. Read more at here

bonmin-src = { version = "\*", default-features = no }
ipopt-src = { version = "\*", features = ["intel-mkl", "intel-mkl-lp64-seq"] }

On Windows, openblas need vcpkg to find Bonmin. Before building, you must have the correct Bonmin installed for your target triplet and kind of linking. For instance, to link dynamically for the x86_64-pc-windows-msvc toolchain, install bonmin for the x64-windows triplet:

vcpkg install bonmin --triplet x64-windows

To link Bonmin statically, install bonmin for the x64-windows-static-md triplet:

vcpkg install bonmin --triplet x64-windows-static-md

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

vcpkg install bonmin --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.

If you use OpenBLAS(openblas-src), you need to set OPENBLAS_CC, OPENBLAS_FC, OPENBLAS_HOSTCC, and OPENBLAS_TARGET to pass env to OpenBLAS, ref:openblas-src and OpenBLAS. For example:

export OPENBLAS_TARGET=ARMV8
export OPENBLAS_HOSTCC=gcc
export OPENBLAS_CC=aarch64-linux-gnu-gcc
export OPENBLAS_FC=aarch64-linux-gnu-gfortran

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

Note: intel-mkl-* can only be used for x86_64-*.openblas-static can only be used for linux.
