Cbc-src
Cbc-src
crate is a *-src crate. This links Cbc libraries to executable build by cargo, but does not provide Rust bindings. Cbc is built with CoinUtils (CoinUtils-src), Osi (Osi-src), Cgl (Cgl-src) and Clp (Clp-src).
By this package, you don't need to worry about installing CBC in the system, and it can be built for all platforms.
Cbc (Coin-or branch and cut) is an open-source mixed integer linear programming solver written in C++. It can be used as a callable library or using a stand-alone executable. It can be used in a wide variety of ways through various modeling systems, packages, etc.
Usage
-
Add the following to your
Cargo.toml
:[dependencies] cbc-src = "\*"
-
Add the following to your
lib.rs
:extern crate cbc_src;
This package does not provide bindings. Please use coincbc-sys, coinclp-sys to use Cbc, Clp, e.g.
[dependencies]
coincbc-sys = { version = "\*" }
Configuration
Features
The following Cargo features are supported:
default
toosicbc
andcbcsolver
feature;osicbc
to build withOsi
supported. However theOsi
is always built, by which theCbc
call theClp
solver andCgl
library;cbcsolver
to buildCbcSolver
lib and crate the api forRust
. If you do not useCbc
directly, you can disable this feature to reduce the build time;
Environment
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;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
.
Windows and vcpkg
On Windows, if ${LIB_NAME}_SYSTEM
is set to 1
, cbc-src
will use
vcpkg to find Cbc. Before building, you must have the correct Cbc
installed for your target triplet and kind of linking. For instance,
to link dynamically for the x86_64-pc-windows-msvc
toolchain, install
cbc
for the x64-windows
triplet:
vcpkg install cbc --triplet x64-windows
To link Cbc statically, install cbc
for the x64-windows-static-md
triplet:
vcpkg install cbc --triplet x64-windows-static-md
To link Cbc and C Runtime (CRT) statically, install cbc
for the x64-windows-static
triplet:
vcpkg install cbc --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
.
