§Osi-src
§description
Osi-src crate is a *-src crate. This links Osi libraries to executable build by cargo, but does not provide Rust bindings.Osi build with CoinUtils (CoinUtils-src) support.
By this package, you don’t need to worry about installing Osi in the system, and it’s a package for all platforms.
Osi (Open Solver Interface) provides an abstract base class to a generic linear programming (LP) solver, along with derived classes for specific solvers. Many applications may be able to use the Osi to insulate themselves from a specific LP solver. That is, programs written to the OSI standard may be linked to any solver with an OSI interface and should produce correct results. The OSI has been significantly extended compared to its first incarnation. Currently, the OSI supports linear programming solvers and has rudimentary support for integer programming.
§Usage
-
Add the following to your
Cargo.toml
:[dependencies] osi-src = "\*"
-
Add the following to your
lib.rs
:extern crate osi_src;
This package does not provide bindings. Please use coincbc-sys, coinclp-sys to use Cbc, Clp, e.g.
[dependencies]
coincbc-sys = { version = "0.2" }
§Configuration
§Features
The following Cargo features are supported:
default
to buildOsi
without any solver support;osicpx
to enable the Cplex support;osiglpk
to enable the GLPK support;osigrb
to enable the Gurobi support;osimsk
to enable the Mosek support;osispx
to enable the Soplex support;osixpr
to enable the XPRESS support;
§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;
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
, osi-src
will use
vcpkg to find Osi. Before building, you must have the correct Osi
installed for your target triplet and kind of linking. For instance,
to link dynamically for the x86_64-pc-windows-msvc
toolchain, install
osi
for the x64-windows
triplet:
vcpkg install osi --triplet x64-windows
To link Osi statically, install osi
for the x64-windows-static-md
triplet:
vcpkg install osi --triplet x64-windows-static-md
To link Osi and C Runtime (CRT) statically, install osi
for the x64-windows-static
triplet:
vcpkg install osi --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
.
