Docs

Building

This library depends upon nlopt and will fail if it cannot find a library to link against.

For Linux, it is recommended to clone nlopt from github (the official release is many years behind master) and follow the installation docs. You may find it more convenient the build nlopt as a static library, by passing -DBUILD_SHARED_LIBS=OFF to cmake.

Windows is a bit more tricky. One way is to download the precompiled binary and turn it into nlopt.lib by executing

lib.exe /def:libnlopt-0.def /out:nlopt.lib /MACHINE:x64`

(This requires the Visual Studio development tools to be installed).

For either platform, the resulting object must be on the search path at link-time. This can be set with environment variables, the rustc command or a build.rs script.

Tests

cargo test
