Rust standard library for OpenWRT

What is this

This package will install rust's libstd as a dynamic *.so library in the /usr/lib folder of your OpenWRT device. This allows for very small rust binaries to be compiled which is required for OpenWRT use.

Requirements

For this example to work you need to have the lang/rust package from Grommish. This package will build the rustc compiler and the cargo application from source tuned for use with dynamically linked musl and softfloat MIPS and MIPS64 targets.

Compilation

To compile this minimal working example the following steps must be taken:

1. Install and build the requirements.
2. Clone this repository in the package/lang directory of the OpenWRT toolchain.
3. Execute make menuconfig in the toolchain root and select the rust-libstd library in the Languages menu either with a * or M selector.
4. Build the package by executing make V=s package/rust-libstd/{clean,compile} in the root of the toolchain.

When everything goes succesfull you now have an installable ipk in the bin/packages/ directory.
