Build

To build zwaves.jar we need to cross compile the library for Linux, Windows and MacOS. This HOWTO is working for rust 1.38+ stable and Ubuntu 64bit.

If cross compilation for i686 windows broken in your enviroment

Build dll for win32 in native enviroment Comment lines for i686 in build_all.sh

Install gradle

Install gradle.

Install dependencies and add targets

# Install dependencies for cross compilation Linux to MacOS
apt install cmake clang gcc g++ zlib1g-dev libmpc-dev libmpfr-dev libgmp-dev libxml2-dev libssl-dev gcc-multilib libc6-dev-i386 mingw-w64

# Install dependencies for cross compilation Linux to Windows
apt install mingw-w64

# Install dependencies for compilation 32bit binary
apt install gcc-multilib libc6-dev-i386


# Add Rust targets

rustup target add x86_64-apple-darwin
rustup target add i686-pc-windows-gnu
rustup target add x86_64-pc-windows-gnu
rustup target add i686-unknown-linux-gnu
rustup target add x86_64-unknown-linux-gnu

Build jar

# build jar file
./build_all.sh 

Get zwaves.jar from javalib/build/libs/zwaves.jar.
