Building a cross-platform JAR requires:
* [Vagrant](https://www.vagrantup.com/)
* [Virtualbox](https://www.virtualbox.org/)
* [Docker](https://www.docker.com/docker-community)
* A Mac OSX machine that can compile RocksDB.
* Java 7 set as JAVA_HOME.
Once you have these items, run this make command from RocksDB's root source directory:
make jclean clean rocksdbjavastaticrelease
make jclean clean rocksdbjavastaticreleasedocker
This command will build RocksDB natively on OSX, and will then spin up two Vagrant Virtualbox Ubuntu images to build RocksDB for both 32-bit and 64-bit Linux.
This command will build RocksDB natively on OSX, and will then spin up docker containers to build RocksDB for 32-bit and 64-bit Linux with glibc, and 32-bit and 64-bit Linux with musl libc.
You can find all native binaries and JARs in the java/target directory upon completion:
