How to build leveldb-jna?

Sources

  1. Download leveldb-jna from repository and install sub-modules:

    git clone git@github.com:protonail/leveldb-jna.git
cd leveldb-jna
git submodule init
git submodule update

Prepare Environment

Windows Platform

  1. Install MSYS2 for correspond architecture.

  2. Open MinGW shell correspond to platform architecture (MinGW-w64 Win64 Shell or MinGW-w64 Win32 Shell).

  3. Update the system packages:

    pacman --needed -Sy bash pacman pacman-mirrors msys2-runtime

  4. (!!!) Close MSYS2, run it again from Start menu and update the rest:

    pacman -Su

  5. Install packages for development:

     pacman -S base-devel git

  6. Install toolchain for correspond architecture:

    For Windows x64:

    pacman -S mingw-w64-x86_64-toolchain

    For Windows x86:

    pacman -S mingw-w64-i686-toolchain

OS X Platform

  1. Install packages required for build:

    brew install automake libtool pkg-config

Linux Platform (i.e. Ubuntu)

  1. Install packages required for build:

    apt-get install build-essential
apt-get install automake libtool pkg-config

Build Native Platform Dependent Library

You should repeat these steps for each platform.

  1. Open leveldb-jna root directory and execute build script:

    bin/build_leveldb.sh clean

    It should build Snappy and LevelDB and copy correspond native library file to leveldb-jna-native/src/main/resources/<JNA platform identificator>/<library name>.{so,dylib,dll}.

  2. Run tests

    mvn test

  3. Build Java library with native binaries inside and deploy it to remote Maven repository:

    mvn deploy -DaltSnapshotDeploymentRepository=<altSnapshotDeploymentRepository> -DaltReleaseDeploymentRepository=<altReleaseDeploymentRepository> -pl leveldb-jna-native

    where altSnapshotDeploymentRepository and altReleaseDeploymentRepository is your Maven repositories (i.e. run on Nexus Sonatype). Details is here.

Build Core Library

  1. Build Core Java library and deploy it to remote Maven repository:

    mvn deploy -DaltSnapshotDeploymentRepository=<altSnapshotDeploymentRepository> -DaltReleaseDeploymentRepository=<altReleaseDeploymentRepository> -pl leveldb-jna-core

    where altSnapshotDeploymentRepository and altReleaseDeploymentRepository is your Maven repositories (i.e. run on Nexus Sonatype). Details is here.

That's all.
