Repository to build Java LightGBM package for Linux/MacOSX. 

When pushing a tag to git, TravisCI automatically creates a release.

# Using lightgbm

This project publishes lightgbm to Maven central that contains portable binaries for MacOSX and Linux. 

```

    io.github.myui

    lightgbm

    3.2.1-rc1

```

# Portability

# Update shared library in jar

```sh

$ jar uf lightgbm-3.2.1-rc1.jar com/microsoft/ml/lightgbm/osx/x86_64/lib_lightgbm.dylib

$ jar uf lightgbm-3.2.1-rc1.jar com/microsoft/ml/lightgbm/osx/x86_64/lib_lightgbm_swig.dylib

$ jar tf lightgbm-3.2.1-rc1.jar | grep lib_lightgbm

com/microsoft/ml/lightgbm/linux/x86_64/lib_lightgbm.so

com/microsoft/ml/lightgbm/linux/x86_64/lib_lightgbm_swig.so

com/microsoft/ml/lightgbm/osx/x86_64/lib_lightgbm.dylib

com/microsoft/ml/lightgbm/osx/x86_64/lib_lightgbm_swig.dylib

```

Compilied shared libraries (i.e., liblightgbm.dylib|so) are a portable one without dependencies to openmp and libc++ (for linux) as follows:

Minimum requirement for GLIBC is [2.15](https://abi-laboratory.pro/tracker/timeline/glibc/).

```sh

$ otool -L com/microsoft/ml/lightgbm/osx/x86_64/*.dylib

You can find requirements in your environment by `strings /lib/x86_64-linux-gnu/libc.so.6 | grep ^GLIBC | sort`.
