Using xgboost4j

This project publishes xgboost4j to Maven central that contains portable binaries for MacOSX and Linux. DMLC's xgboost is a great library but, as seen in this issue, it is not published to maven central yet.

<dependency>
    <groupId>io.github.myui</groupId>
    <artifactId>xgboost4j</artifactId>
    <version>0.90-rc2</version>
</dependency>

Portability

Update shared library in jar

jar uf xgboost4j-0.90-rc2.jar lib/libxgboost4j.dylib
jar tf xgboost4j-0.90-rc2.jar | grep libxgboost4j

Compilied shared libraries (i.e., libxgboost4j.dylib|so) are a portable one without dependencies to openmp and libc++ (for linux) as follows: Minimum requirement for GLIBC is 2.15.

xgboost4j/src/main/resources/lib/libxgboost4j.dylib:
    @rpath/libxgboost4j.dylib (compatibility version 0.0.0, current version 0.0.0)
    @rpath/libjvm.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.1.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

xgboost4j/src/main/resources/lib/libxgboost4j.so:
	linux-vdso.so.1 =>  (0x00007ffe475bc000)
	librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f1ca5f8d000)

	/lib64/ld-linux-x86-64.so.2 (0x00007f1ca681d000)

$ strings xgboost4j/src/main/resources/lib/libxgboost4j.so | grep ^GLIBC | sort
GLIBC_2.14
GLIBC_2.2.5
GLIBC_2.3
GLIBC_2.3.2

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