Linux Java library linking issue?

[Julien Roubieu]

Hello everyone,

I'm building from source to be able to use `addDimensionWithVehicleTransits` that was recently added to the Java lib.

I'm having an issue running the lib on Linux. I guess I forgot something in the build process, maybe someone knows what it could be and give me a hint.

Building and running for OSX works perfectly.

Building for Linux on a Debian 8 box completes successfully (`make third_party cc java test_java`).

However my program fails on the call to `System.loadLibrary`, with the following error:

```

Started with java.library.path = /opt/docker/lib

Exception in thread "main" java.lang.UnsatisfiedLinkError: /opt/docker/lib/libjniortools.so: libortools.so: cannot open shared object file: No such file or directory

at java.lang.ClassLoader$NativeLibrary.load(Native Method)

at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941)

at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857)

at java.lang.Runtime.loadLibrary0(Runtime.java:870)

at java.lang.System.loadLibrary(System.java:1122)

```

`libortools.so` is in the lib directory.

If I replace `libjniortools.so` with the one from the latest 5.1 release, the library is loaded without this exception (although it obviously fails later).

Does someone have an idea why the libjniortools I built cannot find libortools?
