[linux] Build on aarch64 required java library path tweaks in ant config files (attached)

[clort81]

Clone the repository:

git clone https://github.com/bondolo/tribaltrouble.git

Make sure you have Java SDK at least version 8, and Apache Ant.

To build the game client, do this:

cd tt
ant run

What is the command to start the game after building, if not using 'ant'?
Since i'm not on x86, I need to override the java.library.path for libraries that assume AMD64.

P.S. Here is my current java environment.

$ java -Djava.library.path=/usr/java/packages/lib/aarch64:/usr/lib/aarch64-linux-gnu/jni:/usr/lib/jvm/java-8-openjdk-arm64/jre/lib/aarch64:/lib/aarch64-linux-gnu:/usr/lib/aarch64-linux-gnu:/usr/lib/jni:/lib:/usr/lib  -XshowSettings:properties

I have patched two ant build files that got me to a working game by overriding the java library paths.
Attached here and closing the issue.
buildpatches_mylinux.zip

Works splendidly on khadas vim3 with panfrost drivers.
Thank you for your work on this! It is a very nice procedural terrain generator to study.

Re-opening so master Bondolo might see it more easily. :)

[Mike Duigou]

Could you submit the changes as a pull request?

[clort81]

These are the tweaked paths that work for me.
I am not a java programmer and I do not know how to make library path changes that would work on other computers. For this reason I think a pull request would be inappropriate.
