Run java-tron on ARM - AWS Arm-based Graviton2 instances / Apple M1

1. What did you do?

We are trying to run FullNode.jar on x2gd.large ARM based instance with Amazon Corretto installed, but get the error:

# Install Amazon Corretto 8
amazon-linux-extras install corretto8

# Install Java Tron
mkdir java-tron
cd java-tron
curl -L https://github.com/tronprotocol/java-tron/releases/download/GreatVoyage-v4.4.1/FullNode.jar -o FullNode-4.4.1.jar
curl https://raw.githubusercontent.com/tronprotocol/tron-deployment/master/main_net_config.conf -o main_net_config.conf

# Run java-tron
java -Xmx25g -XX:+UseConcMarkSweepGC -jar FullNode-4.4.1.jar -d data -c main_net_config.conf

And get the error

2. What did you expect to see?

We should be able to run java-tron on ARM based architecture.

3. What did you see instead?

For now we are running java-tron on x86-64 architecture.

During last years Amazon WS introduced a lot of ARM based instances and they have a great performance and affordable price. Also, Apple started a movement to the ARM architecture which is actual for Developers. It will be great to have an option to run java-tron using ARM architecture.

Thank you!

[Benson0224]

can you share your java version info

We are use Amazon Corretto 8

java -version
openjdk version "1.8.0_302"
OpenJDK Runtime Environment Corretto-8.302.08.1 (build 1.8.0_302-b08)
OpenJDK 64-Bit Server VM Corretto-8.302.08.1 (build 25.302-b08, mixed mode)

And one more try with Oracle Java

Get Oracle Java for ARM

curl -L https://javadl.oracle.com/webapps/download/AutoDL?BundleId=243705_61ae65e088624f5aaa0b1d2d801acb16 -o jdk-8u271-linux-aarch64.rpm

Install Oracle Java for ARM

yum install jdk-8u271-linux-aarch64.rpm

Check Java version

java version "1.8.0_271"
Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)

Get java-tron and config

mkdir java-tron
cd java-tron
curl -L https://github.com/tronprotocol/java-tron/releases/download/GreatVoyage-v4.4.1/FullNode.jar -o FullNode-4.4.1.jar
curl https://raw.githubusercontent.com/tronprotocol/tron-deployment/master/main_net_config.conf -o main_net_config.conf

Run java-tron

java -Xmx25g -XX:+UseConcMarkSweepGC -jar FullNode-4.4.1.jar -d data -c main_net_config.conf

Get the error

Looks like your system does not have Librocksdb.so
I would suggest you google and install the related lib and try again.

Java on Graviton

It is a shared library and should be included in the jar?

Check GutHub jar

Get FullNode-4.4.1.jar

curl -L https://github.com/tronprotocol/java-tron/releases/download/GreatVoyage-v4.4.1/FullNode.jar -o FullNode-4.4.1.jar
