M3 MacBook Pro / aarch64 unable to run java-tron node.

[vn7n24fzkq]

While building a private Tron blockchain on my MacBook M3 Pro, it appears that the current version of java-tron does not support aarch64 architecture due to issues with rocksdb.
Are there any plans to upgrade rocksdb to support aarch64?
Alternatively, is there any other solution available?

Related to the following issues:

• Run java-tron on ARM - AWS Arm-based Graviton2 instances / Apple M1 #4132
• Java-tron - Release linux/arm64 builds #4692

Software Versions

OS : M3 MacBook Pro
JVM : Oracle Corporation 1.8.0_161 aarch64
Git : b1fc2f0f2bd79527099bc3027b9aba165c2e20c2
Version : 4.7.4

Expected behaviour

No errors should occur.

Actual behaviour

Encountered the following error:

This is a known issue, please compile and run with x86 jdk8 for now.

Here is a way using rosetta to run a java-tron node on you macbook pro (amd arch)
Firstly, Install rosetta，Command line: softwareupdate --install-rosetta

Secondly, Open a terminal using rosetta: From a Finder window, navigate to /Applications/Utilities and right-click Terminal and select Get Info. In the General section, check Open using Rosetta. run echo $(arch), You should see the response i386.

Thirdly, Download and install jdk1.8 x86 on this terminal, For example my download is jdk-8u391-macosx-x64.dmg, Install it like this

1. hdiutil attach jdk-8u391-macosx-x64.dmg
   2.sudo installer -pkg /Volumes/JDK\ 8\ Update\ 391/JDK\ 8\ Update\ 391.pkg -target /

After done all of the above, do the normal downloading building and running step of java-tron, You will be successful to run it on you macbook(amd arch)

Hope it can help you.
