UnsatisfiedLinkError when running TypeDB on an M1 MacBook

I tried running TypeDB on my M1 MacBook using ./typedb server, but it results in the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /var/folders/5v/95_mbj013y93vsmc8xps0stm0000gp/T/librocksdbjni8182124459810412816.jnilib
    at java.base/java.lang.ClassLoader.loadLibrary(ClassLoader.java:2393)
    at java.base/java.lang.Runtime.load0(Runtime.java:755)
    at java.base/java.lang.System.load(System.java:1953)

This error looks like it might occur when running a Java program with an incompatible JDK. What can I do to resolve it?

If the running JDK targets aarch64 (ARM), the architecture used by an M1 Mac, then an UnsatisfiedLinkError is thrown at startup. There is no native ARM build of TypeDB yet, so in order for TypeDB to run correctly on an M1 MacBook you need to ensure that a JDK that targets x64 architecture is installed.

For example, to install from AdoptOpenJDK:

  1. Visit https://adoptopenjdk.net/releases.html to browse AdoptOpenJDK releases
  2. Select OpenJDK 11 with operating system MacOS and architecture x64
  3. Download and install the Java binary displayed in the list below
  4. Verify that Java was installed correctly by running java --version; the output should match the downloaded JDK version

Please note that this method relies on MacOS's Rosetta translation, which will inflict a performance overhead on the application.

My computer is MacBookAir M1. And I encountered this problem too.

I tried Java 17 and Java 8, and both were filed. Finally, when I switch to Java 11, the error disappeared. Hope this helps.
