UnsatisfiedLinkError when running TypeDB on an M1 MacBook

Question

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?

Answer 1

As of the TypeDB 2.19.0 release, the mac and linux distributions support both x86_64/amd64 and arm64/aarch64 architectures natively.

These versions are faster than using emulation to run the x86_64 distributions on Macs in particular.

Installation is now as simple as installing a Java runtime that is applicable to your native OS+architecture, and then installing TypeDB for your OS via the apt/brew distribution channels or from the Github releases page: https://github.com/vaticle/typedb/releases

Answer 2

TypeDB v2.19 or above

As of TypeDB 2.19.0, TypeDB supports native Mac and Linux arm architectures. Simply install a native Java runtime to run TypeDB.

Old versions of TypeDB

⚠️ Prior to TypeDB 2.19.0, there were no distributions available for aarch64 (ARM). As of Jul 6, 2023, the best solution is to upgrade to TypeDB 2.19.0 or above. If doing so through Homebrew, ensure you are using an ARM64 installation of brew (i.e. the default).

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 <v2.19, so in order for older versions of 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 Eclipse Temurin (based upon OpenJDK):

1. Visit https://adoptium.net/en-GB/temurin/releases/?version=11 to browse Temurin releases
2. Select the .pkg distribution of JDK 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.

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.
