Here is my deps jvm config

{:jvm-opts ["--add-opens=java.base/java.nio=ALL-UNNAMED"
              "--add-opens=java.base/sun.nio.ch=ALL-UNNAMED"
              #_"--enable-native-access=ALL-UNNAMED"
              "-Djava.library.path=/Users/ryan/.javacpp/cache/dtlvnative-macosx-arm64-0.12.8.jar/datalevin/dtlvnative/macosx-arm64"]}

Here is the error with none of those jvm config flags loaded

Here is what it looks like from when I try to install libs

brew install libomp llvm

And i rebooted terminal tab

Is this a complication?

your Homebrew is running under Rosetta.

Your Mac is Apple Silicon (arm64), but Homebrew is installed at /usr/local, which is the Intel x86_64 prefix. On Apple Silicon Macs, the native ARM version of Homebrew installs to /opt/homebrew.

This means all packages installed via this Homebrew instance will run under Rosetta 2 (Apple's x86_64 emulation).

I am seeing this exact same error on my new Mac. My homebrew is under /opt/homebrew and appears to not be using Rosetta. I see the same error when I try to load dataleven libraries in a require. I am running MacOS Sequoia 15.7.2 on a brand new M3 mac. The library loads in a podman container and on my linux machine, but on the new mac fails with the error: Library not loaded: libdtlv.dylib

You are having different problems. Brand new MacOS may have too new libraries, while some are using rossenta. The CI build machine for 0.9.22 was latest-maosx I believe, but that's half a year ago. The current master branch build with maces-14, which works well on my MacOSX 15.6.1. So Really, it's about the version mismatch. That's the price to pay for going native.

Im trying to migrate my homebrew setup to arm to see if that helps. i am running osx 15.6.1

The one running the new Mac , make sure you read the instructions and install the native dependencies. These are the common dependencies for a dev machine, not something strange.

After migrating homebrew installs and config, it is working for me! 🙌 Thanks for commenting

Yes thank you for the pointer, I was able to brew install the native deps (libomp llvm) and datalevin is now working great on my new Mac.

Slightly? It's like 41% improvement 🚀 😅

After tuning the magic numbers of the optimizers a bit, Datalevin now is twice faster than PostgreSQL in JOB benchmark 🙂
