The slowdebug version cannot be compiled.

I compiled the release version correctly.

errors：

What system (OS, libc version) are you building it on? It seems to be complaining about not being able to find gettid. Sounds like the libc version you're using may be old

I use docker from https://github.com/mmtk/mmtk-dev-env/Dockerfile.

I change the OS version to Ubuntu 20.04.6 LTS，everything is ok!

Oh sorry. We've stopped using that Dockerfile and it's clearly gone stale. Thank you for reporting that.

We use Ubuntu 22.04 for our CI. So you should be able to use that and it would work.

The Dockerfile is still in use, and we regularly check in the CI to make sure that it is working. However, we do not build OpenJDK within the docker (we just build mmtk-core). I add a CI job to build OpenJDK in the docker in mmtk/mmtk-dev-env#6. Thanks for reporting the issue.

I will update the base image for the docker file as well.
