<div dir="ltr">Hello all,
<div><br>
</div>
<div>I'm trying to generate jextract types for io_uring (I didn't find any non-JNI/JNA libraries to use it from JVM)</div>
<div>Unfortunately, following the instructions I've hit a snag.<br>
</div>
<div><br>
</div>
<div>Building it with JDK 19, I get:</div>

<div>=============================================</div>

<div>Would it make sense to add a Dockerfile for Linux to the repo that can reliably build the latest version?</div>
<div>That way folks don't have to mess around with finding and installing LLVM and whatnot.</div>
<div><br>
</div>
<div>I'm happy to submit a PR for this if someone can tell me why the regular build command is failing, ha.</div>
