Verbose compilation

Anyway to develop a progress bar for the compilation process? I found "preloadProgress" in CheerpJ docs for the init function but I'm pretty sure it doesn't provide information about how far the browser is with compiling the program.

Java Compilation on CheerpX and not CheerpJ

Hey i'm new to using Cheerpx, and I think its super cool! I've been playing around with my fork of https://github.com/leaningtech/webvm and seeing how I can change the Dockerfile. My current objective is to have Java work on my container. While I could just use Cheerpj, I wanted to be able to support user input through Scanner (and as far as I know, this isn't supported with CheerpJ) and also have more file flexibility. Has anyone figured out how to do it? Here's my Dockerfile: ```...

I've written a Linux manuscript and I'd like to host WebVM for the exercises.

Hello, I've written a Linux manuscript and I'd like to host WebVM in an environment for the exercises in the book. I plan to keep the environment free for anyone to use but customized with exercises so people can practice learning Linux while reading the book and if they want they can follow along with a Capture the Flag, for learning Linux. My reason for being here is to explore using WebVM before I start building the environment. My first question was if there is support, which it appears there is, next is there any licensing issue if I host it on my own domain and infrastructure, and would Learning Technologies be interested in a shout out in the book or some sort of relationship more than me using your product for my readers?...

I keep getting these errors when trying to run my Java app

I have compiled my Java code (including the dependencies) into a Jar file, which runs smoothly. However, when I try to use CheerpJ, I keep these errors.

Is WebVM faster on x86_64 hosts compared to arm64 MacOS hosts?

I am evaluating WebVM as a tool to sandbox a "playground" environment for a internal company compiler tool as it allows us the ability to run unmodified linux-x86 (does it support 64 bit binaries?) binaries which simplifies our execution environment as compared to compiling the compiler to WASM and writing JavaScript bindings. One concern I have is that the performance is quite poor - but I have only had the chance to evaluate it on an M1 MacBook Pro host so I am wondering if x86 translation is the cause of this poor performance? Is WebVM faster on an x86_64 host? If so, are there plans to add support for linux-arm64 virtualization so arm hosts can perform better?...

I always get [1:1] ELF execution failed [-2]: /opt/ibm/java/jre/bin/java error.

Or is there a way to get more debug logging?

CheerpJ issue returned

Hello, I have been trying to publish my game (currently on a Jar file) to an html page. I am not sure if there are some things that I am currently during wrong since I am unable to get my desired result. I attached the output (both on the UI and the terminal) as well as the code I currently have. It would be appreciated if I can fix this ASAP. Thanks!

Machine does not start completely: Unable to enter commands

Hello, I wanted to install cheerpx locally. I followed all the steps of the github but once deployed, the machine does not start. I have the interface but I can't enter commands. The "user@:~" never appears... I waited several hours but nothing happens. On the picture, it's already been running for 1 hour. How to do it? And forgive me for my English... I'm not an English speaker
