Ferrugo

Ferrugo is a JVM implementation written in Rust.

This is now just a toy project (for me/you to learn how it works).

Current Status

• Able to run some classfiles. see ./examples/(Hello|BigInt|SmallPT).class
• Partly support for JIT compiling powered by LLVM
• Aiming readable code (this is the hardest, yes)

Building from Source

Building on Linux

1. Install Rust

Run the command below and follow the onscreen instructions.

curl https://sh.rustup.rs -sSf | sh

2. Use Rust Nightly

rustup override set nightly

3. Install dependencies

• LLVM 6.0
• (Other packages as necessary...)

# e.g. Ubuntu or Debian
apt-get install llvm-6.0

4. Test

cargo test

5. Build and Run

cargo run --release examples/Hello.class

Building on other platforms

I don't know. Maybe almost the same as Linux.
