Redox: A Rust Operating System

Redox is an operating system written in pure Rust, designed to be modular and secure. The development blog can be found at http://www.redox-os.org.

Documentation can be found here.

Please make sure you use the latest nightly of rustc before building (for more troubleshooting, see "Help! Redox won't compile!").

Help! Redox won't compile!

Sometimes things go wrong when compiling. Try the following before opening an issue:

1. Run make clean.
2. Run git clean -X -f -d.
3. Make sure you have the latest version of Rust nightly! (multirust is recommended for managing Rust versions).
4. Update GNU Make, NASM and QEMU/VirtualBox.
5. Pull the upstream master branch (git remote add upstream [email protected]:redox-os/redox.git; git pull upstream master).

and then rebuild!

Contributing to Redox

If you're interested in this project, and you'd like to help us out, here is a list of ways you can do just that.

Cloning, Building, and Running

Redox is big (even compressed)! So cloning Redox takes a lot bandwidth, and (depending on your data plan) can be costly, so clone at your own risk!

Quick Setup

$ cd path/to/your/projects/folder/

# Run bootstrap setup
$ curl -sf https://raw.githubusercontent.com/redox-os/redox/master/bootstrap.sh -o bootstrap.sh && bash -e bootstrap.sh

# Build Redox
$ make all

# Launch using QEMU
$ make qemu
# Launch using QEMU without using KVM (Kernel Virtual Machine). Try if QEMU gives an error.
$ make qemu kvm=no

QEMU with KVM

To use QEMU with KVM (kernel-based virtual Machine), which is faster than without KVM, you need a CPU with Intel® Virtualization Technology (Intel® VT) or AMD Virtualization™ (AMD-V™) support. Most systems have this disabled in the BIOS by default, so you may need to reboot and enable the feature in the BIOS.

Manual Setup

To manually clone, build and run Redox using a Linux host, run the following commands (with exceptions, be sure to read the comments):

$ cd path/to/your/projects/folder/

# HTTPS
$ git clone https://github.com/redox-os/redox.git --origin upstream --recursive
# SSH
$ git clone [email protected]:redox-os/redox.git --origin upstream --recursive

$ cd redox/

# Install/update dependencies
$ sudo <your package manager> install make nasm qemu

# Install multirust
$ curl -sf https://raw.githubusercontent.com/brson/multirust/master/quick-install.sh | sh

# Set override toolchain to nightly build
$ multirust override nightly

# For successive builds start here. If this is your first build, just continue

# Update git submodules
$ git submodule update --recursive --init

# Build Redox
$ make all

# Launch using QEMU
$ make qemu
# Launch using QEMU without using KVM (Kernel Virtual Machine). Try if QEMU gives an error.
$ make qemu kvm=no
