Redox is an operating system written in Rust, a language with focus on safety and high performance. Redox, following the microkernel design, aims to be secure, usable, and free. Redox is inspired by previous kernels and operating systems, such as SeL4, MINIX, Plan 9, and BSD.

Redox is not just a kernel, it's a full-featured Operating System, providing packages (memory allocator, file system, display manager, core utilities, etc.) that together make up a functional and convenient operating system. You can loosely think of it as the GNU or BSD ecosystem, but in a memory safe language and with modern technology. See this list for overview of the ecosystem.

The website can be found at https://www.redox-os.org.

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. Make sure you have a Redox toolchain (x86_64-unknown-redox-gcc).
    • You can install from .deb packages (https://static.redox-os.org/toolchain/apt/) or build redox-os/libc manually.
  2. Run rustup update
  3. Run make clean pull.
  4. Make sure you have the latest version of Rust nightly! (rustup.rs is recommended for managing Rust versions. If you already have it, run rustup).
  5. Update GNU Make, NASM and QEMU/VirtualBox.
  6. Pull the upstream master branch (git remote add upstream git@github.com:redox-os/redox.git; git pull upstream master).
  7. Update submodules (git submodule update --recursive --init).

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. Downloading the full history may take a lot of bandwidth, and can even be costly on some data plans. 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

#Change to project directory
$ cd redox

# Build Redox
$ make all

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


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 by default, so you may need to reboot, go into the BIOS, and enable it.

Manual Setup

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

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

$ git clone https://github.com/redox-os/redox.git --origin upstream --recursive
$ git clone git@github.com:redox-os/redox.git --origin upstream --recursive

$ cd redox/

# Install/update dependencies
$ ./bootstrap.sh -d

# Install rustup.rs
$ curl https://sh.rustup.rs -sSf | sh

# Install the sysroot manager Xargo
$ cargo install xargo

# 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-based Virtual Machine). Try if QEMU gives an error.
$ make qemu kvm=no

# Launch using QEMU without using KVM (Kernel-based Virtual Machine) nor Graphics
make qemu kvm=no vga=no

Setup using Docker

We also provide docker image. After cloning this repository, please follow README under the docker directory.

Updating the codebase using the Makefile

To update the codebase run:

make pull; make fetch

make pull pulls and updates the submodules, and make fetch updates the sources for cookbook recipes.

redox latest release notes
0.3.4 0.3.4 - Filesystem UUID

ISO Downloads

This release focuses on changes to RedoxFS, the bootloader, and the kernel to enable filesystem UUIDs.

The basic logic is this:

  • The bootloader loads the kernel from RedoxFS on the disk it is present on
  • The bootloader passes the UUID as an environmental variable to the kernel
  • The kernel passes the environmental variables to the init process
  • The init script for the init filesystem passes this UUID as an argument to RedoxFS
  • RedoxFS searches all available disks for a filesystem matching this UUID, and mounts it as the root filesystem

This was particularly important for the installation of Redox.

0.3.3 0.3.3 - Lower Memory Usage

ISO Downloads Travis Build Log

This release brings much lower memory usage with ISO - 480 MB instead of 1300 MB. There are also other bug fixes, features, and improvements.

Download the ISO here.

VirtualBox with Intel PRO/1000 Ethernet will be the most feature-complete experience. Only 64-bit x86 systems are supported. Give the VM at least 1 GB of RAM for the best results. The default username is user with an empty password. There is also a root user with a password of password.
