Nathan Wallace 0c0a760aad Meta+Documentation: Bump required QEMU version
This commit bumps the required QEMU version to 6.2 and updates the
version checking logic in Meta/run.sh to support checking against
major and minor version numbers instead of checking against the major
version only

SerenityOS build instructions

Prerequisites

Make sure you have all the dependencies installed:

Debian / Ubuntu

sudo apt install build-essential cmake curl libmpfr-dev libmpc-dev libgmp-dev e2fsprogs ninja-build qemu-system-gui qemu-system-x86 qemu-utils ccache rsync unzip texinfo

Optional: fuse2fs for building images without root.

GCC 11

On Ubuntu gcc-11 is available in the repositories of 21.04 (Hirsuite) and later - add the ubuntu-toolchain-r/test PPA if you're running an older version:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

Next, update your local package information from this repository:

sudo apt update

Now on Ubuntu or Debian you can install gcc-11 with apt like this:

sudo apt install gcc-11 g++-11

QEMU 6.2 or later

Version 6.2 of QEMU is available in Ubuntu 22.04. On earlier versions of Ubuntu, you can build the recommended version of QEMU as provided by the toolchain by running Toolchain/BuildQemu.sh. Note that you might need additional dev packages in order to build QEMU on your machine:

sudo apt install libgtk-3-dev libpixman-1-dev libsdl2-dev libspice-server-dev

Windows

If you're on Windows you can use WSL2 to build SerenityOS. Please have a look at the Windows guide for details.

Arch Linux / Manjaro

sudo pacman -S --needed base-devel cmake curl mpfr libmpc gmp e2fsprogs ninja qemu-desktop qemu-system-x86 qemu-system-aarch64 ccache rsync unzip

Optional: fuse2fs for building images without root.

Other systems

There is also documentation for installing the build prerequisites for some less commonly used systems:

Build

In order to build SerenityOS you will first need to build the toolchain by running the following command:

Meta/serenity.sh rebuild-toolchain

Later on, when you use git pull to get the latest changes, there's (usually) no need to rebuild the toolchain.

Run the following command to build and run SerenityOS:

Meta/serenity.sh run

This will compile all of SerenityOS and install the built files into the Build/i686/Root directory inside your Git repository. It will also build a disk image and start SerenityOS using QEMU.

Note that the anon user is able to become root without a password by default, as a development convenience. To prevent this, remove anon from the wheel group and he will no longer be able to run /bin/su.

By default the anon user account's password is: foo

If you want to test whether your code changes compile without running the VM you can use Meta/serenity.sh build. The serenity.sh script also provides a number of other commands. Run the script without arguments for a list.

Ports

To add a package from the ports collection to Serenity, for example curl, change into the Ports/curl directory and run ./package.sh. The source code for the package will be downloaded and the package will be built. The next time you start Serenity, curl will be available.

More information

At this point you should have a fully functioning VM for SerenityOS. The advanced build instructions guide has more information for some less commonly used features of the build system.
