Apparently, qemu-system-* changed its name. On Debian/Ubuntu, genext2fs does not make a difference: The only user of this command, Meta/build-image-qemu.sh, runs as root anyway, and tries to do 'mount _disk_image mnt/' first. Debian/Ubuntu always have drivers for ext2 available, so this command has no good reason to fail, and trying to use genext2fs might only obscure any problems that mount encountered. Finally, Debian Bullseye (released 2021-08-14) contains gcc-10, so the instructions on how to upgrade are now obsolete.

# SerenityOS build instructions
|
|
|
|
## Prerequisites
|
|
|
|
Make sure you have all the dependencies installed:
|
|
|
|
### Debian / Ubuntu
|
|
|
|
```console
|
|
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
|
|
```
|
|
|
|
#### GCC 10
|
|
|
|
On Ubuntu gcc-10 is available in the repositories of 20.04 (Focal) and later - add the `ubuntu-toolchain-r/test` PPA if you're running an older version:
|
|
|
|
```console
|
|
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
|
|
```
|
|
|
|
Now on Ubuntu or Debian you can install gcc-10 with apt like this:
|
|
|
|
```console
|
|
sudo apt install gcc-10 g++-10
|
|
```
|
|
|
|
#### QEMU 5 or later
|
|
|
|
QEMU version 5 is available in Ubuntu 20.10, but it is recommended to build Qemu as provided by the toolchain by running `Toolchain/BuildQemu.sh`.
|
|
Note that you might need additional dev packages:
|
|
|
|
```console
|
|
sudo apt install libgtk-3-dev libpixman-1-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](BuildInstructionsWindows.md)
|
|
for details.
|
|
|
|
### Arch Linux / Manjaro
|
|
|
|
```console
|
|
sudo pacman -S --needed base-devel cmake curl mpfr libmpc gmp e2fsprogs ninja qemu qemu-arch-extra ccache rsync unzip
|
|
```
|
|
|
|
### Other systems
|
|
|
|
There is also documentation for installing the build prerequisites for some less commonly used systems:
|
|
|
|
* [Other Linux distributions and \*NIX systems](BuildInstructionsOther.md)
|
|
* [macOS](BuildInstructionsMacOS.md)
|
|
|
|
## Build
|
|
|
|
In order to build SerenityOS you will first need to build the toolchain by running the following command:
|
|
|
|
```console
|
|
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:
|
|
|
|
```console
|
|
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](AdvancedBuildInstructions.md)
|
|
has more information for some less commonly used features of the build system.
