By default SDL will only link against glibc, the rest of the features will be enabled dynamically at runtime depending on the available features on the target system. So, for example if you built SDL with XRandR support and the target system does not have the XRandR libraries installed, it will be disabled at runtime, and you won't get a missing library error, at least with the default configuration parameters.

Build Dependencies

Ubuntu 18.04, all available features enabled:

sudo apt-get install build-essential git make \
pkg-config cmake ninja-build gnome-desktop-testing libasound2-dev libpulse-dev \
libaudio-dev libfribidi-dev libjack-dev libsndio-dev libx11-dev libxext-dev \
libxrandr-dev libxcursor-dev libxfixes-dev libxi-dev libxss-dev libxtst-dev \

libegl1-mesa-dev libdbus-1-dev libibus-1.0-dev libudev-dev libthai-dev

Ubuntu 22.04+ can also add libpipewire-0.3-dev libwayland-dev libdecor-0-dev liburing-dev to that command line.

Fedora 35, all available features enabled:

sudo dnf install gcc git-core make cmake \
alsa-lib-devel fribidi-devel pulseaudio-libs-devel pipewire-devel \
libX11-devel libXext-devel libXrandr-devel libXcursor-devel libXfixes-devel \
libXi-devel libXScrnSaver-devel libXtst-devel dbus-devel ibus-devel \
systemd-devel mesa-libGL-devel libxkbcommon-devel mesa-libGLES-devel \
mesa-libEGL-devel vulkan-devel wayland-devel wayland-protocols-devel \
libdrm-devel mesa-libgbm-devel libusb1-devel libdecor-devel \
pipewire-jack-audio-connection-kit-devel libthai-devel

Fedora 39+ can also add liburing-devel to that command line.

Fedora 40+ needs zlib-ng-compat-static to be added to that command line.

NOTES: - The sndio audio target is unavailable on Fedora (but probably not what you should want to use anyhow).

openSUSE Tumbleweed:

sudo zypper in libunwind-devel libusb-1_0-devel Mesa-libGL-devel libxkbcommon-devel libdrm-devel \

Joystick does not work

If you compiled or are using a version of SDL with udev support (and you should!) there's a few issues that may cause SDL to fail to detect your joystick. To debug this, start by installing the evtest utility. On Ubuntu/Debian:

sudo apt-get install evtest

Then run:

sudo evtest

You'll hopefully see your joystick listed along with a name like "/dev/input/eventXX" Now run:

cat /dev/input/event/XX

If you get a permission error, you need to set a udev rule to change the mode of your device (see below)

Also, try:

sudo udevadm info --query=all --name=input/eventXX

If you see a line stating ID_INPUT_JOYSTICK=1, great, if you don't see it, you need to set up an udev rule to force this variable.

A combined rule for the Saitek Pro Flight Rudder Pedals to fix both issues looks like:

SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
SUBSYSTEM=="input", ATTRS{idProduct}=="0764", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"

You can set up similar rules for your device by changing the values listed in idProduct and idVendor. To obtain these values, try:

sudo udevadm info -a --name=input/eventXX | grep idVendor
sudo udevadm info -a --name=input/eventXX | grep idProduct

If multiple values come up for each of these, the one you want is the first one of each.

On other systems which ship with an older udev (such as CentOS), you may need to set up a rule such as:

SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1"
