- Linux
- ================================================================================
-
- 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 autoconf automake libtool \
- pkg-config cmake ninja-build gnome-desktop-testing libasound2-dev libpulse-dev \
- libaudio-dev libjack-dev libsndio-dev libsamplerate0-dev libx11-dev libxext-dev \
- libxrandr-dev libxcursor-dev libxfixes-dev libxi-dev libxss-dev libwayland-dev \
- libxkbcommon-dev libdrm-dev libgbm-dev libgl1-mesa-dev libgles2-mesa-dev \
- libegl1-mesa-dev libdbus-1-dev libibus-1.0-dev libudev-dev fcitx-libs-dev
-
- Ubuntu 22.04+ can also add `libpipewire-0.3-dev libdecor-0-dev` to that command line.
-
- Fedora 35, all available features enabled:
-
- sudo yum install gcc git-core make cmake autoconf automake libtool \
- alsa-lib-devel pulseaudio-libs-devel nas-devel pipewire-devel \
- libX11-devel libXext-devel libXrandr-devel libXcursor-devel libXfixes-devel \
- libXi-devel libXScrnSaver-devel dbus-devel ibus-devel fcitx-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 libusb-devel libdecor-devel \
- libsamplerate-devel pipewire-jack-audio-connection-kit-devel \
-
- NOTES:
- - This includes all the audio targets except arts and esd, because Ubuntu
- (and/or Debian) pulled their packages, but in theory SDL still supports them.
- The sndio audio target is also unavailable on Fedora.
- - libsamplerate0-dev lets SDL optionally link to libresamplerate at runtime
- for higher-quality audio resampling. SDL will work without it if the library
- is missing, so it's safe to build in support even if the end user doesn't
- have this library installed.
- - DirectFB isn't included because the configure script (currently) fails to find
- it at all. You can do "sudo apt-get install libdirectfb-dev" and fix the
- configure script to include DirectFB support. Send patches. :)

- 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"
