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.

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" + -- cgit v1.2.3
