4By default SDL will only link against glibc, the rest of the features will be
5enabled dynamically at runtime depending on the available features on the target
6system. So, for example if you built SDL with XRandR support and the target
7system does not have the XRandR libraries installed, it will be disabled
8at runtime, and you won't get a missing library error, at least with the
9default configuration parameters.

41 should want to use anyhow).

52Joystick does not work
53--------------------------------------------------------------------------------
54
55If you compiled or are using a version of SDL with udev support (and you should!)
56there's a few issues that may cause SDL to fail to detect your joystick. To
57debug this, start by installing the evtest utility. On Ubuntu/Debian:
58
59 sudo apt-get install evtest
60
61Then run:
62
63 sudo evtest
64
65You'll hopefully see your joystick listed along with a name like "/dev/input/eventXX"
66Now run:
67
68 cat /dev/input/event/XX
69
70If you get a permission error, you need to set a udev rule to change the mode of
71your device (see below)
72
73Also, try:
74
75 sudo udevadm info --query=all --name=input/eventXX
76
77If you see a line stating ID_INPUT_JOYSTICK=1, great, if you don't see it,
78you need to set up an udev rule to force this variable.
79
80A combined rule for the Saitek Pro Flight Rudder Pedals to fix both issues looks
81like:
82
83 SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
84 SUBSYSTEM=="input", ATTRS{idProduct}=="0764", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
85
86You can set up similar rules for your device by changing the values listed in
87idProduct and idVendor. To obtain these values, try:
88
89 sudo udevadm info -a --name=input/eventXX | grep idVendor
90 sudo udevadm info -a --name=input/eventXX | grep idProduct
91
92If multiple values come up for each of these, the one you want is the first one of each.
93
94On other systems which ship with an older udev (such as CentOS), you may need
95to set up a rule such as:
96
97 SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1"
