+<P>
+wvkbd (Wayland Virtual Keyboard) is a software keyboard implementation for
+environments without a physical keyboard, such as a smartphone or tablet.
+_ref(`#x#sxmo') uses wvkbd by default in its variant for Wayland.
+</P>
+<P>
+wvkbd depends on _ref(`#x#cairo'), _ref(`#fonts#pango'), the Wayland client libraries, and xkb-common.
+</P>
+_subsubheader(`warning: implicit declaration of function `'zwp_virtual_keyboard_*`'')
+<P>
+Due to how the Makefile and ref(`#posix#make(1)') work, if compilation is
+attempted before _program(`wayland-scanner') is installed, an empty
+_file(`proto/virtual-keyboard-unstable-v1-client-protocol.h') will be generated.
+The preprocessor won't error for lack of the file but because the file will be
+empty the necessary prototypes and constants will be missing and compilation
+will fail.
+</P>
+<P>
+_code(`make clean') should fix this.
+</P>
