I'm not quite sure why you're trying to link this as a shared library. XI is
mandatory these days so you're moving something into a shared library that
can only be used by the server and is always used anyway.

CoreKeyboardProc and the other symbols you're missing have the attribute of
_X_HIDDEN so they wouldn't be visible ot the shared library. you could
change that to _X_EXPORT or just change the visibility gcc args. But then
again, I'm not sure trying to make parts of the X server a shared library is
going to be very useful.
