The error is precisely what the error message told you: the field called
id, in the struct called kb_event_map_s, has incomplete type. Variable-
length arrays are valid only in C99, and you're probably using a C89
compiler, so you can't do this. You must give id some specific size. If
you need a variable-length array, you can either find a C99 compiler, or
make id a pointer and use malloc().
