Hmm. This is using a Gnu C extension (variable sized arrays), which isn't
what you intended. At this stage you are declaring a two dimensional array
of pointers, with size x is one direction and y in the other. Since you've
already defined the array (haven't you?), what you meant was probably:

View[x][y] = (defPt *)calloc(1,sizeof(defPt));

I hope this helps.
