You seem to be declaring like this
svn_stream_t resourceStream;
You should declare it as a pointer, like this:
svn_stream_t *resourceStream;

That's what we call an opaque type (or incomplete type). You can create
pointersto the struct, but no instance of the struct itself. It lets us
change te struct without worrying about binary compatibility.
