2.30 Fails to Compile due to 'struct rand_meth_st'

In a Mac app, I updated my dependency from 2.26.0 to 2.30.0 and encountered this:

Is there some build setting that'll resolve this? Rolling back to 2.26.0 resolved it for me. I didn't test intermediary releases.

This looks very odd: it seems like you might have two copies of the headers? Or else you’re finding a conflicting definition elsewhere. Do you have the full textual error? It should show you where the other definition was.
