I'm building zeromq library for iOS using this method: https://github.com/drewcrawford/libzmq-ios
The build log looks fine except of some warnings that appear 3 times:

When I add builded library to my XCode project, it generate 10 errors:

ld: symbol(s) not found for architecture i386

I think that every function, which was listed in errors, uses randombytes, which was listed in warning.
The same happens when I add library from https://github.com/drewcrawford/libzmq-ios/releases
What I'm doing wrong?
