change zeromq version to 4.0.2, same error but another symbol (_zmq_ctx_term).

install zeromq(4.2.2) from source manually, "Symbol not found" is gone, but too many test case failed.

same error: "NameError: undefined local variable or method `rc' for #"

This is very odd.

With zeromq 4.2.2 installed I get the _randombytes error. I reinstalled brew install zeromq --with-libsodium and that solves that linking issue. However, now it complains about missing _zmq_ctx_term. Running nm -gU /path/to/libzmq.dylib clearly shows that symbol is exported and available.

This is a head scratcher... will work on it.

Fixed in release 2.0.5 (and in ffi-rzmq-core release 1.0.6).

Thank you for the report.

janckerchen commented 7 years ago

maybe something wrong in homebrew. I tried another zmq binding and encontered same error.

Maybe macOS Sierra update cause this?

chuckremes commented 7 years ago

@janckerchen I think it might be a problem with the default home-brew formula which does NOT build zeromq with libsodium support. Try brew install zeromq --with-libsodium and try again.
