[ocaml-ctypes] ctypes oasis

[Florian Pichlmeier]

Hi,

i am still writing on my small zeromq binding, and thanks to your contributions it grows, but
i still have problems with runtime exceptions like this one

Fatal error: exception Dl.DL_error("./bin-client: undefined symbol: zauth_new")

I was wondering if the reason for this problem lies with in my oasis file

  CCLib:      -lsodium -lczmq -lzmq
  DllLib:     -lczmq_stubs

I have added the no-as-needed part to it but it still doesnt work. 

Is there an obvious mistake in my oasis file?

Best regards,

Florian
