Dynamic linker error?

[Aditya Kousik]

I could fix this issue actually. One, I had to increase the quota required
for each service, and I decided to use lwIP over lxip. I just needed the
if_indextoname methods and send() calls, which were in libc-net. I've gone
past all this, but now it's a different kind of problem. The client object
won't create an object of Connection.

client_consumer is the client application that uses my
ndn_session/connection.h interface, and handler is the server side
implementation. I printed some debug statements in main() of client which
calls a run() method. I create a ndn_session::Connection _ndn_session
object and the client freezes at this point. I've put print statements in
the constructor of Session_client (in client.h), and Connection too.
Neither get printed.

Thanks,
Aditya
