local LA migration "Error sending message! Bad file descriptor"

Hi,

I am getting the same error as https://github.com/SSGAalto/sgx-migration/issues/2. Did you happen to find any solution? Which boost version should I use?

Do you get exactly the same error in marshalling.cpp ? Or a different error based on boost? When trying to compile, I now get the error that io_service does not exist. Apparently the io_service was removed in Boost 1.7: https://www.boost.org/doc/libs/1_70_0/doc/html/boost_asio/history.html

Either you use boost before 1.7 or you update the TcpServer.cpp to use the current boost alternatives. I do not really have time to make this project work again but I am happy to accept Pull requests or discuss issues.

I tried with boost 1.58

Error returns from send_message_read_response function. Which originate from network_common.cpp --> TcpConnection.cpp at following call int len = boost::asio::write(socket_, boost::asio::buffer(out_buf), boost::asio::transfer_all() , error);

I understand your busyness. However, any small hint or guidance will be helpful.
