regarding the following piece of code

      socklen_t sourceAddressLength = sizeof(struct sockaddr_in);
      * messageToReceiveLength = recvfrom(localSocketFd,
                                          messageToReceive,

                                          0,
                                          (struct sockaddr *)
&sourceAddress,
                                          &sourceAddressLength);

I also tried "socklen_t sourceAddressLength =
static_cast<socklen_t> (sizeof(struct sockaddr_in));", but I
get the same errors.

I can't reproduce it on my maching, but a priori, from the
error message, you have a problem with the definition of
socklen_t (which is required by Posix to be an integer type with
at least 32 bits). My guess is that somewhere locally there is
a definition of socklen_t, to something different from what it
is defined as in the Posix header.
