title: Intel SGX remote attestation sample code
body: <p>I'm trying to run the remote attestation sample code in the Intel SGX SDK. I always get error "Error, call sgx_ra_get_msg1 fail [wmain]." I think it's because that the <code>sgx_ra_init(&amp;g_sp_pub_key, b_pse, p_context)</code> function returns a zero value <code>p_context</code>, which can't be used.</p>
  
  <p>Is there anyone can run the remote attestation sample code correctly? 
  PS：I can run the local attestation sample code, I think the Intel SGX development environment is OK.</p>
