Problem in calling sgx_ra_proc_msg2

Hi,I am learning SGX and doing experiment on ubuntu 14.04 and sdk version 1.5.

In remote attestation sample code , the service provider is a dynamic library, isv_app and service_provider are in the same program. I divided the code into two parts and make them connect through socket, but I have a problem in calling sgx_ra_proc_msg2.

When isv_app get msg2 coming from service provider and call sgx_ra_proc_msg2, it always getting NULL msg3. I check it for some time but I can't figure it out.

Please help me.

Hi.

Hi.

Did you check the return code after calling sgx_ra_proc_msg2?

Also, is there a specific reason why you are using SGX SDK v1.5 and Ubuntu 14.04 instead of the currently supported versions (SGX SDK v1.8 and Ubuntu16.04)?
