SGX SDK Sample Code for CentOS -- needs protobuf

glenn_t_ — Fri, 06 Jul 2018 14:38:09 GMT

I purchased a NUC with SGX SDK installed. I ran the centOS command "yum update" and the machine locked up. It would not reboot. I installed centOS 7.5 and downloaded the SGX SDK from the Intel website. The sample code projects will compile but not run. The runtime library libprotobuf 8 is not part of the "Development Tools" group for Centos 7.5 -- the SDK is targeted for CentOS 7.4 but I can no longer find a 7.4 download.

My questions are these (any answers is appreciated) :

Is protobuf only used for these examples (why use it at all) or is it part of the SGX SDK?

Is does anyone know where i can get an rpm for protobuf 8 -- I've seen other versions but only 8 will work?

How do I modify the code to no longer depend on this library?

Has anyone had a problem with updating this NUC with CentOS since 7.5 was released?

Thanks in advance

Hi glenn,

The Rust SGX SDK supports protobuf in both HW and SW mode. The code sample is here at https://github.com/baidu/rust-sgx-sdk/tree/master/samplecode/protobuf

Thanks for your reply and I will keep that in mind. We have ordered another SGX SDK NUC unit and that information may be useful in the future.

In the mean time I have reloaded with Ubuntu 16.04 and reloaded the SDK and the sample code builds fine. I have run some of the examples.
