Intel SGX Pthreads

PYuhala — Tue, 24 Nov 2020 10:04:28 GMT

Hello,

The latest Intel SGX developer Reference for Linux* OS (version 2.12) specifies (from page 137) APIs provided by the SGX pthread library. However there is not any example Sample code that uses or shows how to use these APIs in SGX applications. More specifically, what are the associated header files to import, EDL files etc.

I have tried using the API (pthread_create(...) etc) after adding "-lsgx_pthread" in my link options, but this alone does not seem to be enough; the said routines are not found by my compiler.

Hello PYuhala,

In addition to adding -lsgx_pthread to your link statement in the Makefile, you must...

Copy sgxsdk/include/sgx_pthread.edl to your Enclave source directory.
In Enclave.edl, add: from "sgx_pthread.edl" import *;
In Enclave.cpp, add: #include "pthread.h"
