Hm this error indicates that the created enclave cannot be found in the process address space. Possible causes could be:

  • Are you running in SGX hardware mode and didn't change the Makefiles to run in simulation mode or so?
  • Are you using one of the supported drivers /dev/isgx or /dev/sgx_enclave?

If the error persists, could you please post the debug output of virtual address space layout, by enabling this line?

I did nothing , I didn't change the Makefile, I follow the installation instructions step by step，then the error happen

Hi Homyee,

Thanks for following up with the extra info. This turned out to be a bug in the /proc/self/maps scanf parsing, good catch!

The commit above should fix this now (at least the parsing works correctly on my system with the layout you provided above).

Let me know if this fixes it for you? And if not, feel free to re-open the issue!

Hope it helps!
