Cannot run client on linux -8th gen i7 processor

[nikhilpopli4900]

This system does not support Intel SGX.
Even though I have SGX_SDK installed and have other applications running smoothly. This gives out the following error.

I got the same message when I run ./run-client, and I have confirmed that other applications for SGX can be run. (e.g. SampleEnclave, LocalAttestation, etc.) Can you please help me if you know the solution?

I have the same issue with an Intel i5-7600.

$ ./run-client
This system does not support Intel SGX.

Solved it by installing libsgx-uae-service.
