DCAP driver needs FLC. Please ensure u have this when running "cpuid | grep -i sgx":
SGX_LC: SGX launch config supported = true

@haitaohuang It seems that my cpu does not support it.

Ok lets forget about DCAP drivers. Even when I install isgx the problem is that I can not run SampleCode applications. It says that there is no sgx device, make sure to enable SGX in Bios and then install sgx-driver. The problem is that I have the isgx driver and in my BIOS I have enabled SGX so do not know why this problem is still happening. I have another computer with the same cpu and processor and in this other computer works ok. The only thing which comes in my mind that what may be wronng is the kernel version: I have 5.4 kernel version. In the other computer where SampleCodes are executed I have 5.0.3 kernel. Is there a problem with this kernel? I tried to find Intel patches for this kernel but could not find them.

it could be the kernel. We only test and support limited versions of distro/kernel combinations for isgx. See README in that repo.
