Error when building SampleEnclave in cosmix docker

[CAPTAIN320]

Hello!
I have successfully built Cosmix on the computer, however when I get the following error in cosmix docker when I try to build the SampleEnclave in sgxsdk_samples.
Please help!

Hey,

In the current prototype CoSMIX needs to know the libOS/SDK type used. If using SGX SDK it needs to be built with make SDK_BUILD=-DSDK_BUILD (both cosmix pass, runtime and mstores directories). Can you try recompiling CoSMIX inside the docker with this SGX SDK flag before compiling the SampleEnclave? That should fix the compilation issues.

Thank you very much for your reply.
I am using SGX sdk, and your suggestion successfully built the SampleEnclave.
Thank you.

However, when I try to run the app using ./app, the following error comes up.

It looks like it fails to find the SGX SDK libraries. Setting LD_LIBRARY_PATH to the location where you installed the SGX SDK libs should work. If I recall the SDK also includes an environment script that if invoked sets all the expected SDK environment variables including this one.
