Missing dependency when running the docker. #4

Closed pegartillo95 closed 4 years ago

pegartillo95 commented 4 years ago

I have just downloaded the repo and followed the steps to execute it using docker provided. After building the docker and executing 

SGX_MODE=SIM make clean && make

to build the attestor in simulation mode.

Then when I try to execute the attestor to generate the file I get the following error message about a missing dependency.

./attestor: error while loading shared libraries: libsgx_uae_service.so: cannot open shared object file: No such file or directory

Thanks @pegartillo95 I could initially reproduce this. I cleaned out the containers and images and rebuilt the image. After that I can't reproduce the error anymore. I wonder if there was some dependency transition that was cached in older images. You could try docker container prune and then docker rmi dancap:latest Then rebuilding and re-running

./build-docker
./run-docker
SGX_MODE=SIM make clean && make
./attestor

Hello: I just realised that the problem is that the command to build in the SIM mode is in the wrong order and it tries to build it on hardware mode. If you execute instead.

make clean && make SGX_MODE=SIM

it works and you can execute the whole process.

P.D: Although now the whole process works and it generates the Quote, when passing that generated quote to the verifier I'm getting the following error that is different to the one you explain on your repo. I am using a Mac in case that makes any difference.

This is the error:

Reading 1116 bytes... Read attestation file successfully.
ERROR: Quote verification FAILED with error: e01d
 Verification error code: a006

The quote generated by the attestor is this one.

@pegartillo95 good catch on the build variable. I've set defaults for the container and updated the docs to fix the variable usage. The error on verification is expected and I've updated the docs for that too. Basically a simulated attestation should fail verification because it's not real. Changes in #5 Thanks
