Problem running with SGX

[WHMHammer]

The Run with SGX page says "use the command python3.6 runserver.py --sgx [true]," which doesn't work, and shows:

usage: runserver.py [-h] [-w WORKING_DIR] [-c FUNCTION_CMD]
                    [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}]
                    [host] [port]
runserver.py: error: unrecognized arguments: --sgx

The documentation from the repo says "use the command ./runserver.py -c 'graphene-sgx/pal_loader graphene-sgx/manifest'," which successfully starts the server. However, when I run test_hello_world, it shows the following error:

Exception in thread Thread-1:

FileNotFoundError: [Errno 2] No such file or directory: 'graphene-sgx/pal_loader': 'graphene-sgx/pal_loader'

I found that bento/bento/server/graphene-sgx/pal_loader is a symbolic link to /home/vanilla/sgx/graphene/Runtime/pal_loader, so I changed it to a symbolic link to graphene/Runtime/pal_loader, where graphene is the cloned graphene repo. I started the server and run test_hello_world again. This time it shows the following error:

ERROR:  (29c5c548-5876-41ad-bcf7-c05b246b13ef) Execution error:
 Running from repository is broken. Please install Graphene using Meson.
See https://graphene.readthedocs.io/en/latest/building.html for details.

DEBUG:  (29c5c548-5876-41ad-bcf7-c05b246b13ef) function dead
ERROR:  failed to recv header

I followed all the instructions in the quickstart of the graphene documentation when installing it, and the build was successful. How shall I solve the problem and run bento with SGX support? Thank you.

The error is from Graphene-SGX not bento --- if you open up the pal_loader file, you can see that there is a part where they use INT_GIT to detect whether you are using Graphene the way they wanted. You can try to comment out that part and try again
