[GitHub] [incubator-teaclave-sgx-sdk] shixiongjing opened a new issue #202:
Some questions about sample code
shixiongjing opened a new issue #202: Some questions about sample code
URL: https://github.com/apache/incubator-teaclave-sgx-sdk/issues/202
Hi, I am new to the project, and have never used Rust before. I am sorry that this question might be naive.
I just tried to cloned the repo and followed the guide "Use simulation mode for non SGX-enabled machine (includes macOS)" in the readme to run the helloworld example in software mode. But I got several errors during 'make'. The exact errors actually seem straight forward, but I am worried that I got something wrong in the environment, because that was the example from the tutorial and it was expected to run without problems if I did everything right.
I am running docker on ubuntu 18.04 (tried both docker image 'latest' and 1804:1.0.7), and I have changed the sgx_mode in Makefile to SW. The errors are attached. Any idea on what I did wrong? Please help. Any suggestion is appreciated!

You are right. I tried nightly when I tried running outside docker earlier and I forgot to switch to nightly in docker...Thanks a lot.
