The documentation currently specifies SGX_SIGNER_KEY as the parameter to enable Graphene to find your keys. Some examples don't use an environment parameter at all for the key to sign the enclave, this commit fixes that.
Introduction
This directory contains a Makefile and template manifests to run gcc and its related tools on Graphene. We tested with gcc version 5.5.0 and binutils (as, ld) version 2.26.1 on Ubuntu 16.04. We also tested on Ubuntu 18.04 with gcc version 7.4.0 and binutils version 2.30. This example uses the package version of gcc and related tools (as, cc1, collect2, ld) installed on the system instead of compiling them from source as some of the other examples do.
The Makefile and the template manifest contain comments to hopefully make them easier to understand.
Quick Start
To run the regression tests execute make check. To do the same for SGX, execute SGX=1 make check. The regression tests build three sample programs - helloworld.c, bzip2.c and gzip.c - and
test their functionality.
By looking at the Makefile "check" target you can see how gcc is invoked to compile individual source files under the hood. If you want to compile different and/or more complex applications, you would likely need to tweak the manifest files to whitelist additional files.
