The manifest syntax stays exactly the same, including 0 and 1 integers to denote boolean values (this is done for ease of porting and can be fixed in future commits). The only visible change is surrounding strings in the manifest with quotes (requirement of TOML). All manifests and Makefiles of our tests and example apps are ported to the new TOML syntax. Documentation is updated.
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.
This example is temporarily broken until we rewrite Graphene loader
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.
