Extend Makefile.configs and define several variables for make to use derived from 'gcc -dumpmachine'. In particular: - ARCH as the architecture, e.g., x86_64 - ARCH_LONG as the long version of the architecture, e.g., x86_64-linux-gnu - ARCH_LIBDIR as the directory where libraries are located, e.g., /lib/x86_64-linux-gnu In Makefiles and manifest templates, replace the hard-coded x86_64-linux_gnu and /lib/x86_64-linux-gnu through these variables. Extend the already existing sed scripts to replace the necessary variables.
Python example
This directory contains an example for running Python 3 in Graphene, including the Makefile and a template for generating the manifest. The application is tested on Ubuntu 16.04 and Ubuntu 18.04, with both normal Linux and SGX platforms. The tested versions of Python are 3.5 and 3.6.
Generating the manifest
Installing prerequisites
For generating the manifest and running the test scripts, please run the following command to install the required utility packages (Ubuntu-specific):
sudo apt-get install libnss-mdns
Building for Linux
Run make (non-debug) or make DEBUG=1 (debug) in the directory.
Building for SGX
Run make SGX=1 (non-debug) or make SGX=1 DEBUG=1 (debug) in the directory.
Building with a local Python installation
By default, the make command creates the manifest for the Python binary from
the system installation. If you have a local installation, you may create the
manifest with the PYTHONPATH variable set accordingly. You can also specify
a particular version of Python. For example:
make PYTHONPATH=<python install path> PYTHONVERSION=python3.6 SGX=1
By default, PYTHONPATH=/usr and PYTHONVERSION=python3.5.
Run Python with Graphene
Here's an example of running Python scripts under Graphene:
Without SGX:
./pal_loader python.manifest scripts/helloworld.py
./pal_loader python.manifest scripts/fibonacci.py
With SGX:
SGX=1 ./pal_loader python.manifest scripts/helloworld.py
SGX=1 ./pal_loader python.manifest scripts/fibonacci.py
You can also manually run included tests:
SGX=1 ./run-tests.sh
