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.
Bash example
This directory contains an example for running Bash in Graphene, including the Makefile and a template for generating the manifest. The application is tested on Ubuntu 16.04, with both normal Linux and SGX platforms.
Generating the manifest
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.
Running Bash with Graphene
Here's an example of running Bash scripts under Graphene:
Without SGX:
./pal_loader bash.manifest -c "ls"
./pal_loader bash.manifest -c "cd scripts && bash bash_test.sh 2"
With SGX:
SGX=1 ./pal_loader bash.manifest -c "ls"
SGX=1 ./pal_loader bash.manifest -c "cd scripts && bash bash_test.sh 2"
