A Sample C++ Project with Makefile and CMake

This project demonstrates how to use Makefile/CMake to build C++ projects for Occlum.

1. Build hello_world with Makefile

make

Or you can build hello_world with CMake

mkdir build && cd build
cmake ../ -DCMAKE_CXX_COMPILER=occlum-g++
make
cd ..
cp build/hello_world .

Either way, the resulting hello_world can be found in the current directory.

2. (Optional) Run hello_world on Linux

./hello_world

3. Run hello_world on Occlum

mkdir occlum_workspace && cd occlum_workspace
occlum init && rm -rf image
copy_bom -f ../hello.yaml --root image --include-dir /opt/occlum/etc/template
occlum build
occlum run /bin/hello_world
