# A Sample C++ Project with Bazel This project demonstrates how to use Bazel to build C++ projects for Occlum. To install Bazel on Ubuntu, follow the instructions [here](https://docs.bazel.build/versions/master/install-ubuntu.html). 1. Download a Bazel sample project in C++ and build it with Occlum toolchain ``` ./build_bazel_sample.sh ``` When completed, the resulting `hello-world` can be found in `examples/cpp-tutorial/stage3/bazel-bin/main` directory. 2. (Optional) Run `hello-world` on Linux ``` ./examples/cpp-tutorial/stage3/bazel-bin/main/hello-world ``` 3. Run `hello-world` on Occlum ``` mkdir occlum_workspace && cd occlum_workspace occlum init cp ../examples/cpp-tutorial/stage3/bazel-bin/main/hello-world image/bin occlum build occlum run /bin/hello-world ```
