# Welcome to the HACKER CHALLENGE
|
||||
|
||||
## Building and packaging the challenge
|
||||
|
||||
The host can be without SGX support.
|
||||
To build and package the challenge you will need the docker environment.
|
||||
Do the following steps to build the challenge:
|
||||
|
||||
```bash
|
||||
# Notice that there is no SGX device mounted
|
||||
docker run --rm -it -v /path/to/rewrite:/root/rewrite occlum/occlum:latest-ubuntu20.04
|
||||
# Inside the docker container do env preparation to build the image
|
||||
rustup install stable-x86_64-unknown-linux-gnu
|
||||
rustup default stable
|
||||
rustup target add x86_64-unknown-linux-musl
|
||||
|
||||
cd /root/rewrite && ./scripts/package.sh
|
||||
# Feel free to exit the container once the challenge was packaged
|
||||
exit
|
||||
```
|
||||
|
||||
## Testing the challenge
|
||||
|
||||
To test the challenge you will need the SGX support.
|
||||
|
||||
## Contributing to the challenge
|
||||
|
||||
Don't forget to run `cargo clippy` and `cargo fmt` before submitting a PR.
