SGX build dependencies
|
||
|
|
===
|

|
|
|
||
|
|
The aim of this folder is to pin some build dependencies of the SGX work that would otherwise cause reproducibility problems.
|
||
|
|
|
||
|
|
Normally you shouldn't care about this folder, everything should work as long as you use the Makefile in the parent folder.
|
||
|
|
|
||
|
|
The pinned dependencies reside in `root/`.

|
There are two dockerfiles, one in `docker-full` specifying all build dependencies, and one in `docker-minimal`, specifying the minimal system we assume developers have.
|
||
|
|
|
||
|
|
Once we build `docker-full` we can extract the relevant parts of the filesystem using `extract_dependencies.sh`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker build -t full docker-full # builds a Docker image using docker-full/
|
||
|
|
$ bash extract_dependencies.sh full # Extracts some of the filesystem in the `full` image using the list in `extracted_files` into `root/`
|
||
|
|
```
|
||
|
|
|
||
|
|
The SGX build is setup so it refers to the `root/` folder instead of using files coming from system packages.
|
||
|
|
|
||
|
|
Some dependencies are still required to be installed, these are specified in `docker-minimal`. We can use `build_in_docker.sh` to test whether the build works in a minimal dev environment:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker build -t minimal docker-minimal # builds a Docker image using docker-minimal/
|
||
|
|
$ bash build_in_image.sh minimal # Runs the build inside the `minimal` image
|
||
|
|
```
