Container Building

How to build with Docker

1. First download docker. (link for mac)

2. Clone the repo

3. cd vt

4. Note, the default docker environment variables are in vt/.env

5. Look at comments at the top of vt/docker-compose.yml for environment variables that can be set to configure build. By default, you will get GNU gcc-7, ubuntu 18.04, LB enabled, trace disabled

6. For instance, if you want to turn on trace: export VT_TRACE=1

7. Pull the pre-built image, selected based on environment variables: docker-compose pull ubuntu-cpp

8. Run the image in interactive mode: docker-compose run ubuntu-cpp-interactive

9. In the image run: /vt/ci/build_cpp.sh /vt /build

10. After cmake runs, you can control-c and cd build/vt. From here you can edit, rebuild, etc.
