The repository is part of the Compiler Explorer project. It builds the docker images used to build the d8 runtime/compiler/tooling used on the site.
You need to have docker installed on your machine. If you do not have docker installed you can get it from here
After doing this, run the following command in the root directory of this repository:
docker build -t d8:trunk .
This will create a container in your machine named d8:trunk
You can check if the container has been built by running the following command:
docker images
You should see the image listed as follows:
REPOSITORY TAG IMAGE ID CREATED SIZE
d8 trunk fcd7f69f0e42 3 weeks ago 8.31GB
Once you have this, you can start a shell with this image using the following command.
docker run --rm -it d8:trunk bash
You can then build the d8 executable inside the container by running the following commands
cd /root/v8
python ./tools/dev/gm.py x64.release
After this you will see that the d8 executale is present in /root/v8/out/x64.release
You can then start a d8 shell by running the following command
cd /root/v8/out/x64.release
./d8
To get the latest version of v8 you can list the branches that start with branch-heads. You can use this command to get the latest version:
git branch -a | grep remotes/branch-heads | awk -F/ '{print $NF}' \
| sort -t. -k1,1nr -k2,2nr -k3,3nr | head -n1
