Cernlib, Paw on MacOS



Here is a quick way to run cernlib’s paw in a Docker container on MacOS1. This uses a debian based container with paw, paw++, and cernlib installed via the system (i.e. apt-get).

Requirements

Install the Docker and X11 (XQuartz) apps:

After installing XQuartz, make sure to enable “Allow connections from network clients” in the Preferences > Security tab. It should look like this:

xquarts security preferences

Allow connections from network clients. You may need to restart XQuartz for the change to take effect.

Run the following command in a terminal to allow X11 connections from Docker containers:

xhost +

Running Paw/Cernlib in Docker

In the following instructions we assume you are using a Mac with a silicon CPU (M1/M2/M3, etc). If you have an Intel CPU, remove the --platform linux/amd64 option from the docker run command below.

In a terminal, run the following commands to create a script dsh that will launch an interactive shell in the container:

docker pull jeffersonlab/cernlib:2004
docker run --rm -it --platform linux/amd64 jeffersonlab/cernlib:2004 cat /container/image/dsh | tr -d "\r" > dsh
chmod +x dsh

You’re now ready to run Paw/Cernlib in Docker. In a terminal, run the following command to launch an interactive shell in the container, and then start paw++:

./dsh jeffersonlab/cernlib:2004
paw++
