carlomt/alghero-geant4 repository overview

⁠docker-alghero

you can download these containers with:

docker pull carlomt/alghero-geant4:latest

⁠Compose

To simplify the use of these images we developed a Docker Compose file, to use it donwload it to a folder from https://raw.githubusercontent.com/carlomt/docker-alghero/main/docker-compose.yml⁠

in the same folder, download one of the following files accordingly to your operating system https://raw.githubusercontent.com/carlomt/docker-alghero/main/env_linux⁠ https://raw.githubusercontent.com/carlomt/docker-alghero/main/env_windows⁠ https://raw.githubusercontent.com/carlomt/docker-alghero/main/env_mac⁠ and rename it .env

run:

docker compose run prepare

it will create the subfolders, download the Geant4 datasets and source code. Once it has finished, you can run the Geant4 container:

docker compose run geant4

⁠GUI

To have the graphic user interface you should prepare your operating system host

⁠Linux

Add local connections to X11 access control list:

xhost local:root

such a command has to be executed every time you reboot your computer

⁠Windows

If you don't have X11 already installed (it should be on the latest versions of Windows 11), download XMing from

https://sourceforge.net/projects/xming/⁠

use the Powershell terminal to launch docker compose

⁠Mac

Install XQuartz

https://www.xquartz.org/⁠

start XQuartz:

open -a XQuartz

go to XQuartz->Settings and in the Security panel enable Allow connections from network clients

restart XQuartz:

Check where the XQuartz config file, or domain, is located with:

quartz-wm --help

which should output:

usage: quartz-wm OPTIONS
Aqua window manager for X11.

--version                 Print the version string
--prefs-domain <domain>   Change the domain used for reading preferences
                          (default: org.xquartz.X11

The last line shows the default domain, in this case org.xquartz.X11. Before XQuartz 2.8.0 the default domain was: org.macosforge.xquartz.X11. You can check the default domain with:

defaults read org.xquartz.X11

To have GLX acceleration you must enable it with:

defaults write org.xquartz.X11 enable_iglx -bool true

restart XQuartz again. You can check if GLX is now enabled again with:

defaults read org.xquartz.X11

Finally, you have to allow X11 forwarding to local containers:

xhost +localhost

the latter command has to be executed every time XQuartz is restarted.
