|
|
```sh
|
||
|
|
>mkdir Clarion2_build
|
||
|
|
>cd Clarion2_build
|
||
|
|
>cmake <path/to/CLARION2_GEANT4
|
||
|
|
>make

||
|
|
```

# To build GEANT4 11.2.0 in Ubuntu 22.04
|
||
|
|
|

|
|
## Visuailization
|
||
|
|
|
||

|
|
>sudo apt install qt6-base-dev libqt6charts6-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
the openGL should come with Ubuntu 22.04
