企业官网建设流程全解析

1. 下载Geant4 source code Download Geant4-11.4.2 - Geant4

2. 安装wsl2 + ubuntu 20.04 下载与安装How to Install WSL2 on Windows 11 (Windows Subsystem for Linux) (2026)

ps. 注意CPU开启虚拟化（BIOS中设置），Linux设置中将网络设置为镜像

3. 新建用户，设置密码

4. 安装 gcc / g++ / cmake / git 等依赖

sudo apt update sudo apt install build-essential cmake git sudo apt install -y libexpat1-dev sudo apt unzip

5. 解压缩与编译Building and Installing from Source — Geant4 Installation Guide 11.2 documentation

mkdir -p ~/geant4 cp /path/to/geant4-v11.4.2.zip ~/geant4/ cd ~/geant4 unzip geant4-v11.4.2.zip rm ~/geant4/geant4-v11.4.2.zip mkdir -p ~/geant4/geant4-v11.4.2-build mkdir -p ~/geant4/geant4-v11.4.2-install cmake -DGEANT4_INSTALL_DATA=ON -DCMAKE_INSTALL_PREFIX=../geant4-v11.4.2-install ../geant4-v11.4.2 cd ~/geant4/geant4-v11.4.2-build make -j12 make install

6. 环境配置，在~/.bashrc中写入

source ~/geant4/geant4-v11.4.2-install/bin/geant4.sh

检查 geant4-config --version

8. 安装Qt等可视化

sudo apt install -y qt6-base-dev libxerces-c-dev libxmu-dev libxkbcommon-dev cmake-curses-gui ccmake ~/geant4/geant4-v11.4.2

打开GEANT4_USE_QT，GEANT4_USE_OPENGL_X11，GEANT4_USE_GDML，以及GEANT4_USE_RAYTRACER_X11，GEANT4_USE_SYSTEM_EXPAT

然后重新编译一下

cd ~/geant4/geant4-v11.4.2-build make -j12 make install

9. 编译案例

cd ~/geant4/geant4-v11.4.2/examples/basic/B1 mkdir -p build cd build cmake .. make -j12 MESA_D3D12_DEFAULT_ADAPTER_NAME=NVIDIA ./exampleB1

注意一定要检查一下自己笔记本/电脑有几张显卡（是不是集显+独显），使用glxinfo -B看一下用的是哪一张。如果用的Intel集成显卡可能会出现Geant4可视化崩溃，也就是D3D12: Removing Device. Segmentation fault (core dumped)。

将export MESA_D3D12_DEFAULT_ADAPTER_NAME=NVIDIA 写进~/.bashrc中然后source ~/.bashrc。再运行./exampleB1看看可不可以了。
