系统Ubuntu 12.04 32位版，gcc 4.6，Geant 4.9.5p1，CLHEP

2.1.2.2

参考

Installing Geant4 Release 4.9.4.p02 on Linux

http://geant4.slac.stanford.edu/tutorial/installation/Geant4.9.4.p02/Linux/Geant4_9_4_p02_Linux_Installation.htm#_What_are_the

准备编译环境：

sudo apt-get install build-essential cmake

cmake版本2.8.7

1)安装CLHEP

由于新版CLHEP采用cmake方式编译，原教程不适用，参考cmake/INSTALL安装方法如下：

mkdir ~/build

cd ~/build

cmake /home/tyllr/CLHEP/2.1.2.2/CLHEP

make

make test

sudo make install

在/usr/local/lib下得到编译好的多个库，成功！

2)安装Geant4

添加低能电磁作用数据包，data files for low

energyelectromagnetic processes

解压到Geant4目录新建的 data 文件夹下。

tyllr@tyllr-MXC061:~/geant4_9_5_p01$ mkdir ~/geant4build

tyllr@tyllr-MXC061:~/geant4_9_5_p01$ cd ~/geant4build/

tyllr@tyllr-MXC061:~/geant4build$ cmake ../geant4_9_5_p01

-- Build files have been written to: /home/tyllr/geant4build

找不到 EXPAT，尝试：

sudo apt-get install libexpat-dev

cmake ../geant4_9_5_p01

结果如下：

-- setting default compiler flags for CXX

-- Found EXPAT: /usr/lib/i386-linux-gnu/libexpat.so

-- The following Geant4 features are enabled:

GEANT4_USE_SYSTEM_EXPAT: Using system install of EXPAT

tyllr@tyllr-MXC061:~/geant4build$ make

-j2

我是core 2

duo的cpu，所以用双核选项。编译很漫长，喝杯咖啡慢慢等。。。

完成后 sudo make

install，结束安装。

3)测试例子

mkdir ~/g4examplebuild

cd ~/g4examplebuild

cmake ../geant4_9_5_p01/examples/novice

make

运行可执行文件：

tyllr@tyllr-MXC061:~/g4examplebuild$ cd N01

tyllr@tyllr-MXC061:~/g4examplebuild/N01$ ./exampleN01
