1，安装Geant4需求环境

(1,)安装xcode，在~/.bash_profile中添加其环境变量

export PATH="/Applications/CMake.app/Contents/bin":"$PATH"

(2,)brew install clhep

(3,)brew install cmake

(4,)brew install qt5

(5,)brew install xerces-c

2，配置qt5环境变量

在~/.bash_profile中添加如下几行

export PATH="/usr/local/opt/qt@5/bin:$PATH"

 export LDFLAGS="-L/usr/local/opt/qt@5/lib":$LDFLAGS

 export CPPFLAGS="-I/usr/local/opt/qt@5/include":$CPPFLAGS

 export PKG_CONFIG_PATH="/usr/local/opt/qt@5/lib/pkgconfig":$PKG_CONFIG_PATH

3，下载Geant4源码并解压

4，新建build及install文件夹，build及install文件夹与源码文件夹在同一目录层次

5，cd 到build文件夹，运行如下命令：

cmake -DCMAKE_INSTALL_PREFIX=/Users/***/geant4/geant4.10.07_install -DCMAKE_BUILD_TYPE=RelWithDebInfo -DGEANT4_USE_GDML=ON -DGEANT4_BUILD_MULTITHREADED=ON -DXERCESC_ROOT_DIR=/user/local/opt/xerces-c/ -DGEANT4_USE_QT=ON -DGEANT4_INSTALL_EXAMPLES=ON -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_SYSTEM_EXPAT=OFF -DGEANT4_BUILD_TLS_MODEL=auto ../geant4.10.07

6，再运行如下命令：

cmake --build . --target install -- -j8

7，sourc geant4安装目录bin下的geant4.sh

8，编译例子，并执行
