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
