| 14 | System Requirements:
|
|---|
| 15 | -------------------
|
|---|
| 16 | Python
|
|---|
| 17 | - only 2.x is tested.
|
|---|
| 18 |
|
|---|
| 19 | Geant4
|
|---|
| 20 | - 8.0 or later
|
|---|
| 21 | - should be built in "GLOBAL" and "SHARED" libraries.
|
|---|
| 22 | - All header files should be collected into $(G4INSTALL)/include
|
|---|
| 23 | by "make includes"
|
|---|
| 24 |
|
|---|
| 25 | CLHEP
|
|---|
| 26 | - 1.9.1.1 or later
|
|---|
| 27 | - should be built in shared library.
|
|---|
| 28 | - Building shared objects is supported since version 1.9.
|
|---|
| 29 |
|
|---|
| 30 | (Optional)
|
|---|
| 31 | ROOT
|
|---|
| 32 |
|
|---|
| 33 | Before Starting:
|
|---|
| 34 | ----------------
|
|---|
| 35 | In dafault situation, Geant4 creates and uses "granular static libraries".
|
|---|
| 36 | But, the Python interface requires "GLOBAL SHARED library".
|
|---|
| 37 | If you donot build your Geant4 libraries in global shared mode,
|
|---|
| 38 | you have to recreate your instance additionally.
|
|---|
| 39 |
|
|---|
| 40 | In "tools" directory, you can find some ways to handle both "glanular static"
|
|---|
| 41 | and "global shared" environments. Please take a look.
|
|---|
| 42 |
|
|---|
| 43 |
|
|---|
| 44 | How to Install:
|
|---|
| 45 | ---------------
|
|---|
| 46 | There is a configuraton script for building the package.
|
|---|
| 47 |
|
|---|
| 48 | # ./configure --help
|
|---|
| 49 | `configure' configures Geant4Py to adapt to many kinds of systems.
|
|---|
| 50 |
|
|---|
| 51 | Usage: ./configure SYSTEM [OPTION]... [VAR=VALUE]...
|
|---|
| 52 |
|
|---|
| 53 | SYSTEM: System type (see Supported Arhitectures)
|
|---|
| 54 |
|
|---|
| 55 | Options:
|
|---|
| 56 | -h, --help Display this help and exit
|
|---|
| 57 |
|
|---|
| 58 | Installation directories:
|
|---|
| 59 | --prefix=PREFIX Installation prefix [./]
|
|---|
| 60 | --libdir=DIR Python modules dir [PREFIX/lib]
|
|---|
| 61 |
|
|---|

|
|---|
| 70 | (location of pyconfig.h)
|
|---|

|
|---|
| 74 | (location of boost/)
|
|---|
| 75 | --with-boost-libdir=DIR BOOST-C++ library dir [/usr/lib]
|
|---|
| 76 | --with-boost-python-lib=LIB library name of libboost_python.so [boost_python]

|---|
| 77 |
|
|---|
| 78 | --with-package-dir=DIR Geant4 Package dir
|
|---|
| 79 |
|
|---|
| 80 | --with-extra-dir=DIR Install path for extra packages [/usr/local]
|
|---|
| 81 |
|
|---|
| 82 | --with-xercesc-incdir=DIR Xerces-C header dir [/usr/include]
|
|---|
| 83 | --with-xercesc-libdir=DIR Xerces-C library dir [/usr/lib(64)]
|
|---|
| 84 |
|
|---|
| 85 | Enable/disable options: prefix with either --enable- or --disable-
|
|---|

|
|---|
| 88 | raytracerx RayTracerX support [disable, $G4VIS_USE_RAYTRACERX]
|
|---|
| 89 |
|
|---|
| 90 | Supported Architectures:
|
|---|
| 91 | linux for Linux gcc 3.x and 4.x (32bit)
|
|---|
| 92 | linux64 for Linux gcc 3.x and 4.x (64bit, alias to linuxx8664gcc)
|
|---|
| 93 | linuxx8664gcc for AMD Opteron and Intel EM64T Linux gcc 3.x and 4.x
|
|---|
| 94 | macosx for MacOSX with gcc (Tiger/Leopard and Xcode)
|
|---|
| 95 |
|
|---|
| 96 | You can specify all parameters adopting your environment.
|
|---|
| 97 |
|
|---|
| 98 | For example,
|
|---|
| 99 | # ./configure linux64 (miserable)
|
|---|
| 100 | --with-g4-incdir=/opt/heplib/Geant4/geant4.8.1/include
|
|---|
| 101 | --with-g4-libdir=/opt/heplib/Geant4/geant4.8.1/slib/Linux-g++
|
|---|
| 102 | --with-clhep-incdir=/opt/heplib/CLHEP/2.0.2.2/include
|
|---|
| 103 | --with-clhep-libdir=/opt/heplib/CLHEP/2.0.2.2/lib
|
|---|
| 104 | --with-clhep-lib=CLHEP-2.0.2.2
|
|---|
| 105 |
|
|---|
| 106 | # ./configure linux64 (smart)
|
|---|
| 107 | --with-package-dir=/opt/heplib/Geant4/packages/9.1.2
|
|---|
| 108 |
|
|---|
| 109 | # ./confugre linux64 (intelligent or haphazard ?)
|
|---|
| 110 |
|
|---|
| 111 | The configuration script will create config/config.gmk, which describes
|
|---|
| 112 | your envrionment.
|
|---|
| 113 |
|
|---|
| 114 | After executing the configure script, then
|
|---|
| 115 |
|
|---|
| 116 | # make
|
|---|
| 117 | # make install
|
|---|
| 118 |
|
|---|
| 119 | That's all!
|
|---|
| 120 |
|
|---|
| 121 | How to Use:
|
|---|
| 122 | -----------
|
|---|
| 123 | Some environment variables are required at run time.
|
|---|
| 124 |
|
|---|
| 125 | * PYTHONPATH
|
|---|
| 126 | Python module search directories, given by a colon-separated list
|
|---|
| 127 | of directories.
|
|---|
| 128 | Practically, $(INSTALL_PATH)/lib is ok.
|
|---|
| 129 |
|
|---|
| 130 | * LD_LIBRARY_PATH
|
|---|
| 131 | Additional shared library path to be searched.
|
|---|
| 132 |
|
|---|
| 133 | Some libraries paths are already specified via "-rpath" linker option,
|
|---|
| 134 | so these paths do not have to be added to "LD_LIBRARY_PATH".
|
|---|
| 135 | * Geant4
|
|---|
| 136 | * CLHEP
|
|---|
| 137 | * boost-python library
|
|---|
| 138 | * $(INSTALL_PATH)/lib
|
|---|
| 139 | * $(G4PY_EXLIB_LIBDIR) specified in a module makefile.
|
|---|
| 140 |
|
|---|
| 141 |
|
|---|
| 142 | You can import Geant4Py modules in Python just like
|
|---|
| 143 |
|
|---|
| 144 | >>> import Geant4
|
|---|
| 145 |
|
|---|
| 146 | Notes:
|
|---|
| 147 | -----
|
|---|
| 148 | 1) >> IMPORTANT <<
|
|---|
| 149 | All users' libraries should be build in SHARED libaries.
|
|---|
