If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

As said, the best way to run Geant4 is to build from source. I'll try to describe a recipe here...sorry if it's not complete.
1) First of all, in Ubuntu you have to install some dependencies:
->$sudo apt-get install expat* libxerces2-java libxerces-c2-dev libxerces-c3.1 qt-sdk gcc cmake freeglut3 freeglut3-dev binutils-gold x11-common x11-utils xorg xorg-dev
That will take a while too complete.
2) Download the Geant4 code from http://geant4.cern.ch/ and extract it.
3) Rename the folder as 'geant4.9.6', and then create another directory named 'geant4.9.6-build';
4) On the 'geant4.9.6-build' directory run cmake, as follows:
->$cmake -DCMAKE_INSTALL_PREFIX=/path_to/geant4.9.6-install -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_GDML=ON -DGEANT4_USE_QT=ON -DGEANT4_USE_OPENGL_X11=ON /path_to/geant4.9.6
where 'path_to' is your path to the geant4.9.6 directory. I already included some options on the cmake command, so you don't have to download some additional data. If everything went ok, you'll get the following message at the end:
-- Configuring done -- Generating done -- Build files have been written to: /path_to/geant4.9.6-build
5) Run 'make' and then 'make install'
6) That's all. For you to run Geant4 examples and any anything else, you just have to go to '/path_to/geant4.9.6-install/bin' and run
so data will be available to you.
Hope it helps.
