Installation of Geant4.9.4 on Ubuntu10.10 or Ubuntu10.04

2011-02-11

Install Ubuntu10.10 on VBox.

The installation lasted from 8:14PM to 8:44 PM.

2011-02-12

Set password for root account

In a terminal, type:

sudo passwd root

and then you can set a password for root user.

Now I want to build the Geant4 thoroughly by logging in username account but not root account.

Prerequisites:

1, install the essential compiling environment, otherwise, you can see error: C++ compiler cannot create executables for CLHEP

sudo apt-get install build-essential

2, install OpenGL library

sudo apt-get install libgl1-mesa-dev

3, install OpenGL utilities

sudo apt-get install libglu1-mesa-dev

4, avoid the error: X11/Intrinsic.h: No such file or directory in Geant4 installation.

sudo apt-get install libxt-dev

5, ubuntu software center, search: libxmu, and install all the seven available packages to avoid the error: include/G4OpenGLXViewer.hh; 46:29: error: X11/Xmu/StdCmap.h: No such file or directory.

6, A ubuntu10.10-specialized problem is that geant4 cannot find lXpm, so you have to search libXpm and install libxpm-dev, libxpm4-dbg, and libxpm4.

7, install Xerces C Parser if you want to use gdml in Geant4

Ubuntu software center, search Xerces, and then install:

Validating XML parser library for C++ (development files) (libxerces-c-dev)

And the libxerces-c3.1 will be installed together.

If you prefer libxerces-c2-dev, libxerces-c28 will be installed together.

NOTE: you can install either libxerces-c-dev or libxerces-c2-dev, but not both together.

Actually, I installed libxerces-c2-dev and libxerces-c28. I also installed libxerces-c3.1 manually.

The default location for headers is /usr/include/xercesc; for lib it is /usr/lib, etc.

If you download a full xerces from its website, you can install all the contents in one independent folder, so it will be easy to set the environment variable $XERCESCROOT.

In this software center installation method, we will set $XERCESCROOT=/usr

Put $XERCESCROOT/lib (actually it is /usr/lib) in /etc/ld.so.conf to avoid to see the error information in codeblocks that no $XERCESCROOT is found.

Add

export XERCESCROOT=/usr

in your .bashrc

8, install libXi to avoid the error: /usr/bin/ld cannot find -lXi

Software center, search libxi

And then install libxi6-dbg and libxi-dev and libxiterm1

Finally, you can see /usr/lib/libXi.a and libXi.so.

9, install open inventor driver (not recommended because it will result in incompatible problems with OpenScientist)

Software center search open inventor

Inventor-clients, inventor-doc, inventor-dev, inventor-data, libinventor0

The default location is /usr

10, install qt4

Software center, search libqt4-dev

Install libqt4-dev, and you will find several other useful packages, such as libqt4-opengl-dev, libqt4-designer are also installed together.

The default location is /usr

You can use:

qmake –v

to see the version of qt:

QMake version 2.01a

Using Qt version 4.7.0 in /usr/lib

11, java

Search OpenJDK in software center of Ubuntu and install it.

Add below lines in your .bashrc

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk

export JDK_HOME=$JAVA_HOME

export PATH=$JAVA_HOME/bin:$PATH

#open jdk

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Installation of CLHEP2.1.0.1

Create a folder called G4install in your home directory, i.e.,  /home/username.

Unzip clhep-2.1.0.1.tgz into /home/username/G4install

Cd ~/G4install/2.1.0.1/CLHEP

Here ~ stands for your home directory /home/username

./configure --prefix /home/username/G4install/2.1.0.1

Then you can see the configuration procedure:

Checking build system type… i686-pc-linux-gnu

After a long while, when you see:

config.status: creating Exceptions/defs.h

config.status: executing depfiles commands

everything is OK.

make

When make ends, you can see:

./build-header

make[1]: Leaving directory `/home/username/G4install/2.1.0.1/CLHEP'

then you can install clhep via:

make install

Then you can see lib, include and bin folders are produced in the directory of 2.1.0.1, parallel to the CLHEP folder.

When you install geant4, it will ask you where the clhep is, you should answer:

/home/username/G4install/2.1.0.1

That is correct and enough.

Install Geant4

1, Download geant4.9.4 and data files.

2, Unzip geant4.9.4 in /home/username/G4install and in the geant4.9.4 directory, create a new folder named data and put all 9 data packages there and unzip them.

3, At first, use

printenv | grep G4

to see all the current environment variables containing “G4”.

If you can see them, please try to delete them before installing geant4.

4,

cd G4install/geant4.9.4/

5,

./Configure -build

Creating configuration setup file...

WARNING: the generated configuration file

can be edited if necessary!

You can introduce any change to the configuration file

/home/username/G4install/geant4.9.4/.config/bin/Linux-g++/config.sh before the final installation.

To do so, use a shell escape now (e.g. !vi /home/username/G4install/geant4.9.4/.config/bin/Linux-g++/config.sh).

Press [Enter] to start installation or use a shell escape to edit config.sh:

2:46pm, the build procedure began

3:51pm, the build procedure finished

Libraries installation completed !

If there were errors in your installation, i.e., cannot find lXpm, it will show:

############################################################

# It looks like you had errors during Geant4 installation  

# (or interrupted installation)!                                                    

# Please check log file:                                                                     

# /home/username/G4install/geant4.9.4/.config/bin/Linux-g++/g4make.log                       

############################################################

If everything is OK, you will see:

####################################################

# Your Geant4 installation seems to be successful! 

# To be sure please have a look into the log file: 

# /home/username/G4install/geant4.9.4/.config/bin/Linux-g++/g4make.log                       

####################################################

Only shared, global libraries will be built. i.e. *.so are produced in lib folder of geant4.9.4

If in this option, you choose n,

Enable internal zlib compression for HepRep visualization? [n] n

You will see the fatal error: zib.h: No such file or directory

But, actually, zlib.h is located in the folder /usr/include

If zlib.h really doesn’t exit, you can install it by:

Sudo apt-get install zliblg-dev

6,

./Configure -install

All the necessary headers will be copied into include folder of geant4.9.4

7,

./Configure

env.sh and env.csh are produced in geant4.9.4

8,

create a new folder named G4work in /home/username

9,

in your home directory,

gedit .bashrc

add below three lines:

export G4WORKDIR=$HOME/G4work

export LD_LIBRARY_PATH=$HOME/G4install/2.1.0.1/lib:$LD_LIBRARY_PATH

source $HOME/G4install/geant4.9.4/env.sh

10,

exit and restart a terminal

and you can see the environment variables related with geant4
