Would you like to see the instructions? [n] y
 
This installation shell script will examine your system and ask you questions
to determine how the Geant4 Toolkit should be installed.  If you get stuck on
a question, you may use a ! shell escape to start a subshell or execute a
command.  Many of the questions will have default answers in square brackets;
typing carriage return will set the default.

On AFS it is allowed to specify either absolute or relative
paths (i.e. starting with the ~username construct).

[Type carriage return to continue] 

The prompt used in this script allows you to use shell variables and backticks
in your answers. You may use $1, $2, etc...  to refer to the words in the
default answer, as if the default line was a set of arguments given to a
script shell. This means you may also use $* to repeat the whole default line.

Everytime there is a substitution, you will have to confirm.  If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.

Running 'Configure -d' will bypass nearly all the questions and
use the computed defaults (or answers saved in a configuration
previously generated).

Type 'Configure -h' for a list of options.

You may also start interactively and then answer '& -d' at any prompt to turn
on the non-interactive behaviour for the rest of the execution.

[Type carriage return to continue] 

Much effort has been spent to ensure that this shell script will run on any
Unix system. If despite that you can't run Configure for some reason, you'll
have to set the proper environment variables by hand and follow the "manual"
installation as specified in the Geant4 Installation Guide.

Definition of G4SYSTEM variable is Darwin-g++.
That stands for:

1) OS      : Darwin

2) Compiler   : g++

I can set things up so that your shell scripts and binaries are more portable,
at what may be a noticable cost in performance.  In particular, if you
ask to be portable, the following happens:

     1) Shell scripts will rely on the PATH variable rather than using
   the paths derived above.
     2) ~username interpretations will be done at run time rather than
   by Configure.

Do you expect to run these scripts and binaries on multiple machines? [n]

Creating configuration setup file...

WARNING: the generated configuration file
can be edited if necessary!
You can introduce any change to the configuration file
/Applications/physics/geant4_9.4.4/.config/bin/Darwin-g++/config.sh before the final installation. 
To do so, use a shell escape now (e.g. !vi /Applications/physics/geant4_9.4.4/.config/bin/Darwin-g++/config.sh).

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

Configurando

faq@Obatala.local/Applications/physics/geant4_9.4.4$ sudo ./Configure 
 
                --- Geant4 Toolkit Installation  ---
                  (setting environments for USER )
 
---------------------------------------------------
The Geant4 toolkit installation was found.
The files env.[c]sh will be copied to your current directory.
For setting Geant4 environments you should make:

source env.csh

or

. env.sh

It will also check G4WORKDIR setting and set it to
your HOME if needed.
You can use these files also for further modifications
(adding your own environments).
---------------------------------------------------
faq@Obatala.local/Applications/physics/geant4_9.4.4$ 

Configuren las variables de ambiente y correr un ejemplo.

export G4WORKDIR=$HOME
export DYLD_LIBRARY_PATH=/Applications/physics/clhep_2.1.0.1/CLHEP/lib
source /Applications/physics/geant4_9.4.4/env.sh

Esto nos permitirá trabajar en nuestro $HOME cualquier proyecto de geant4 (excepto los que no se configuraron a la hora de instalar). Hacer solo una vez source .bashrc. Las otras veces que se quiera usar geant4 no será necesario hacer lo mismo.

Ejemplo

Tomar la carpeta de ejemplos que viene con geant4

cd $G4WORKDIR
cp -r /Applications/physics/geant4_9.4.4/examples .
cd examples/novice/N02
make -j4

Estos nos generará un ejecutable en $G4WORKDIR/bin/Darwin-g++/ llamado exampleN02. Para correrlo hacer: ../../../bin/Darwin-g++/exampleN02 .
