Then, from your home folder on the command line, you can type the following to make sure that the file exists:</div> <div><br> </div> <div>ls -a</div> <div><br> </div> <div>It should show all the files in this folder, including .bashrc (or .cschrc). If it does not exist, you can create it in your favourite text editor. Make sure to save it as .bashrc (or .cshrc) with no additional extension.</div> <div><br> </div> <div>Open .bashrc (or .cshrc) with your favourite text editor. Make any appropriate changes. For example, you could add the following line if it is not already there:</div> <div><br> </div> <div> <div>source /path/to/geant4/bin/geant4.sh</div> </div> <div><br> </div> <div>Save and close the file. From the command line, make sure to re-source the .bashrc (or .cshrc) file to take the changes into account:</div> <div><br> </div> <div>source ~/.bashrc</div> <div><br> </div> <div><br> </div> <div>Hope this helps.</div> <div><br> </div> <div> <div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; "> <div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "> <div>Marc</div> <div><br> </div> <div><br> </div> <div><br> </div> <div>__________________________</div> <div><br> </div> <div>Marc Chamberland, MSc</div> PhD candidate<br> Department of Physics<br> Carleton University<br> Ottawa (ON)</div> </span></div> <br> <div> <div>On 2013-06-28, at 1:36 PM, Felix Rangel <<a href="mailto:felix.j.rangel@gmail.com">felix.j.rangel@gmail.com</a>></div> <div> wrote:</div> <br class="Apple-interchange-newline"> <blockquote type="cite"> <p>I didn't do the g4 data on option when I installed geant4, so I have to manually add paths to the data libraries.
