When set to OFF, it means that the compilation uses the CLHEP that is included in the installation of GEANT4.</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1500964930070_12027"><span><br></span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1500964930070_12035"><span>Kind regards,</span></div><div dir="ltr" id="yui_3_16_0_ym19_1_1500964930070_12029"><span id="yui_3_16_0_ym19_1_1500964930070_12028">Konstantinos</span></div><div></div><div id="yui_3_16_0_ym19_1_1500964930070_12030"> </div><div class="signature" id="yui_3_16_0_ym19_1_1500964930070_12033"><div style="color:rgb(0, 0, 0);font-family:Arial;font-size:16px;font-style:normal;font-weight:normal;letter-spacing:normal;orphans:2;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;" id="yui_3_16_0_ym19_1_1500964930070_12032"><span style="font-style:italic;" id="yui_3_16_0_ym19_1_1500964930070_12031">-----------------------------------------------------</span></div><span style="color:rgb(0, 0, 0);font-family:Arial;font-size:16px;font-weight:normal;letter-spacing:normal;orphans:2;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;font-style:italic;"> Konstantinos Chatzipapas<br> Medical Physicist, </span><span style="color:rgb(0, 0, 0);font-family:Arial;font-size:16px;font-weight:normal;letter-spacing:normal;orphans:2;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;font-style:italic;">MSc<br></span><div style="color:rgb(0, 0, 0);font-family:Arial;font-size:16px;font-style:normal;font-weight:normal;letter-spacing:normal;orphans:2;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;"><div><span style="font-style:italic;"> <span style="font-weight:bold;">University of Patras</span></span></div><div><div><span style="font-style:italic;"><br></span></div><div><span style="font-style:italic;"><span class="Apple-tab-span" style="white-space:pre;"> </span> web page:<span class="Apple-converted-space"> </span><a rel="nofollow" target="_blank" href="http://www.physicsmag.com/">Physics Magazine</a></span></div></div></div></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> Στις 9:24 μ.μ.

ITK is now listed as <b>required </b>in the <i>Package Required </i>section </div><div style="font-size:12.8px;">(<a rel="nofollow" target="_blank" href="http://wiki.opengatecollaboration.org/index.php/Compilation_Instructions_V8.0">http://wiki.opengatecollabora tion.org/index.php/ Compilation_Instructions_V8.0</a>) . Is it <b>actually </b>required - <b>or </b>can I just keep the ITK compilation flag <b>off </b>when compiling GATE v8.0? I didn't have any compilation error when the flag was turned off so I wanted to double check that was okay.</div><div style="font-size:12.8px;"><br></div><div style="font-size:12.8px;">2. The <i>Geant4</i> section states that GEANT4_INSTALL_DATA and <b>GEANT4_USE_SYSTEM_CLHEP</b> are <b>mandatory</b>, which appears to contradict with the earlier statement from the <i>CLHEP</i> section "<span style="color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">Since the GATE V7.0 release, users can use the CLHEP embedded within each Geant4 distribution. This case, the CMAKE flag GEANT4_USE_SYSTEM_CLHEP, which is OFF by default, must stay OFF.</span><span style="color:rgb(37,37,37);font-family:sans-serif;font-size:14px;">" Can I keep GEANT4_USE_SYSTEM_CLHEP <b>off</b>? Again there were no compilation error so I would like to make sure I installed GATE correctly.</span></div><div style="font-size:12.8px;"><span style="color:rgb(37,37,37);font-family:sans-serif;font-size:14px;"><br></span></div><div style="font-size:12.8px;"><font color="#252525" face="sans-serif"><span style="font-size:14px;">Many thanks,</span></font></div><div style="font-size:12.8px;"><font color="#252525" face="sans-serif"><span style="font-size:14px;"><br></span></font></div><div style="font-size:12.8px;"><font color="#252525" face="sans-serif"><span style="font-size:14px;">Ed</span></font></div></div></div>_______________________________________________<br>Gate-users mailing list<br><a ymailto="mailto:Gate-users@lists.opengatecollaboration.org" href="mailto:Gate-users@lists.opengatecollaboration.org">Gate-users@lists.opengatecollaboration.org</a><br><a href="http://lists.opengatecollaboration.org/mailman/listinfo/gate-users" target="_blank">http://lists.opengatecollaboration.org/mailman/listinfo/gate-users</a><br><br></div> </div> </div> </div></div></body></html>
