Dear Khalid, dear David,
<div class=""><br class="">
</div>
<div class="">Thank you for your answers! I couldn’t find GATE in the Ubuntu Software Centre but that is likely a problem with the proxies of our institute which we weren’t really able to fix yet.</div>
<div class=""><br class="">
</div>
<div class="">Concerning the versions of GATE and Geant4, sorry for the confusion. Indeed, we tried first <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class="">GATE 9.1 together with Geant4 10.7.3</span> and then <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);" class="">GATE
 9.0 together with Geant4 10.6.3. We get the same error in both cases.</span></div>

 didn’t have to do this for a previous GATE 9.0 installation, also on an Ubuntu 20.04 machine. But this time, without specifying the C++ standard, we get another error trying to build GATE which refers to some root files actually</span><font color="#000000" class=""><span style="caret-color: rgb(0, 0, 0);" class="">…</span></font></div>

<div class="">Just an observation from the sidelines (these days I can spend much less time on GATE than I did in the past): the subject of your mail is about version 9.1, but in the build output messages I see source paths with version 9.0 in them. Can you
 clarify which version you are really trying to build? That can be important for whoever is going to try to reproduce this error.</div>
<div class=""><br class="">
</div>
<div class="">In principle the newest release is preferred. In case the above errors were really obtained with 9.0 source code, could you then try to upgrade to 9.1? Moreover, the next release is also just around the corner, this might also solve your problem
 (but maybe introduce a host of new ones :o) ). <br class="">

There was initially another problem that seemed to originate from root and Geant4 having been compiled with different C++ standards. We rebuilt Geant4 enforcing the C++ 17 standard and root is actually the downloaded binary which seems to work fine.<br class="">

Does anyone have an idea what the error during the GATE build could be and how to fix it?<br class="">
