Hi Mark,
<div class=""><br class="">
</div>
<div class=""> The xMsg system now used by RootSpy requires C++14 and thus needs the gcc 5.3.0 compiler.</div>
<div class=""><br class="">
</div>
<div class=""> From what I recall, we needed to move to something other than 4.4.7 some time ago. Hovanes</div>
<div class="">did not want to change from the default system compiler at the time because he was worried</div>
<div class="">about stable controls systems being broken. We made the decision to split the environment so</div>
<div class="">that slow controls (GLUEX_TYPE=CONTROLS) computers would have a distinct environment</div>
<div class="">from the DAQ and monitoring nodes (GLUEX_TYPE=GENERAL). This split is made at gluon40.</div>
<div class="">The desktops (gluon01-gluon05) are considered slow controls machines.</div>
<div class=""><br class="">
</div>
<div class="">You can see where the GLUON_TYPE environment variable is set and how it is used in </div>
<div class="">/gluex/etc/hdonline.cshrc .</div>

Sascha S. asked for an offline build on /group/halld under GCC 5.3.0. Indeed if I log in as hdops on gluon100, GCC 5.3.0 is set up as the default, presumably using a module. I'm guessing that this has something to do with his request. If I log into the same
node as marki, this set up step is not done. And if I log into gluon03 as hdops, again, the set up is not done. Does anyone know why we need this version of GCC on gluons >= 100 under hdops?<br class="">
