[Halld-online] GCC 5.3 on the gluons

[David Lawrence]

Hi Mark,

  The xMsg system now used by RootSpy requires C++14 and thus needs the gcc 5.3.0 compiler.

  From what I recall, we needed to move to something other than 4.4.7 some time ago. Hovanes
did not want to change from the default system compiler at the time because he was worried
about stable controls systems being broken. We made the decision to split the environment so
that slow controls (GLUEX_TYPE=CONTROLS) computers would have a distinct environment
from the DAQ and monitoring nodes (GLUEX_TYPE=GENERAL). This split is made at gluon40.
The desktops (gluon01-gluon05) are considered slow controls machines.

You can see where the GLUON_TYPE environment variable is set and how it is used in
/gluex/etc/hdonline.cshrc .


Regards,
-David

People,

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?
