[Ifeffit] Athena crashing with "Larch_Server not found"

Hello,


Thanks for the answers, Bruce and Matt.

I did some more desperat tries installing packages on my ubuntu - ending up with it crashing, no graphic interface, and forcing me to reinstall it - which show you my mastering of computers in general!


Now, followed again the instructions and ran into new problems. Can't get over the "./Build test" (terminal output: screen_message_Frederik_test.txt) and "./Build install" gives error (terminal output: screen_message_Frederik_install.txt).


What is the problem now? Im very sorry for not being able to solve it myself!


Thanks for all attention in first place.


Frederik

Hi Frederik,

Also sorry for the slow response.  I was away from the lab all of last week.

As Matt said, he and I are working on transitioning Demeter from using
Ifeffit by default to using Larch by default.  If you were inclined to
help us out by installing Larch and testing Demeter with Larch, we would
be grateful.

I'll say that the benefits will pay off in the long run.  Having Larch
behind Demeter will enable a lot of new features in Athena and Artemis.
For example, I have some ideas for improving Athena's linear combination
fitting in ways that cannot be done (or at least not easily) with
Ifeffit.  It'll be cool.

That said, it is quite possible that the HEAD of the git repository
could have problems.  I haven't properly documented this yet, but it is
possible to force Demeter to skip the check for a Larch server and fall
back to using Ifeffit (which will continue to be available even after we
complete the switch to larch).

The easiest way to do so is to set a special environment variable.  Try
starting Athena with this command:

    DEMETER_FORCE_IFEFFIT=1 && dathena

or, more permanently within a bash session

    export DEMETER_FORCE_IFEFFIT=1

then a normal "dathena" command will fall back on using Ifeffit.

This behavior may change with notice, but I will try to keep the
documentation at the website up-to-date.
