[Ifeffit] Report problem in Demeter install

[Bruce Ravel]

Charles,

It is a bad use of my time to answer questions about the software
other than on the mailing list

   http://cars9.uchicago.edu/mailman/listinfo/ifeffit/

You'll notice this email is CCed to the mailing list.  Any further
conversation on this topic must use the mailing list.

Am I to assume that you are trying to build from source?  The link is
to the part of that page that discusses NOT building from source....

All the standard questions apply.  You really have to give me
something to work with....

   * Is this linux?

   * What version of linux?  Or whatever operating system you are
     using.

   * What version of perl?  (perl -v)

   * What version of gcc?   (gcc -v)

   * Did you successfully install Ifeffit and Pgplot?  (Step 1)

   * What happened when you did "perl Build.PL"?

   * Is cpan configured reasonably?  (Step 3a)

   * Did you read this: https://gist.github.com/waveform80/3959252 ?
     It's really helpful -- Dave Hughes did a bang-up job.

I've answered this question over a billion times times on the mailing
list.  Ifeffit, the backend Athena uses for its XAS functionality, is
written in Fortran.  Fortran has static memory allocation.  As
normally delivered Ifeffit can handle about 60 groups, given the way
Athena uses memory.

You have two options.  (1) Compile Ifeffit to use more memory.
Instructions can be found by searching the mailing list.  (2)
Live with the fact that you cannot do 200 spectra at a time.

As Matt has pointed out many times, Larch will fix this problem.  The
day when Athena can use Larch is fast approaching.  I'm getting there,
but I have a lot of things to do each day.  So it takes time.
