Hi Denis: This is strange. I typically do not run Ubuntu but I do run Debian unstable and I have had no such problems. It looks like ifeffit, libifeffit-perl and pgplot5 have been rebuilt by Ubuntu (the version number is the key). I suspect that the build has been done improperly and that is the cause of the problem. You should at least submit a bug to Ubuntu so that they can fix the builds. I will look into what might be the problem. I might just put the packages in question im my archive. I may ask you to try later today. Carlo On Mon, 24 Oct 2011, denis.testemale wrote:

Dear members of the list,

I thought I would send this message to Carlo Segre (who packages Ubuntu versions of Horae), but this message might be of interest to other persons on the list, and someone else may even have a solution for me.

Problem: after upgrading to Ubuntu Oneiric 11.10, I now cannot start Athena/Artemis, with the following error: /usr/bin/perl: symbol lookup error: /usr/lib/libpgplot.so.5: undefined symbol: XOpenDisplay Hephaestus runs, but I tried to plot something from it (i.e. f' and f'' plots) and it crashes (with the same error).

I uninstalled and reinstalled Horae with the sources list up to date (deb http://debian-xray.iit.edu sid main contrib non-free deb http://debian-xray.iit.edu oneiric main contrib non-free) but without success.

I googled a bit about the problem, but didn't find anything convincing (the only answer that is promising is unreachable).

Among the information you might need:

##lsb_release -a: Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric

##dpkg -l | grep ifeffit ii ifeffit 2:1.2.11d-7build1 Interactive XAFS analysis program ii libifeffit-perl 2:1.2.11d-7build1 Perl extensions for IFEFFIT

##dpkg -l | grep horae ii horae 071~svn536-1 interactive graphical processing and analysis of EXAFS data ii horae-doc 072-1 help file documentation for athena and hephaestus

##dpkg -l | grep pgplot5 ii pgplot5 5.2.2-17build1 large subroutine library for plotting scientific data

##dpkg -l | grep perl-tk ii perl-tk 1:804.029-1.1 Perl module providing the Tk graphics library

##perl -e 'use Config::IniFiles; print $Config::IniFiles::VERSION, $/' 2.68

Thanks for your help on this one.
