Hello Carlo (and the list). Now it works (Athena/Artemis/Hephaestus). I didn't do an exhaustive investigation, I just checked that I could start the programs, get the X window (that I could never get before, with the error message) and read a project file. Thanks for the fix! Let me know if I can be of further help for your investigation of the problem. Regards denis Hi again Denis: On Mon, 24 Oct 2011, denis.testemale wrote:

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.

The problem is in the new build of pgplot5 with gfortran 4.6 and, possibly, the latest version of debhelper. In order to temporarily resolve this problem while I figure out how to fix it permanently, I have posted new pacakges for natty and oneiric on the debian-xray.iit.edu archive. Please let me know if it still won't work. Carlo -- Carlo U.
