Are you talking about a Snap installer package?

Dear members of the XEphem community,
I am using XEphem for basic practical courses on celestial dynamics in a Bachelor for would-be primary school teachers. Unfortunately, most students experienced the same problem during the classes: selecting a date by clicking the month or year in the main window / Calendar panel caused XEphem to crash (needing to kill and restart it). Contrarily, no problem was reported to me when they typed the date in the main window / Time panel. Clicking the day of the month or forward/backward buttons in the main window / Calendar works fine.
All PCs run standard Ubuntu 20.04 on a stand-alone install (no VM or so).
Thank you in advance for any advice!
Yours,
Maxime

Thanks - it's pretty clear. I'll try. But it's looking like the end-of-the-line for XEphem.

I tried that and the make went further until it hit:

I think the problem is that motif is completely deprecated.

I have since found KStars. It's almost as good as xephem. It has bugs

here and there that cause it to crash but I it gives a similar interface

that xephem does.

Hello,

I have successfully installed XEphem on Ubuntu 18.04 using the libxp

package from Sergio Oller:

sudo add-apt-repository ppa:zeehio/libxp

sudo apt update

sudo apt-get install -y libxp-dev

Though I have not tried it, it seems that Sergio has updated it to 20.04.

Yours,

Maxime

Too much is deprecated which keeps breaking stuff. It's an advantage

of  Linux From Scratch maybe.  Or one of the BSDs.  Xmu is part of

Motif, you need the dev stuff with libraries and include files.  And

it may not find everything even though you have it because the places

things are kept change  Locate is about the 4th thing I usually

I tried two routes, neither worked:
#1 Install using the linux_install.sh file, then run the installed
version
Result: xephem: error while loading shared libraries: libXP.so.6: cannot
open shared object file: No such file or directory
Analysis: After much searching and library install attempts, this file
seems long deprecated and not available for ubuntu 20.04

#2 compile from scratch using make MOTIF=../../libXm/linux86 (with the
MOTFI and MOTIFL variables suitably modified in the makefile)
Result: crash because aavso.c can't find X11/extensions/Print.h The
directory exists but Print.h does not because it is part of Xprint which
has been deprecated since 2008 according to wikipedia.

Has anyone been able to make xephem work on ubuntu 20.04? If so how?

Yep. Have compiled and installed it on an Ubuntu 20.04 box. Cannot remember
any problems, but needed to install some libs, probably the ones for Motif.

I will try again tomorrow and see, whether I can reproduce the issue you
have and how to fix it...

I vaguely remember having to build xprint from source, this was on a
Raspberry Pi back a couple Raspbian versions. You could try searching
the archives of this list for xprint, but I think I mentioned it on
the raspberrrypi.org forum.
See about the middle of the first page at

which was my post. xprintf vanished between Jessie and Stretch but it
tells on that page how I got it installed.
