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

I generally write notes for me..... so, apologies in advance. ?I don't always do the best job.

Is this still a live issue?

I am running XEphem without error on 20.04.?

These are my notes. ?They may be cryptic. ?If you need clarification, let me know. ?I'll clean them up.

Hope you achieve success.

Thanks.

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

/usr/bin/ld: cannot find -lXmu

collect2: error: ld returned 1 exit status

make: *** [Makefile:196: xephem] Error 1

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
