Elwood, I did as you suggested and still no juice; I suspect I am loading thing in the wrong places or some such; as a clue, I provide the following show of a terminal window contents:

drwxr--r--?? 7 davereed? staff?????? 224 Mar? 5 15:15 .
drwx------@ 75 davereed? staff????? 2400 Mar? 5 06:01 ..
-rw-r-xr-x@? 1 davereed? staff?????? 828 Mar? 5 15:10 XEphem.app
-rw-r--r--@? 1 davereed? staff????? 2070 Nov 16? 2003 XEphem.png
-rwxr--r--@? 1 davereed? staff????? 2378 Jan 20? 2013 linux_install.sh
drwxr-xr-x? 14 davereed? staff?????? 448 Mar? 5 15:15 xephem-3.7.7
-rw-r--r--?? 1 davereed? staff? 38010880 Aug 12? 2015 xephem-3.7.7.tar

Davids-MacBook-Pro-15:XEphem davereed$ pwd
/Users/davereed/Library/XEphem
Davids-MacBook-Pro-15:XEphem davereed$?

I am not very computer literate and the directions on installing and README seem a bit sparse for an ignorant cuss like me.

It acts the same whether I try to run the app from the Download folder, or the path listed above...

Would there be any instructions that are very explicit and step by step for folks like me?

Thanks!

?Elwood Downey 9:22am???#3657?? Hi David, I suspect it is an xquartz problem, not xephem. I'm having no problem using the standard xephem??and xquartz??on?macOS 10.14.3. I suggest you remove all vestiges of both and install fresh.

Agree with Tristan, you can use the X11 forwarding!, and on Windows you can use putty.exe (with the X11 Forwarding enable) and then use the Xming to see you Xephem interfase.

Hi Jeff,
Another setup you can try is on Windows 10, you can install the Microsoft Subsystem for Linux and XMing.
In stall XEphem in an Ubuntu instance in Windows 10.
export DISPLAY=:0.0 with XMing running and you will have XEphem running on Windows.
You can write a script and assign it an icon and run it from the Windows 10 Desktop.

The question will be if XEphem will be able to address the drivers through the setup?

Hi, Jeff.

If you enable remote access on the Windows system, you should be able to use Microsoft Remote Desktop on both your Mac and mobile devices to logon to the Windows desktop and control things.

Hi all,

Brand new to both xephem and to the group.

I am particularly interested in xephem because xmtel works with xephem
and xmtel has telescope drivers for Sidereal Technology. I recently
converted my JMI NGT-18 to the sitech controller and servo motors but
sitech's software to date is windows only.

I have an Odroid XU4 running Ubuntu 18.04 that I want to use for xephem
/ xmtel and to drive the sitech controller. I want it to run headless
so I'd been planning on a VNC setup using x11vnc and connecting to the
XU4 either from my Mac or from an old 1st generation iPad.

I use x11vnc on the XU4 now and connection to it with tigervnc from the
Mac it is rock solid for every application except xephem. Connecting to
xephem causes the tigervnc client on the Mac to crash within a couple of
minutes of use. Every time. x11vnc on the XU4 remains running and I
can make a new connection almost immediately that will last another
couple of minutes. I've also tried the RealVNC client for the Mac and
hauled out a windows computer to test but unfortunately got the same crash.

Is this a known problem and if so is there a solution?

Alternatively I can do X forwarding from the XU4 but that limits me to
the Mac and Quartz.

Thanks!
