Re: XEphem fails on MacOS 10.15.3 with Macports

 

Elwood,

thanks for trying to help. ?Yes, I am running xquartz; this all worked in the previous release. it broke with macOS Catalina 10.15.3

I am thinking to remove it all and rebuild from scratch, but I fear doing that so I hesitate.

I will no doubt kick myself when I get it running for having overlooked the obvious, but meanwhile (well, you get it).
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Thanks for the suggestion, Elwood. ?For me:

% echo $DISPLAY

/private/tmp/com.apple.launchd.nupkkTMJpP/org.macosforge.xquartz:0

%

% xephem

Building shell

Reading X resources

Checking args

Checking colormap

Re: XEphem fails on MacOS 10.15.3 with Macports

 

For what it's worth, for purposes here I don't think MacOS is much different than Linux, since it's BSD-based and there is a nice X11 distribution available to install seamlessly. ?Windows would be different, I think. When we eventually figure this out I don't think it will have turned out to be a big deal. ?Says Mr. Optimism...
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Have you checked your DISPLAY environment variable? On macOS the old favorite :0 does not work. At the moment mine is:

echo $DISPLAY
DISPLAY=/private/tmp/com.apple.launchd.Y3GlPNjYOH/org.macosforge.xquartz:0

This should be set automatically when you log in when xquartx is started by launchd but if not, try looking in /private/tmp for something similar then set it yourself, for example:

export DISPLAY=/private/tmp/com.apple.launchd.Y3GlPNjYOH/org.macosforge.xquartz:0
xephem

You are running xquartz right? Never use macports x11, that is way out of date, and trying to mix it with xquartz will lead to much grief. Uninstall if you have it then get , or try installing it again anyway in case it is messed up somehow.
Re: XEphem fails on MacOS 10.15.3 with Macports

 

xephem could stand to have a network of maintainers to help it over
these problems as libraries and operating systems change over time. I
remember in Linux it took some time and fiddling because it uses
xprint (I think it was) which has mostly passed out of common usage.
It would be a fairly thankless job I think, and I'm not much younger
than Elwood. I've never seen OS X, and i don't grok AppleSpeak.

Re: XEphem fails on MacOS 10.15.3 with Macports

 

MacPorts is MacOS release specific. In general with each release of MacOS, I¡¯ve had to update Xcode, and MacPorts. And as someone else pointed out, you want to make sure your XQuartz is up to date.

Sorry this didn¡¯t fix your problem.
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Not so obvious to me! ?But I did reinstall and got the same result.
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Just to eliminate the obvious, you did reinstall MacPorts, right?
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Thank you for the pointer. ?I've installed it and indeed it works well. ?Sometimes it's best not to try to solve a bunch of problems all at once!
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Don't know what's in Macports but the XEphem.app within my original disk1 ?is statically linked and still works fine on Catalina 10.15.3 with xquartz 2.7.11. One caveat is sometimes it helps to get xquartz running first by running something like xlogo before starting xephem.?
Re: XEphem fails on MacOS 10.15.3 with Macports

 

Unfortunately these tricks did not work for me. ?Thanks for the suggestions.
Re: XEphem fails on MacOS 10.15.3 with Macports

My best guess would be that the Catalina upgrade also upgraded some X11 libs (specifically libXt.6.dylib). I found the following post that while not related directly to XEphem, may provide a solution:

Alternatively, these two posts also deal with problems with the same library:

Hopefully that helps?

This does not appear to be a Macports problem strictly, as it compiles and installs properly.

Re: Script Error when starting XEphem on MacOS

 

I circumvented the issue going a different installation path. I compiled xephem from the sources and followed those installation instructions.
Re: Script Error when starting XEphem on MacOS

 

I doubt it since the path is only "/Applications/XEphem.app".
Re: Script Error when starting XEphem on MacOS

 

Could the "path to me" thing contain any special characters
that would trigger some kind of Unicode mess in the process ?

This normal starting script is suddenly causing the error.

Probably some new setting on my Mac (10.14.6) that I am not aware of that is creating the issue, but maybe someone here

Re: XEphem 3.7.7 live CD?

 

I don't use Windows, just little ARM machines like the Raspberry Pi.? Which runs XEphem fine, haven't tried it on a Zero.? It was written back in 386 and 486 days, I think there's some Fortran in there, pretty efficient.

Anyways, I just started a new project on my build service account, "astrotoolbox". Eventually the result will be a bootable hybrid iso image (can be written to a DVD or USB stick), unless it turns out bigger than 4.5GB in which case it'll be ony USB Stick, and on it you will find:

KDE Plasma 5 Desktop

GNOME Desktop

XFCE Desktop

XEphem 4.7.7

kstars

stellarium

cartes du ciel

and if I can pull it off the virtual moon atlas as well.

If there is demand there will also be VM images so you can run the whole thing in Hyper-V on your windows computer.
