XEphem fails on MacOS 10.15.3 with Macports

SpikeLightfoot All Messages By This Member #3709 After upgrading to Catalina, XEphem (installed via Macports) fails at runtime: % xephem Building shell Reading X resources Checking args Checking colormap Building icon Building main window system Connecting actions Building main menu bar Warning: Fatal Error: _XmGetDefaultDisplay cannot be used prior to VendorS.Initialize, returns NULL Segmentation fault % This does not appear to be a Macports problem strictly, as it compiles and installs properly. ?
Rick Towns All Messages By This Member #3710 开云体育 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? ?

SpikeLightfoot All Messages By This Member #3711 Unfortunately these tricks did not work for me. ?Thanks for the suggestions.
Elwood Downey All Messages By This Member #3712 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.?
SpikeLightfoot All Messages By This Member #3713 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!
Bruce Skelly All Messages By This Member #3714 Just to eliminate the obvious, you did reinstall MacPorts, right?
SpikeLightfoot All Messages By This Member #3715 Not so obvious to me! ?But I did reinstall and got the same result.
Bruce Skelly All Messages By This Member #3716 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.
David Reed All Messages By This Member #3717 I am seeing failure as well; I get the error message: "can't open display" twice; then it quits... I tried rebuilding it which seemed successful, but same error. I tried previous suggestions to no avail; I am no OS X guru, so detailed suggestions would be welcome. Thanks in advance.
ab1jx All Messages By This Member #3718 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. toggle quoted message Show quoted text On 2/21/20, David Reed <w5sv.dave@...> wrote: I am seeing failure as well; I get the error message: "can't open display" twice; then it quits...

Elwood Downey All Messages By This Member #3719 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.
SpikeLightfoot All Messages By This Member #3720 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...
SpikeLightfoot All Messages By This Member #3721 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 Building icon Building main window system Connecting actions Building main menu bar Warning: Fatal Error:? _XmGetDefaultDisplay cannot be used prior to VendorS.Initialize, returns NULL Segmentation fault %?
David Reed All Messages By This Member #3722 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).
David Reed All Messages By This Member #3723 Further investigations revealed that it was quartz that was "broken"; reinstalled it and did a fresh installation of the execrable of XEphem, and all is well. Thanks to all for your help & support.
David Reed All Messages By This Member #3724 Too many typos; sorry for all that; quartz was failing..reinstalling that and the executable of XEphem fixed it all up.
SpikeLightfoot All Messages By This Member #3725 Uninstalling XEphem from Macports, reinstalling XQuartz, and rebuilding XEphem in Macports still failed. ?I downloaded the 3.7.7 source code, installed OpenSSL via MacPorts, applied the two patches in the User Contrib directory, and XEphem built successfully. I'm thinking something is broken with Macports after all.
SpikeLightfoot All Messages By This Member #3726 Other Macports users report the same bug:? Until the port is fixed XEphem is DOA via Macports, it seems.
