Mac Pro Problem

Karen Kwitter wrote on Aug 29, 2006

Has anyone else tried to install macintel IRAF on a Mac Pro (the new tower)? On mine, all is well EXCEPT xgterm, which segmentation faults every time. This is on a fresh install of everything, OS on up. I do not have this problem on a MacBook Pro with the same version of IRAF and the OS, so it is not simply an Intel issue (although I do note that xgterm is the only component that is still PPC native and runs under Rosetta). It just works on the Intel laptop but doesn't on the tower, with the S/W as identical as I can make it. Any ideas?

Hi Karen,

I put a working binary from my MBP at http://iraf.net/ftp/pub/fitz/xgterm.ppc, please let me know if that still fails.

XGterm still needs updating for both macintel as well as cygwin (and some linux issues). Being based on the original Xterm code though, it's a painful task I've managed to put off so far.

Cheers,

It still fails with a segmentation fault. The file you just directed me to is identical to the one in the distribution, anyway. I'm afraid it's something peculiar to the
Mac Pro (firmware, Rosetta version, 64-bit???), because it works fine on the MacBook Pro (S/W load as identical as possible). I'd be interested to know if anyone has gotten xgterm to run on a Mac Pro.

Thanks very much!

Hi Karen,

I got access to a machine and found there was no easy fix other than to go ahead and finish the xgterm port to the latest OSX (the problem affected PPC as well). There is now a working, native i386, xgterm binary in

http://iraf.net/ftp/iraf/x11iraf/x11iraf-v1.5DEV-bin.macintel.tar.gz

The macosx binaries were updated as well, I'll update other platform binaries as time permits.

Cheers,
-Mike

Thanks, Mike! It worked, as you said it would. Good news for all those Mac Pro/Tiger users out there. Now the coffee out of my iraf.net mug will taste even better!

Mike,

Thanks very much for posting a new xgterm binary for 10.4.8 macintels. This got xgterm working for me again after the 10.4.8 update.

Unfortunately now I can't seem to successfully ssh using xgterm.

I'm using

ssh -XY servername

but regular ssh, ssh -x, etc are not working either.

What happens is, I'll see the password prompt, I'll type the correct password and then nothing happens. I don't get a command prompt or a welcome message.

Doing ssh the same way in xterm works fine, so that's why I have a feeling that it is an xgterm issue.

Can you give me any advice?

Thanks!
Sarah

I doubt it's strictly an xgterm thing, ssh is just another application like 'ls' or 'cat' as far as xgterm is concerned. One difference may be something like in an Xterm you source your .login file but not with XGterm (i.e. the '-ls' flag to xterm or the 'loginShell' resource being set, perhaps in the system default). Does starting XGterm with "xgterm -ls" make a difference?

Note you can add a '-v' flag to ssh to print some debug information, if you're getting the password prompt it will tell you whether/what's happening afterwards.

Mike,

Here's what I get from -v after the password prompt and entering my password:

debug1: Authentication succeeded (password).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Requesting X11 forwarding with authentication spoofing.

I'll explore the other options you mentioned in the mean time.

I ran into the XGterm problem right after upgrading to 10.4.8. I recompiled from source (before I checked in the forums here) and it works fine again. The x forwarding from my linux box works as well (ssh -XY), albeit with a message saying "No xauth data...".
