Thank you very much! With your help I could install IRAF and every thing else in my mac. The button worked very well. Do you plan to make a source with the new version of the IRAF 2.14.1 and X11IRAF 2.0?

I plan to release the source and fix the download link ASAP.

Hmm, the button does not work with a scisoft install of iraf, which is rather common these days, I presume. The inability to start ecl is also a disadvantage. Don’t you want to make the source code available, so that we can make it work in 2010? Thanks!

I am not sure if I am stupid or what … but where in Earth can I download the IRAF Button on this web site?? I can’t find it. Thanks!

If you have the Darwin version of ds9, then just cd to your desktop, make a /usr/local/bin/ directory, (with sudo) and then move ds9 into /usr/local/bin. I think it might look for ds9 in /usr/bin too, but I'm not sure.

You can always use "show package contents" on the IRAF button and then find the appropritae .csh file to edit it and change the path.

The "MacOS X" version of ds9 is some .app wrapper for the darwin version and will just run when you double-click it.

Marcos,

I'm still having a small problem with the IRAF button, it does not launch ds9.

I get an error message;

csh:PATH=/usr/local/bin/ds9: Command not found

The thing is ds9 is currently on my desktop, and I can not find the directory that the IRAF button is looking in.

How do I change the path as that would seem to be easier?

Please let me know

(Running IRAF2.13 Beta2 on a G4)

Thanks

Nick

Ah, so you’re using fast user switching but not logging out the previous user. (In this sense, really only user is doing anything at any one time, but they’re both logged in.) I suppose you choose to not log out user 1 so that they can keep all their windows and such open.

Well, I can look into changing the IRAF button but … it clearly wasn’t designed with this sort of simultaneous use of X11 in mind. Other apps also don’t work with fast user switching ,like I believe iTunes. For now, until I can try to deal with DISPLAY and such you’ll have to quit X11 before the second user logs in … or just get by launching IRAF and ds9 the old fashioned way.

Click on the light switch, then Accounts at the beginning of the last row. Click on the lock and enter your password. Click on "Login Options" at the bottom of the list of user names. Click "enable fast user switching".

From now on, you will see your name at the upper right of the screen. Click on your name to switch to another user. You'll have to enter the other user's password, then you get a goofy animated display, followed by a desktop for that user. You can change back and forth among users arbitrarily.

Yeah, the IRAF button was never intended or tested for multi user machines. It definitely does not make "proper use" of the DISPLAY variable, I'll tell you that right now.

So, how exactly are two people logging into the Mac environment of the same machine at the same time? I didn't think that was possible... or someone ssh'ing in or something similar?

I am having two problems with the iraf button on a multi-use machine.

First if one user is running the iraf button and leaves their desktop running but another user logs in to a second desktop to run iraf then I get an error message that reflects that display :0.0 is not reachable (the second user of course would be :1.0) so it doesnt look like the iraf button is properly making use of the DISPLAY environment variable.

Second if one user has run the iraf button and has closed up their iraf session, shutdown X11 and then logged out. A new user who logs in and runs the iraf button will get X11 to startup, iraf to startup however ds9 never displays and no errors are displayed. It takes a reboot of the machine for the iraf button to launch ds9 properly. Launching ds9 manually (from the applications menu or from an xterm) does work however. It appears a mystery process is blocking the display of ds9 at launch.

We are running MacOSX version 10.4.10 on a 2 x 2.66 Dual Core Intel Duo Xenon machine. Iraf was installed the old fashion way (not with your tools) and we are running the latest.

Any help would be appreciated.
