Hi,
I've downloaded the iraf-macosx.tar.gz file. After gunzip and tar -xvf I tried the cl command and I get the following message:dyld: Symbol not found: ___stack_chk_guard
Referenced from: /iraf/iraf/bin.macosx/ecl.e
Expected in: /usr/lib/libSystem.B.dylibTrace/BPT trapThis is a Power PC G4 with the Mac OS X 10.4.11.
Any help would be greatly appreciated.
Regards.

Thanks Fitz,now cl runs properly.
However, I have now the following problem.
When I run gsextract (inside gemini, gmos packages) I get:GSEXTRACT -- Tue Oct 11 08:57:48 BRST 2011

I've checked the files and the files are there.
What have I missed?regards

The problem is the same in that the v2.15 binaries are not compatible with a 10.4 PPC system, I'd need to build a new set. However, the GEMINI package is still not able to use v2.15 so you'll need to install v2.14 anyway. See ftp://iraf.noao.edu/iraf/v214/PCIX/for the distribution files. Also, v2.14 external packages can be found in ftp://iraf.noao.edu/iraf/extern-v214Note this directory may not contain a full set of binaries for 'macosx'.

Fitz,
thanks again, I'll install IRAF v2.14.The Gemini version I have is 1.10 that was tested on IRAF v2.14, so I do not expect to have problems.Should I expect to have problems with other extern pacakges such as fitsutil, misc, nmisc (needed for gemini)?regards.

Hi again,
well, not so sure about what I've said.
After installing IRAF v2.14 I ran the routine gsextract (gemini, gmos). While the routine was processing the data cl died, and I did not receive any error message, just the prompt in my home directory.Any suggestions?cheers

It's hard to tell exactly what failed: Are you using the ECL binary from earlier in the thread or the one that comes with the v2.14 distribution? What was the task doing at the time it exited, i.e. do you know if it was a GEMINI task, a core IRAF task, or some other external package task?To track it down you could type "d_trace" before starting the task to trace the script execution an narrow things down. You might also try to attach a GDB debugger to the CL binary itself to trap an error in there. e.g. in another window % ps -efw | grep ecl.e # get the process id
% gdb /iraf/iraf/bin.macosx/ecl.e <process_id>
... type 'c' to continue execution, GDB should break at an error

Hi Fitz,
thanks for your answer.about your first question, I'm using ecl that comes with the v2.14 distribution.about the second question, I just do not know. gsextract works for some seconds and I have no idea what is the routine in use when cl dies.I've tried with d_trace and get what,
gsextract finished the process without errors!
In fact, I'm now watching the processed spectra!On the other hand, if I do not type d_trace before running the routine, cl dies.
I'd keep it that way, but it's somewhat boring and slow to see the infinite list of processes on the screen each time you run a task.regards
