Greetings.

I am trying to install IRAF on Linux Mint 17.3. I used the directions on the following webpage as a guide:

http://www.iac.es/sieinvens/siepedia/pmwiki.php?n=HOWTOs.IrafMacOSX

The tar file that I used is:

ftp://iraf.noao.edu/iraf/v216/PCIX/iraf.lnux.x86_64.tar.gz

So, I unpacked that, and ran the following commands without error:

export iraf="/iraf/iraf/"
sudo /iraf/iraf/install --system
cd /iraf/iraf/extern/
sudo ./configure
sudo make check
sudo make fitsutil mscred mscdb stecf tables stsdas ...
cd ~/
mkdir iraf ; cd iraf
mkiraf


But then when I type cl, I receive the following error message:

/usr/local/bin/cl: /iraf/iraf//unix/hlib/irafarch.csh: /bin/csh: bad interpreter: No such file or directory
ERROR: No /iraf/iraf//bin./vocl.e binary found.


What's going on?

Looks like you need to install 'tcsh' to have a valid C-shell.

How do I do that?

Try:

% sudo apt-get install csh tcsh

I received the following error message:

E: Invalid operation csh

Then try just "sudo apt-get install tcsh" instead. I don't run Mint so I don't know specifically what the package name is. The point, however, is that you need to install a C-shell in the OS.

Something happened... I thought that I included the word "install" because I tried it like 5 times and I kept getting that E: error message.

Well I just tried it again and it did something different.

When I enter

sudo apt-get install csh tcsh

it doesn't do anything, it just enters it, and a new % line appears.

When I enter

sudo apt-get install tcsh

the same thing happens. It doesn't appear that any processes take place.

If there is a /bin/csh command on your machine it just means the install worked and subsequent commands didn't need to do anything. Does the 'cl' command now work?

No. When I type cl, I receive the following error message:

/usr/local/bin/cl: /iraf/iraf//unix/hlib/irafarch.csh: /bin/csh: bad interpreter: No such file or directory
ERROR: No /iraf/iraf//bin./vocl.e binary found.

Is there a /usr/bin/csh instead? If so, you can make a /bin/csh link with

% sudo ln -s /usr/bin/csh /bin/csh

and the paths should resolve.

IRAF v2.16 should work with just a Bourne shell but the C-shell files are still available. Use "echo $SHELL" to see what shell your user account is currently using.

The folder

/usr/bin/csh

does not exist.

I tried entering

sudo ln -s /usr/bin/csh /bin/csh

and then typing

cl

I still get the same error message.

When I enter

echo $SHELL

it returns

/bin/bash

I will be out of the office where the machine is stationed, for a few days, so let's pick up with this again on Monday.

Greetings again. I will be in today but then out of the office (and away from this computer) until mid-January.

So, what's the following step to get this to work?

Fundamentally, the problem is that you need to install a C-shell in the OS and for some reason the 'apt-get' command isn't working. That's an issue for another forum or some Googling on your part.

IRAF-wise, the 'cl' command is being installed as a Bash script, but it appears that within that script lines 95-98 read:



So instead of sourcing the Bash version of the 'irafarch' command it looks for the C-shell version. Simply editing this script to change the 'csh' to a 'sh' should fix the problem. There are similar crossovers between shells where the Bash version calls C-shell in

ecl.sh
vocl.sh
irafuser.sh
fc.sh

These should also be edited to change the 'csh' extension to 'sh'. All of these files live in the $iraf/unix/hlib directory.

So I got apt-get to work, I think that it was a shaky wireless connection that seemed to cause the issue.

I was able to install tcsh and csh.

So, when I go to type

cl

to launch IRAF, I receive a different error message:

bad type spec `s' in `/222&'
bad type spec `i' in `C'
must specify at least name,type,mode for `pic:StandardsBiryukov+:1998)'
bad spec type `j' in `C'
ERROR: cannot read parameter file `vo$vo.par'
called as: `cl ()'
Error while reading login.cl file - may need to rebuild with mkiraf
Fatal startup error. CL dies.


The only issue that I saw in the prompt window while installing csh was with scrollkeeper, but I'm not sure what that has to do with this.

Looks like a parameter file or uparm directory was corrupted somehow. Try doing a new MKIRAF and reinitialize your uparm directory, if you see the same errors then try reinstalling from the tarball, that text is not part of the normal iraf distribution.

So here is an update. I deleted the old and new login.cl files, restarted the Terminal, re-did

mkiraf

then entered cl again, and this time I got a different error message:


ERROR: cannot open `uparm$22826' for writing
called as: `cl ()'
Error while reading login.cl file - may need to rebuild with mkiraf
Fatal startup error. CL dies.


I will attempt to do a fresh install from the tarball and see what happens.

Hey it works finally.

So I'm guessing that before I install IRAF, tcsh and csh need to be installed first, or else I would end up going through this whole ordeal again, correct?

During the install, under Editing Paths, the following double error message appeared:

/iraf/iraf/install: line 1006: ((: 0=0 : attempted assignment to non-variable (error token is "=0 ")
*** Cannot
/iraf/iraf/install: line 1006: ((: 0=0 : attempted assignment to non-variable (error token is "=0 ")
*** Cannot

I'm not sure if that matters.
