My installation produces this error

There seems to be a error in the first line of this code from the .install file 32 bit linux. should it be '==' not '='?

if (( "$err_seen"=0 )); then
DO_FAIL
err_seen=1
err_count=$(( err_count+1 ))
fi

RM $TEMP \$this->_split2($m[0])& /dev/null

# Edit the $iraf and $imdir paths in mkiraf.*sh, *cl.*sh, and libc/iraf.h
# files.


Before this when I open iraf nothing is responsive. After I change that I get a failure on my installation.

What does my .cshrc need to look like? My current .cshrc is blank

My .cshrc~ looks like this

# Add iraf setup commands
if ( -e /home/dfelli/.iraf/setup.csh ) then
source /home/dfelli/.iraf/setup.csh
endif

This bug in the install script was discovered following the last release, a patched install script is available from

ftp://iraf.noao.edu/iraf/v216/support/install

At the point in the script where it is failing the script is attempting to edit the $iraf path into your startup files (e.g. .cshrc/.login if you use a C-shell, and .bashrc/.profile/.bash_profile/.bash_login if you use a Bash shell). If these files don't exist you would see a message but the installation should continue, could you post the error message you're seeing?

The .cshrc file isn't required to pre-exist, and likely won't if you use a Bash shell, but may be created anyway with the basic iraf setup you showed. You can do "echo $SHELL" at the unix prompt to see which shell you are using, likewise do an "echo $iraf" to see if/what the iraf directory is to verify that it is correct. Does the 'cl' command print any sort of error? What directory did you unpack iraf into?

That bad line of code is still in the install file is the top directory as of last week. I was using that file (/iraf/iraf/install) instead of the /iraf/iraf//unix/hlib/install.csh file because the install documentation said

%setenv iraf /path/iraf/
% cd $iraf/unix/hlib
% source irafuser.csh
% ./install -n

and './install -n' wasn't found and I didn't see the install.csh file.


furthermore on startup I think my problem was when I started iraf I was patient enough to wait literally 5 minutes for the program to load. not sure why it takes that long. My problem is solved unless you can comment on the long start-up time.

A long startup time is sometimes related to something happening in your .cshrc/.bashrc/.profile file, e.g. it's waiting for access to a file on an NFS partition, an rsh/ssh/wget or some other remote command is waiting for a network timeout, etc. You can start the CL by running the $iraf/bin.linux.vocl.e binary directly, e.g.

% setenv arch ".linux" # note the leading dot
% setenv IRAFARCH linux
% $iraf/bin.linux/vocl.e

If this starts immediately then try tracing the 'cl' command itself, i.e.

% sh -x $iraf/unix/hlib/cl.sh

to see where the wait is happening, if there is not output from the CL script right away then the problem is in your startup files somewhere.

Immediately this comes up with typing $iraf/bin.linux/vocal.e or cl

typing sh -x $iraf/unix/hlib/cl.sh prints out a lot of stuff quickly then it goes to

NOAO/IRAF PC-IRAF Revision 2.16.1 ... then a 5minute wait like above
-----------------------------------------------------------------

Then it's a networking timeout from the system version checker CHKUPDATE. Even if you're not on a network this should fail immediately but it appears to be trying to connect and then timing out either on your machine or the intervening gateway.

To disable this you can either comment out/delete the call to "chkupdate" in your login.cl file (and the system $iraf/unix/hlib/login.cl) or else once you are logged in set a negative interval parameter value, e.g.

cl\$this->_split2($m[0]) chkupdate.interval = -1

Note that if you don't have a login.cl in the current directory, you'll need to edit the global login file in $HOME/.iraf/login.cl
