I'm having problems with the ECL install. I I downloaded the ecl_install_linux.csh script and ran it as root. l get the following messages and no ecl.

ECL V0.9 Installation
=====================

Build Date: Tue July 3 15:43:33 JST 2007

For each prompt: hit <CR> to accept the default value, 'q' to quit,
or 'help' or '?' to print an explanation of the prompt.

tail: cannot open `+454' for reading: No such file or directory
uudecode: _ecl: No `begin' line
cat: ecl_tar.gz: No such file or directory

gunzip: stdin: unexpected end of file
Updating cl.csh script in hlib directory ....
mv: cannot stat `cl.csh.PCIX': No such file or directory

chmod: cannot access `ecl.e': No such file or directory

I saw http://iraf.net/phpBB2/viewtopic.php?t=86117&highlight=ecl+tail , but l couldn't understand what to do.
I hope someone can help me.

The 'tail' command has changed in recent linux systems. The post you reference means that you need to edit the ecl_install_linux.csh script to add a '-n' flag to the 'tail' command on line 401 of that file, i.e. it should read:

tail -n +$SKIP $0 > /tmp/_ecl.$$/_ecl      # unpack the files

If you then encounter a problem about an unresolved termcap library you should download the binary at http://iraf.net/ftp/pub/fitz/ecl.e and manually install it in the $iraf/bin.linux directory. Note that if you're using the v2.13 release from this site the ECL is already included in the distribution as the default.
