iraf.net

I'm trying to install the new version 2.16.1 on an existing installation: linux, 64 bit, workstation.
I am using sudo. I put iraf-linux.tar.gz into /iraf/iraf. When I execute tar zxf iraf-linux.tar.gz,
I get:

tar: unix/f2c/libf77: Cannot open: File exists
tar: Error exit delayed from previous errors

This doesn't seem right. Any suggestions?

This could be either a permissions problem (i.e. the iraf$unix/f2c/libf77 file, and perhaps others, don't have write permission) or it may indicate a corrupted download file (e.g. a non-binary transfer, a hiccup downloading a browser link, etc). If you're updating an existing installation it is okay to simply delete the old system before untarring, otherwise check the permissions of the file in question. You can try untarring the file with

% tar tzvf /path/iraf-linux.tar.gz

to list its contents (which should also produce an error if it is corrupted).

I did look through the tar t and found that the libf77 should be a file, but in my installation it
is a directory with a lot of .c files.

So, I try putting a fresh installation into /iraf.new/iraf and executing the install script. Everything
seemed to work fine until it came time to execute 'cl'. It's having trouble finding a shared
library. The message that I get is:

/iraf.new/iraf/bin.linux64/vocl.e: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

Any ideas?
Thanks.

Sounds like you need to install the 'ncurses' lbraries on your system. On some RPM-based distributions this is the 'ncurses-libs' package, otherwise just install everything from the ncurses package in your control panel.

hi

I get the same problem, but I have the ncurses libraries on my system, I checked. Did you solve the problem?

The problem may be in the version of Linux you are using, e.g. the vocl.e binary requires libtinfo.so.5 but your systems comes with a different version of the shared library. You can check by doing:

% ldd /iraf/iraf/bin.linux64/vocl.e

(Adjust the iraf path and architecture as needed). If libtinfo.so.5 is listed as not found, check your /usr/lib or /lib64 directory for a "libtinfo.so.*" file to see what version you have. There's a good chance you can simply make a symlink called 'libtinfo.so.5' to that version, otherwise you'll need to find the rpm with the proper version.

If you're not sure what's going wrong, please post the 'ldd' output and your Linux version (and whether 32- or 64-bit).
