iraf.net

We upgraded our Linux systems to SUSE Linux Enterprise Server 12 (SLES 12 SP1) and I'm having a little trouble. Our system guys have said that if we have our own code, we should recompile it. My iraf is a personal copy. I'm using 64-bit iraf. When I try to execute cl, I get:

/home/duvall/iraf/bin.linux64/vocl.e: symbol lookup error: /lib64/libncurses.so.5: undefined symbol: _nc_outch_sp

And when I try to execute xgterm:

/home/duvall/bin/cl_w: line 1: /home/duvall/.iraf/bin/xgterm: No such file or directory

(but it is there)

Do I need to download a new version or recompile?
Thanks.

This error is just starting to appear in Google and looks to be an issue in the ncurses library itself, that symbol isn't explicitly referenced in IRAF from what I can tell. It's possible this could be resolved using /lib64/libncurses.so.6 but you may need to have that installed first. If you do have a /lib64/libncurses.so.6 on your machine you can test whether it fixes the problem by doing something like:



and then start the CL. Unfortunately it is no longer possible to build the CL as a completely static binary on most systems. If you want to try relinking the binary on your system to resolve the problem, then try:



Then try executing the 'vocl.e' binary created. If that works do a "mkpkg update" to install the binary, it should be necessary to relink the rest of the system but I can tell you how to do that as well.



The X11IRAF tools are still 32-bit binaries so it is likely that the binary won't run because you need to install the 32-bit compatibility libraries and ELF binary support. We don't use SuSE so I can't say specifically which files you'll need to install. the sysadmins should be able to help and keep in mind you'll need 32-bit X11 libraries as well.
