Terminfo with Informix on Slackware

I'm trying to get terminfo to work with Informix SE 7.25.UC6 running on Slackware Linux 9.1. Slackware has terminfo installed in /usr/share/terminfo and I've set INFORMIXTERM=terminfo, but if I try to start dbaccess with TERM=wyse60 it says "The type of your terminal is unknown to the system". Slackware does include a termcap file with a wyse60 entry, so if I set TERMCAP=/etc/termcap-BSD (this is the termcap with the wyse60 entry) dbaccess works. Why doesn't terminfo work? I unset TERMCAP and still INFORMIXTERM=terminfo doesn't seem to work or at least it can't find the correct entry, but there is a wyse60 entry in terminfo.

I found this in the Informix release notes: UNIX systems that provide terminfo services but do not fully support the System V terminfo library will not recognize the INFORMIXTERM environment variable (which Appendix D describes). The terminfo library must include the following functions: setupterm() tigetstr() tigetflag() tigetnum() So maybe INFORMIXTERM doesn't work on Slackware since it's not System V, but rather BSD. I thought it was only BSD with regard to the init scripts, but maybe other stuff as well. I do have the above functions installed so it seems like it should work.

Slackware uses ncurses, which provides the given interface. The current version of ncurses is 5.5 (20051010) There's an faq at http://invisible-island.net/ncurses/ncurses.faq.html -- Thomas E.

I'm running ncurses version 5.3, will upgrading to 5.5 work with Informix?

There are two questions raised: a) does ncurses provide terminfo as indicated in the Informix release notes (I answered that one). b) does Informix actually use ncurses? (I don't know that one, don't have Informix available to inspect - if I had, it would be simple enough to do "ldd dbaccess" or whatever, to see if it's linked with ncurses, use strace to see what files it opens, etc). It's possible that Informix is using its own curses library. Coincidentally, I noticed last week (by downloading the source ;-) that Ingres does this - and only uses termcap underneath. If Informix isn't using ncurses' shared libraries, it's possible that it's using something like the AIX terminfo format, which isn't the same as ncurses (and Solaris, IRIX64). In that case, the application couldn't read the data in /usr/share/terminfo. -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
