so this may be a dumb question, but i haven't been able to find any
documentation that addresses this. 

i installed my own terminfo directory in $HOME/share/terminfo
in bash, i can do:

[sepia]$ echo $TERMINFO
/home/will/share/terminfo
[sepia]$ export TERM=xterm-xfree86
[sepia]$ echo $TERM
xterm-xfree86

but in zsh:
sepia% echo $TERMINFO
/home/will/share/terminfo
sepia% export TERM=xterm-xfree86
zsh: can't find termcap info for xterm-xfree86
ˆ‰%

this machine doesn't have zsh so i'm running zsh from $HOME/bin/
did i need to tell zsh the location of terminfo when i compiled it? do i
just need to set different environment variables?

if termcap is needed, i have a current copy of that in $HOME/etc/termcap

i'm having the same problem with tcsh, so i'm assuming there's just some
variable i need to set.

bash treats the TERMINFO parameter as special, and resets the terminal every
time it changes.  zsh (and tcsh, I assume) don't currently know about this
variable.  Other than the zsh/terminfo module, zsh is dealing with
termcap or termcap emulation.

On the other hand, zsh does react when the TERM parameter is changed.
I have zsh linked against ncurses, which knows about TERMINFO even though
zsh doesn't, and if I export TERMINFO, then change TERM, it will happily
find the terminfo definitions in $TERMINFO.

Thus, I think you are either not exporting TERMINFO to the environment
or the library which is providing zsh with tgetent() and friends
doesn't care about that variable.

We perhaps ought to mention that zsh error message in the FAQ.

Have you done export TERMCAP=~/etc/termcap so that it can find that
then?

I recently had problems with zsh on a Linux box understanding iris-ansi
terms which was solved by fixing the termcap entry so I'd assume it
isn't using terminfo.

ahh ok - i had exported all 3, and even in the right order, but i was
exporting them all at once; ie:
export TERMCAP TERMINFO TERM
doing:
export TERMCAP=~/etc/termcap
and so on works great.  otherwise login shells weren't working properly
- just subsequent shells.

On all versions of RedHat linux at least up to 6.2, zsh uses termcap
unless configured with --enable-curses-terminfo.  I expect this is true
on several other linux distributions as well (except probably Debian).

one more dumb question.  if i want to link zsh to the copy of ncurses in
my home directory instead of the machine's, but i still want to use the
remainder of the machine's include files, how do i need to configure
zsh?

i have ncurses 5.2 installed in ~/include and ~/lib with the terminfo
stuff in ~/share/terminfo
