[Bug 1786617] Re: setupterm doesn't find terminfo entry in non-standard database location

[Kovid Goyal]

Not to mention that if symlinking the compiled terminfo into
/usr/share/terminfo fixes the problem, then the problem cannot be in the
format of the compiled database.

Title:
  setupterm doesn't find terminfo entry in non-standard database
  location

Status in ncurses package in Ubuntu:
  New

Bug description:
  My terminal emulator (Kitty) installs its terminfo entry to:

  /usr/local/lib/kitty/terminfo/x/xterm-kitty

  But it also registers /usr/local/lib/kitty/terminfo/ as a terminfo
  database:

  % infocmp -D
  /usr/local/lib/kitty/terminfo
  /etc/terminfo
  /lib/terminfo
  /usr/share/terminfo

  I use tmux, which uses setupterm:
  https://github.com/tmux/tmux/blob/b2a2c3a1e90756313b6709905f189934123f85ed
  /tty-term.c#L412

  setupterm sets an error code unless I symlink the terminfo def to a
  traditional location:

  sudo ln -s /usr/local/lib/kitty/terminfo/x/xterm-kitty
  /usr/share/terminfo/x/xterm-kitty

  This stops the problem. setupterm is presumably not searching all
  database locations.

  I am not the developer of tmux, he directed me here to log the issue.

  See https://github.com/tmux/tmux/issues/1433 for the original bug
  report.
