Re: LFTP: Cygwin and setupterm

[Charles Wilson <cwilson at ece dot gatech dot edu>]

This thread has a lot of misinformation and just plain confusion.

For starters, term.h != termcap.h.  Some messages in this thread talk 
about term.h, others about termcap.h -- and seem to mean one when 
they're talking about the other.  Sigh.

Also, /usr/include/termcap.h is NOT the ncurses version (on a stock 
cygwin system).  The ncurses termcap compatibility header file is 
/usr/include/ncurses/termcapn.h (note the extra 'n')

No, the standard ncurses package doesn't put a term.h -> ncurses/term.h 
symlink.  It probably should; my linux box includes these symlinks that 
the ncurses cygwin package doesn't:
  /usr/include/term.h -> ncurses/term.h
  /usr/include/eti.h  -> ncurses/eti.h
For now, do it yourself.  I've added this change to my ncurses TODO 
list, so the next ncurses release will do this for you.

As far as Frederic's problem goes, I'd create the new symlinks, and 
re-run configure (after deleting config.cache).  Hopefully that will 
make the changes to lftp_tinfo.cc unnecessary.

If you want to use ncurses as a complete replacement for libtermcap 
(when compiling; this procedure will NOT change the runtime behavior of 
already-compiled programs), then you need to:
  rename
    /usr/include/ncurses/termcapn.h to
    /usr/include/ncurses/termcap.h
Do NOT copy it into /usr/include -- the "real" termcap.h should live 
there.  [DON'T DO THIS: You'd want to uninstall the termcap package BUT 
YOU CAN'T].  The problem is, the termcap package includes the header and 
library *as well as* /etc/termcap.   You want to keep /etc/termcap; so 
you must manually delete /usr/include/termcap.h, /usr/lib/libtermcap.a, 
and /usr/man/man3/termcap.3.   And they'll reappear the next time you 
update the termcap package.

Once you've done all this, if the package you are compiling is set up 
properly, it will see termcap.h in /usr/include/ncurses, and use it (and 
will automatically link using -lcurses or -lncurses instead of 
-ltermcap.  But only if your autoconfigury stuff is handled properly. 
If it is not, then it's a bug in the package you're trying to compile -- 
go talk to them about it.
