Build gdb without installing termcap?

Build gdb without installing termcap?

[Michael Snyder]

This is something I've run up against before...

Often when I try to build gdb on a new host, it fails because configure
can't find libtermcap (which I guess it wants both for TUI and
readline).  I usually end up building and installing libtermcap from
sources, as root, into the system directory, but if it's someone else's
machine I'd rather not do that.

Is there some configure option that I can use to make it find a local
build or install of libtermcap?

As far as I know, there is not. The reason why I think there is not,
is because I remember us discussing many many years ago adding the
possibility of specifying the location where the curses library (and
headers) is installed; something a-la --with-libexpat-prefix.

I don't think there is anything specific to termcap, but you should be
able to set CPPFLAGS and LDFLAGS on the configure command line.

I can't remember the details, but I sort of remember that we couldn't
make it work just using these variables... Maybe I'm wrong, it was
a while ago.

I was going to point out the same thing.  We can have --with-for,
--with-foo-include, --with-foo-lib for every library used by GDB, but
unlesss there is some other magic that needs to be done this only
complicates the autoconf script and makes the ./configure --help
output even more unwieldy.

Yeah, I remember now too:

I wonder whether Ralf's recent auto* upgrade helped with this.  I'm
guessing not but I didn't check.  The reversion message sheds some light
on the problem:
