Hi all;
Is there a way to force gdb to build against ncurses, not ncursesw,
even if ncursesw headers/libraries do exist on the system?
The problem with ncursesw is that not all distributions put it onto the
system by default (everyone has ncurses by default) so if I compile GDB
against ncursesw then I have to get everyone to install extra packages.
There's really no need (that I can see) for ncursesw since we just
always uses utf8 all the time for everything.
But, I can't find any configure option or even cache setting I can use
to force the use of ncurses.
Cheers!

I should clarify that by this I mean, _I_ (and the folks I work with)
have no need for it in our environment: I'm not suggesting everyone
should use utf8 and no one has any need for ncursesw.

Looking at configure.ac, the library is chosen using this line:
AC_SEARCH_LIBS(waddstr, [ncursesw ncurses cursesX curses])
Then, looking at my config.cache, I see this line:
ac_cv_search_waddstr=${ac_cv_search_waddstr=-lncursesw}
So I suppose that if you pass ac_cv_search_waddstr=-lncurses to
configure, it will just use that instead of probing.

Seems a bit dodgy. Also, there are other places where ncursesw is
checked before ncurses:
AC_SEARCH_LIBS(tgetent, [termcap tinfow tinfo curses ncursesw ncurses])
...
AC_CHECK_HEADERS(curses.h cursesX.h ncurses.h ncursesw/ncurses.h ncurses/ncurses.h ncurses/term.h)
For my system luckily I don't need tgetent. And, I'm not 100% sure if
the HAVE_NCURSESW_* config options will be set properly in this
situation.
It would be nice if there were a configure option to either ignore
ncursesw, or else to specifically set the library and headers location.
Oh well, I will hack at it; thanks!
