I see - but this is not the root cause. In lynx, LYStrings.c includes
LYStrings.h, which includes LYCurses.h, which _does_ include a properly
ifdef'd version of term.h -- for portable applications.
The bug report says that he is trying to build with ncursesw.
The header files for ncurses and ncursesw are "mostly" compatible,
allowing an application which compiles against ncurses to be compiled
against ncursesw (the reverse is not necessarily true: although "term.h"
is identical, ncurses.h is not).
I think that the problem (and ultimate solution) lies in the ncursesw
port, in which I see two problems:
a) ncursesw5-config is not installed
b) the header files are incomplete, with /usr/pkg/include/ncursesw
containing only ncurses.h
A portable application will not assume this directory layout.
Instead, it will make one of these assumptions:
1) All of the curses header files can be included like this:
#include <curses.h>
#include <term.h>
#include <unctrl.h>
2) All of the ncurses header files can be included like this:
#include <ncurses/curses.h>
#include <ncurses/term.h>
#include <ncurses/unctrl.h>
3) All of the ncurses header files can be included like this:
#include <ncursesw/curses.h>
#include <ncursesw/term.h>
#include <ncursesw/unctrl.h>
