5: # SYNOPSIS

7: # AX_WITH_CURSES
8: #
9: # DESCRIPTION
10: #
11: # This macro checks whether a SysV or X/Open-compatible Curses library is
12: # present, along with the associated header file. The NcursesW
13: # (wide-character) library is searched for first, followed by Ncurses,
14: # then the system-default plain Curses. The first library found is the
15: # one returned.
16: #
17: # The following options are understood: --with-ncursesw, --with-ncurses,
18: # --without-ncursesw, --without-ncurses. The "--with" options force the
19: # macro to use that particular library, terminating with an error if not
20: # found. The "--without" options simply skip the check for that library.
21: # The effect on the search pattern is:
22: #
23: # (no options) - NcursesW, Ncurses, Curses
24: # --with-ncurses --with-ncursesw - NcursesW only [*]
25: # --without-ncurses --with-ncursesw - NcursesW only [*]
26: # --with-ncursesw - NcursesW only [*]
27: # --with-ncurses --without-ncursesw - Ncurses only [*]
28: # --with-ncurses - NcursesW, Ncurses [**]
29: # --without-ncurses --without-ncursesw - Curses only
30: # --without-ncursesw - Ncurses, Curses
31: # --without-ncurses - NcursesW, Curses
32: #
33: # [*] If the library is not found, abort the configure script.
34: #
35: # [**] If the second library (Ncurses) is not found, abort configure.
36: #
37: # The following preprocessor symbols may be defined by this macro if the
38: # appropriate conditions are met:
39: #
40: # HAVE_CURSES - if any SysV or X/Open Curses library found
41: # HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions
42: # HAVE_CURSES_COLOR - if library supports color (enhanced functions)
43: # HAVE_CURSES_OBSOLETE - if library supports certain obsolete features
44: # HAVE_NCURSESW - if NcursesW (wide char) library is to be used
45: # HAVE_NCURSES - if the Ncurses library is to be used
46: #
47: # HAVE_CURSES_H - if <curses.h> is present and should be used
48: # HAVE_NCURSESW_H - if <ncursesw.h> should be used
49: # HAVE_NCURSES_H - if <ncurses.h> should be used
50: # HAVE_NCURSESW_CURSES_H - if <ncursesw/curses.h> should be used
51: # HAVE_NCURSES_CURSES_H - if <ncurses/curses.h> should be used
52: #
53: # (These preprocessor symbols are discussed later in this document.)
54: #
55: # The following output variable is defined by this macro; it is precious
56: # and may be overridden on the ./configure command line:
57: #
58: # CURSES_LIB - library to add to xxx_LDADD
59: #
60: # The library listed in CURSES_LIB is NOT added to LIBS by default. You
61: # need to add CURSES_LIB to the appropriate xxx_LDADD line in your
62: # Makefile.am. For example:
63: #
64: # prog_LDADD = @CURSES_LIB@
65: #
66: # If CURSES_LIB is set on the configure command line (such as by running
67: # "./configure CURSES_LIB=-lmycurses"), then the only header searched for
68: # is <curses.h>. The user may use the CPPFLAGS precious variable to
69: # override the standard #include search path. If the user needs to
70: # specify an alternative path for a library (such as for a non-standard
71: # NcurseW), the user should use the LDFLAGS variable.
72: #
73: # The following shell variables may be defined by this macro:
74: #
75: # ax_cv_curses - set to "yes" if any Curses library found
76: # ax_cv_curses_enhanced - set to "yes" if Enhanced functions present
77: # ax_cv_curses_color - set to "yes" if color functions present
78: # ax_cv_curses_obsolete - set to "yes" if obsolete features present
79: #
80: # ax_cv_ncursesw - set to "yes" if NcursesW library found
81: # ax_cv_ncurses - set to "yes" if Ncurses library found
82: # ax_cv_plaincurses - set to "yes" if plain Curses library found
83: # ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no"
84: #
85: # These variables can be used in your configure.ac to determine the level
86: # of support you need from the Curses library. For example, if you must
87: # have either Ncurses or NcursesW, you could include:
88: #
89: # AX_WITH_CURSES
90: # if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
91: # AX_MSG_ERROR([requires either NcursesW or Ncurses library])
92: # fi
93: #
94: # If any Curses library will do (but one must be present and must support
95: # color), you could use:
96: #
97: # AX_WITH_CURSES
98: # if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
99: # AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
100: # fi
101: #
102: # Certain preprocessor symbols and shell variables defined by this macro
103: # can be used to determine various features of the Curses library. In
104: # particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
105: # library found conforms to the traditional SysV and/or X/Open Base Curses
106: # definition. Any working Curses library conforms to this level.
107: #
108: # HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
109: # library supports the X/Open Enhanced Curses definition. In particular,
110: # the wide-character types attr_t, cchar_t and wint_t, the functions
111: # wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
112: # are checked. The Ncurses library does NOT conform to this definition,
113: # although NcursesW does.
114: #
115: # HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
116: # supports color functions and macros such as COLOR_PAIR, A_COLOR,
117: # COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the
118: # X/Open Base Curses definition, but are part of the Enhanced set of
119: # functions. The Ncurses library DOES support these functions, as does
120: # NcursesW.
121: #
122: # HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
123: # library supports certain features present in SysV and BSD Curses but not
124: # defined in the X/Open definition. In particular, the functions
125: # getattrs(), getcurx() and getmaxx() are checked.
126: #
127: # To use the HAVE_xxx_H preprocessor symbols, insert the following into
128: # your system.h (or equivalent) header file:
129: #
130: # #if defined HAVE_NCURSESW_CURSES_H
131: # # include <ncursesw/curses.h>
132: # #elif defined HAVE_NCURSESW_H
133: # # include <ncursesw.h>
134: # #elif defined HAVE_NCURSES_CURSES_H
135: # # include <ncurses/curses.h>
136: # #elif defined HAVE_NCURSES_H
137: # # include <ncurses.h>
138: # #elif defined HAVE_CURSES_H
139: # # include <curses.h>
140: # #else
141: # # error "SysV or X/Open-compatible Curses header file required"
142: # #endif
143: #
144: # For previous users of this macro: you should not need to change anything
145: # in your configure.ac or Makefile.am, as the previous (serial 10)
146: # semantics are still valid. However, you should update your system.h (or
147: # equivalent) header file to the fragment shown above. You are encouraged
148: # also to make use of the extended functionality provided by this version
149: # of AX_WITH_CURSES, as well as in the additional macros
150: # AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.
