13 # These macros try to find additional libraries that often come with
14 # SysV-compatible Curses. In particular, the Panel, Menu and Form
15 # libraries are searched, along with their header files. These macros
16 # depend on AX_WITH_CURSES.
18 # The following preprocessor symbols may be defined by these macros:
20 # By AX_WITH_CURSES_PANEL:
22 # HAVE_PANEL - if the Panel library is present
23 # HAVE_PANEL_H - if <panel.h> is present and should be used
24 # HAVE_NCURSES_PANEL_H - if <ncurses/panel.h> should be used
25 # HAVE_NCURSESW_PANEL_H - if <ncursesw/panel.h> should be used
27 # By AX_WITH_CURSES_MENU:
29 # HAVE_MENU - if the Menu library is present
30 # HAVE_MENU_H - if <menu.h> is present and should be used
31 # HAVE_NCURSES_MENU_H - if <ncurses/menu.h> should be used
32 # HAVE_NCURSESW_MENU_H - if <ncursesw/menu.h> should be used
34 # By AX_WITH_CURSES_FORM:
36 # HAVE_FORM - if the Form library is present
37 # HAVE_FORM_H - if <form.h> is present and should be used
38 # HAVE_NCURSES_FORM_H - if <ncurses/form.h> should be used
39 # HAVE_NCURSESW_FORM_H - if <ncursesw/form.h> should be used
41 # The following output variables may be defined by these macros; these are
42 # precious and may be overridden on the ./configure command line:
44 # PANEL_LIBS - library to add to xxx_LDADD before CURSES_LIBS
45 # MENU_LIBS - library to add to xxx_LDADD before CURSES_LIBS
46 # FORM_LIBS - library to add to xxx_LDADD before CURSES_LIBS
48 # In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and
49 # FORM_LIB were defined. These have been renamed, in keeping with the
50 # variable scheme of PKG_CHECK_MODULES, which should eventually supersede
51 # the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. These libraries
52 # are NOT added to LIBS by default. You need to add them to the
53 # appropriate xxx_LDADD line in your Makefile.am in front of the
54 # equivalent CURSES_LIBS incantation. For example:
56 # prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@
58 # If one of the xxx_LIBS variables is set on the configure command line
59 # (such as by running "./configure PANEL_LIBS=-lmypanel"), then the header
60 # file searched must NOT contain a subpath. In this case, in other words,
61 # only <panel.h> would be searched for. The user may use the CPPFLAGS
62 # precious variable to override the standard #include search path.
64 # The following shell variables may be defined by these macros:
66 # ax_cv_panel - set to "yes" if Panels library is present
67 # ax_cv_menu - set to "yes" if Menu library is present
68 # ax_cv_form - set to "yes" if Form library is present
70 # These variables can be used in your configure.ac to determine whether a
71 # library you require is actually present. For example:
74 # if test "x$ax_cv_curses" != xyes; then
75 # AC_MSG_ERROR([requires a SysV or X/Open-compatible Curses library])
77 # AX_WITH_CURSES_PANEL
78 # if test "x$ax_cv_panel" != xyes; then
79 # AC_MSG_ERROR([requires the Curses Panel library])
82 # To use the HAVE_xxx_H preprocessor symbols, insert the following into
83 # your system.h (or equivalent) header file:
85 # For AX_WITH_CURSES_PANEL:
87 # #if defined HAVE_NCURSESW_PANEL_H
88 # # include <ncursesw/panel.h>
89 # #elif defined HAVE_NCURSES_PANEL_H
90 # # include <ncurses/panel.h>
91 # #elif defined HAVE_PANEL_H
94 # # error "SysV-compatible Curses Panel header file required"
97 # For AX_WITH_CURSES_MENU:
99 # #if defined HAVE_NCURSESW_MENU_H
100 # # include <ncursesw/menu.h>
101 # #elif defined HAVE_NCURSES_MENU_H
102 # # include <ncurses/menu.h>
103 # #elif defined HAVE_MENU_H
106 # # error "SysV-compatible Curses Menu header file required"
109 # For AX_WITH_CURSES_FORM:
111 # #if defined HAVE_NCURSESW_FORM_H
112 # # include <ncursesw/form.h>
113 # #elif defined HAVE_NCURSES_FORM_H
114 # # include <ncurses/form.h>
115 # #elif defined HAVE_FORM_H
118 # # error "SysV-compatible Curses Form header file required"
