In particular, the Panel, Menu and Form +# libraries are searched, along with their header files. These macros +# depend on AX_WITH_CURSES. +# +# The following preprocessor symbols may be defined by these macros: +# +# By AX_WITH_CURSES_PANEL: +# +# HAVE_PANEL - if the Panel library is present +# HAVE_PANEL_H - if is present and should be used +# HAVE_NCURSES_PANEL_H - if should be used +# HAVE_NCURSESW_PANEL_H - if should be used +# +# By AX_WITH_CURSES_MENU: +# +# HAVE_MENU - if the Menu library is present +# HAVE_MENU_H - if is present and should be used +# HAVE_NCURSES_MENU_H - if should be used +# HAVE_NCURSESW_MENU_H - if should be used +# +# By AX_WITH_CURSES_FORM: +# +# HAVE_FORM - if the Form library is present +# HAVE_FORM_H - if is present and should be used +# HAVE_NCURSES_FORM_H - if should be used +# HAVE_NCURSESW_FORM_H - if should be used +# +# The following output variables may be defined by these macros; these are +# precious and may be overridden on the ./configure command line: +# +# PANEL_LIB - library to add to xxx_LDADD before CURSES_LIB +# MENU_LIB - library to add to xxx_LDADD before CURSES_LIB +# FORM_LIB - library to add to xxx_LDADD before CURSES_LIB +# +# These libraries are NOT added to LIBS by default. You need to add them +# to the appropriate xxx_LDADD line in your Makefile.am in front of the +# equivalent CURSES_LIB incantation. For example: +# +# prog_LDADD = @PANEL_LIB@ @CURSES_LIB@ +# +# If one of the xxx_LIB variables is set on the configure command line +# (such as by running "./configure PANEL_LIB=-lmypanel"), then the header +# file searched must NOT contain a subpath. In this case, in other words, +# only would be searched for. The user may use the CPPFLAGS +# precious variable to override the standard #include search path. +# +# The following shell variables may be defined by these macros: +# +# ax_cv_panel - set to "yes" if Panels library is present +# ax_cv_menu - set to "yes" if Menu library is present +# ax_cv_form - set to "yes" if Form library is present +# +# These variables can be used in your configure.ac to determine whether a +# library you require is actually present. For example: +# +# AX_WITH_CURSES +# if test "x$ax_cv_curses" != xyes; then +# AC_MSG_ERROR([requires a SysV or X/Open-compatible Curses library]) +# fi +# AX_WITH_CURSES_PANEL +# if test "x$ax_cv_panel" != xyes; then +# AC_MSG_ERROR([requires the Curses Panel library]) +# fi +# +# To use the HAVE_xxx_H preprocessor symbols, insert the following into +# your system.h (or equivalent) header file: +# +# For AX_WITH_CURSES_PANEL: +# +# #if defined(HAVE_NCURSESW_PANEL_H) +# # include +# #elif defined(HAVE_NCURSES_PANEL_H) +# # include +# #elif defined(HAVE_PANEL_H) +# # include +# #else +# # error "SysV-compatible Curses Panel header file required" +# #endif +# +# For AX_WITH_CURSES_MENU: +# +# #if defined(HAVE_NCURSESW_MENU_H) +# # include +# #elif defined(HAVE_NCURSES_MENU_H) +# # include +# #elif defined(HAVE_MENU_H) +# # include +# #else +# # error "SysV-compatible Curses Menu header file required" +# #endif +# +# For AX_WITH_CURSES_FORM: +# +# #if defined(HAVE_NCURSESW_FORM_H) +# # include +# #elif defined(HAVE_NCURSES_FORM_H) +# # include +# #elif defined(HAVE_FORM_H) +# # include +# #else +# # error "SysV-compatible Curses Form header file required" +# #endif +# +# LICENSE +# +# Copyright (c) 2011 John Zaitseff +# +# This program is free software: you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by the +# Free Software Foundation, either version 3 of the License, or (at your +# option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
