# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_with_curses.html # =========================================================================== # # SYNOPSIS # # AX_WITH_CURSES # # DESCRIPTION # # This macro checks whether a SysV or X/Open-compatible Curses library is # present, along with the associated header file. The NcursesW # (wide-character) library is searched for first, followed by Ncurses, # then the system-default plain Curses. The first library found is the # one returned. # # The following options are understood: --with-ncursesw, --with-ncurses, # --without-ncursesw, --without-ncurses. The "--with" options force the # macro to use that particular library, terminating with an error if not # found. The "--without" options simply skip the check for that library. # The effect on the search pattern is: # # (no options) - NcursesW, Ncurses, Curses # --with-ncurses --with-ncursesw - NcursesW only [*] # --without-ncurses --with-ncursesw - NcursesW only [*] # --with-ncursesw - NcursesW only [*] # --with-ncurses --without-ncursesw - Ncurses only [*] # --with-ncurses - NcursesW, Ncurses [**] # --without-ncurses --without-ncursesw - Curses only # --without-ncursesw - Ncurses, Curses # --without-ncurses - NcursesW, Curses # # [*] If the library is not found, abort the configure script. # # [**] If the second library (Ncurses) is not found, abort configure. # # The following preprocessor symbols may be defined by this macro if the # appropriate conditions are met: # # HAVE_CURSES - if any SysV or X/Open Curses library found # HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions # HAVE_CURSES_COLOR - if library supports color (enhanced functions) # HAVE_CURSES_OBSOLETE - if library supports certain obsolete features # HAVE_NCURSESW - if NcursesW (wide char) library is to be used # HAVE_NCURSES - if the Ncurses library is to be used # # HAVE_CURSES_H - if is present and should be used # HAVE_NCURSESW_H - if should be used # HAVE_NCURSES_H - if should be used # HAVE_NCURSESW_CURSES_H - if should be used # HAVE_NCURSES_CURSES_H - if should be used # # (These preprocessor symbols are discussed later in this document.) # # The following output variable is defined by this macro; it is precious # and may be overridden on the ./configure command line: # # CURSES_LIB - library to add to xxx_LDADD # # The library listed in CURSES_LIB is NOT added to LIBS by default. You # need to add CURSES_LIB to the appropriate xxx_LDADD line in your # Makefile.am. For example: # # prog_LDADD = @CURSES_LIB@ # # If CURSES_LIB is set on the configure command line (such as by running # "./configure CURSES_LIB=-lmycurses"), then the only header searched for # is . The user may use the CPPFLAGS precious variable to # override the standard #include search path. If the user needs to # specify an alternative path for a library (such as for a non-standard # NcurseW), the user should use the LDFLAGS variable. # # The following shell variables may be defined by this macro: # # ax_cv_curses - set to "yes" if any Curses library found # ax_cv_curses_enhanced - set to "yes" if Enhanced functions present # ax_cv_curses_color - set to "yes" if color functions present # ax_cv_curses_obsolete - set to "yes" if obsolete features present # # ax_cv_ncursesw - set to "yes" if NcursesW library found # ax_cv_ncurses - set to "yes" if Ncurses library found # ax_cv_plaincurses - set to "yes" if plain Curses library found # ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no" # # These variables can be used in your configure.ac to determine the level # of support you need from the Curses library. For example, if you must # have either Ncurses or NcursesW, you could include: # # AX_WITH_CURSES # if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then # AX_MSG_ERROR([requires either NcursesW or Ncurses library]) # fi # # If any Curses library will do (but one must be present and must support # color), you could use: # # AX_WITH_CURSES # if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then # AC_MSG_ERROR([requires an X/Open-compatible Curses library with color]) # fi # # Certain preprocessor symbols and shell variables defined by this macro # can be used to determine various features of the Curses library. In # particular, HAVE_CURSES and ax_cv_curses are defined if the Curses # library found conforms to the traditional SysV and/or X/Open Base Curses # definition. Any working Curses library conforms to this level. # # HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the # library supports the X/Open Enhanced Curses definition. In particular, # the wide-character types attr_t, cchar_t and wint_t, the functions # wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES # are checked. The Ncurses library does NOT conform to this definition, # although NcursesW does. # # HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library # supports color functions and macros such as COLOR_PAIR, A_COLOR, # COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the # X/Open Base Curses definition, but are part of the Enhanced set of # functions. The Ncurses library DOES support these functions, as does # NcursesW. # # HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the # library supports certain features present in SysV and BSD Curses but not # defined in the X/Open definition. In particular, the functions # getattrs(), getcurx() and getmaxx() are checked. # # To use the HAVE_xxx_H preprocessor symbols, insert the following into # your system.h (or equivalent) header file: # # #if defined(HAVE_NCURSESW_CURSES_H) # # include # #elif defined(HAVE_NCURSESW_H) # # include # #elif defined(HAVE_NCURSES_CURSES_H) # # include # #elif defined(HAVE_NCURSES_H) # # include # #elif defined(HAVE_CURSES_H) # # include # #else # # error "SysV or X/Open-compatible Curses header file required" # #endif # # For previous users of this macro: you should not need to change anything # in your configure.ac or Makefile.am, as the previous (serial 10) # semantics are still valid. However, you should update your system.h (or # equivalent) header file to the fragment shown above. You are encouraged # also to make use of the extended functionality provided by this version # of AX_WITH_CURSES, as well as in the additional macros # AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM. # # LICENSE # # Copyright (c) 2009 Mark Pulford # Copyright (c) 2009 Damian Pietras # Copyright (c) 2011 Reuben Thomas # 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.
