Synopsis

AX_WITH_CURSES_PANEL
AX_WITH_CURSES_MENU
AX_WITH_CURSES_FORM

Description

These macros try to find additional libraries that often come with SysV-compatible Curses. 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 <panel.h> is present and should be used
  HAVE_NCURSES_PANEL_H    - if <ncurses/panel.h> should be used
  HAVE_NCURSESW_PANEL_H   - if <ncursesw/panel.h> should be used

  By AX_WITH_CURSES_MENU:

  HAVE_MENU               - if the Menu library is present
  HAVE_MENU_H             - if <menu.h> is present and should be used
  HAVE_NCURSES_MENU_H     - if <ncurses/menu.h> should be used
  HAVE_NCURSESW_MENU_H    - if <ncursesw/menu.h> should be used

  By AX_WITH_CURSES_FORM:

  HAVE_FORM               - if the Form library is present
  HAVE_FORM_H             - if <form.h> is present and should be used
  HAVE_NCURSES_FORM_H     - if <ncurses/form.h> should be used
  HAVE_NCURSESW_FORM_H    - if <ncursesw/form.h> 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_LIBS   - library to add to xxx_LDADD before CURSES_LIBS
  MENU_LIBS    - library to add to xxx_LDADD before CURSES_LIBS
  FORM_LIBS    - library to add to xxx_LDADD before CURSES_LIBS

In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and FORM_LIB were defined. These have been renamed, in keeping with the variable scheme of PKG_CHECK_MODULES, which should eventually supersede the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. 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_LIBS incantation. For example:

  prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@

If one of the xxx_LIBS variables is set on the configure command line (such as by running "./configure PANEL_LIBS=-lmypanel"), then the header file searched must NOT contain a subpath. In this case, in other words, only <panel.h> 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 <ncursesw/panel.h>
  #elif defined HAVE_NCURSES_PANEL_H
  #  include <ncurses/panel.h>
  #elif defined HAVE_PANEL_H
  #  include <panel.h>
  #else
  #  error "SysV-compatible Curses Panel header file required"
  #endif

  For AX_WITH_CURSES_MENU:

  #if defined HAVE_NCURSESW_MENU_H
  #  include <ncursesw/menu.h>
  #elif defined HAVE_NCURSES_MENU_H
  #  include <ncurses/menu.h>
  #elif defined HAVE_MENU_H
  #  include <menu.h>
  #else
  #  error "SysV-compatible Curses Menu header file required"
  #endif

  For AX_WITH_CURSES_FORM:

  #if defined HAVE_NCURSESW_FORM_H
  #  include <ncursesw/form.h>
  #elif defined HAVE_NCURSES_FORM_H
  #  include <ncurses/form.h>
  #elif defined HAVE_FORM_H
  #  include <form.h>
  #else
  #  error "SysV-compatible Curses Form header file required"
  #endif
