AX_WITH_CURSES_PANEL AX_WITH_CURSES_MENU AX_WITH_CURSES_FORM
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:
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
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
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_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 <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:
#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
#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
#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
