If found, defines -# `HAVE_LIBREADLINE'. If the found library has the `add_history' function, -# sets also `HAVE_READLINE_HISTORY'. Also checks for the locations of the -# necessary include files and sets `HAVE_READLINE_H' or -# `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or -# 'HAVE_HISTORY_H' if the corresponding include files exists. -# -# The libraries that may be readline compatible are `libedit', -# `libeditline' and `libreadline'. Sometimes we need to link a termcap -# library for readline to work, this macro tests these cases too by trying -# to link with `libtermcap', `libcurses' or `libncurses' before giving up. -# -# Here is an example of how to use the information provided by this macro -# to perform the necessary includes or declarations in a C file: -# -# #ifdef HAVE_LIBREADLINE -# # if defined(HAVE_READLINE_READLINE_H) -# # include <readline/readline.h> -# # elif defined(HAVE_READLINE_H) -# # include <readline.h> -# # else /* !defined(HAVE_READLINE_H) */ -# extern char *readline (); -# # endif /* !defined(HAVE_READLINE_H) */ -# char *cmdline = NULL; -# #else /* !defined(HAVE_READLINE_READLINE_H) */ -# /* no readline */ -# #endif /* HAVE_LIBREADLINE */ -# -# #ifdef HAVE_READLINE_HISTORY -# # if defined(HAVE_READLINE_HISTORY_H) -# # include <readline/history.h> -# # elif defined(HAVE_HISTORY_H) -# # include <history.h> -# # else /* !defined(HAVE_HISTORY_H) */ -# extern void add_history (); -# extern int write_history (); -# extern int read_history (); -# # endif /* defined(HAVE_READLINE_HISTORY_H) */ -# /* no history */ -# #endif /* HAVE_READLINE_HISTORY */ -# -# LAST MODIFICATION -# -# 2008-04-12 -# -# COPYLEFT -# -# Copyright (c) 2008 Ville Laurikari <vl@iki.fi> -# -# Copying and distribution of this file, with or without modification, are -# permitted in any medium without royalty provided the copyright notice -# and this notice are preserved. - -AC_DEFUN([VL_LIB_READLINE], [ - AC_CACHE_CHECK([for a readline compatible library], - vl_cv_lib_readline, [ - ORIG_LIBS="$LIBS" - for readline_lib in readline edit editline; do - for termcap_lib in "" termcap curses ncurses; do - if test -z "$termcap_lib"; then - TRY_LIB="-l$readline_lib" - else - TRY_LIB="-l$readline_lib -l$termcap_lib" - fi - LIBS="$ORIG_LIBS $TRY_LIB" - AC_TRY_LINK_FUNC(readline, vl_cv_lib_readline="$TRY_LIB") - if test -n "$vl_cv_lib_readline"; then - break - fi - done - if test -n "$vl_cv_lib_readline"; then - break - fi - done - if test -z "$vl_cv_lib_readline"; then - vl_cv_lib_readline="no" - LIBS="$ORIG_LIBS" - fi - ]) - - if test "$vl_cv_lib_readline" != "no"; then - AC_DEFINE(HAVE_LIBREADLINE, 1, - [Define if you have a readline compatible library]) - AC_CHECK_HEADERS(readline.h readline/readline.h) - AC_CACHE_CHECK([whether readline supports history], - vl_cv_lib_readline_history, [ - vl_cv_lib_readline_history="no" - AC_TRY_LINK_FUNC(add_history, vl_cv_lib_readline_history="yes") - ]) - if test "$vl_cv_lib_readline_history" = "yes"; then - AC_DEFINE(HAVE_READLINE_HISTORY, 1, - [Define if your readline library has \`add_history']) - AC_CHECK_HEADERS(history.h readline/history.h) - fi - fi -])dnl - |
