dnl Curses detection routines: Munged from Midnight commander's configure.in
dnl Curses detection: Munged from Midnight Commander's configure.in
dnl
dnl Called after AC_CHECK_CURSES after AC_PROG_CC
dnl What it does:
dnl =============
dnl
dnl Will adjust CURSES_INCLUDEDIR, CURSES_LIBS, and possibly CFLAGS
dnl Also do AC_SUBST on CURSES_INCLUDEDIR and CURSES_LIBS
dnl - Determine which version of curses is installed on your system
dnl and set the -I/-L/-l compiler entries and add a few preprocessor
dnl symbols
dnl - Do an AC_SUBST on the CURSES_INCLUDEDIR and CURSES_LIBS so that
dnl @CURSES_INCLUDEDIR@ and @CURSES_LIBS@ will be available in
dnl Makefile.in's
dnl - Modify the following configure variables (these are the only
dnl curses.m4 variables you can access from within configure.in)
dnl CURSES_INCLUDEDIR - contains -I's and possibly -DRENAMED_CURSES if
dnl an ncurses.h that's been renamed to curses.h
dnl is found.
dnl CURSES_LIBS - sets -L and -l's appropriately
dnl CFLAGS - if --with-sco, add -D_SVID3
dnl has_curses - exports result of tests to rest of configure
dnl
dnl Add this to acconfig.h:
dnl Usage:
dnl ======
dnl 1) Add lines indicated below to acconfig.h
dnl 2) call AC_CHECK_CURSES after AC_PROG_CC in your configure.in
dnl 3) Instead of #include <curses.h> you should use the following to
dnl properly locate ncurses or curses header file
dnl
dnl /*=== Curses variables swiped from Midnight commander's config ===*/
dnl
dnl #if defined(USE_NCURSES) && !defined(RENAMED_NCURSES)
dnl #include <ncurses.h>
dnl #else
dnl #include <curses.h>
dnl #endif
dnl
dnl 4) Make sure to add @CURSES_INCLUDEDIR@ to your preprocessor flags
dnl 5) Make sure to add @CURSES_LIBS@ to your linker flags or LIBS
dnl
dnl Notes with automake:
dnl - call AM_CONDITIONAL(HAS_CURSES, test "$has_curses" = true) from
dnl configure.in
dnl - your Makefile.am can look something like this
dnl -----------------------------------------------
dnl INCLUDES= blah blah blah $(CURSES_INCLUDEDIR)
dnl if HAS_CURSES
dnl CURSES_TARGETS=name_of_curses_prog
dnl endif
dnl bin_PROGRAMS = other_programs $(CURSES_TARGETS)
dnl other_programs_SOURCES = blah blah blah
dnl name_of_curses_prog_SOURCES = blah blah blah
dnl other_programs_LDADD = blah
dnl name_of_curses_prog_LDADD = blah $(CURSES_LIBS)
dnl -----------------------------------------------
dnl
dnl
