dnl Curses detection: Munged from Midnight Commander's configure.in dnl dnl What it does: dnl ============= dnl 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 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 #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 $(CURSES_LIBS) dnl ----------------------------------------------- dnl dnl dnl The following lines should be added to acconfig.h: dnl ================================================== dnl dnl /*=== Curses version detection defines ===*/ dnl /* Found some version of curses that we're going to use */ dnl #undef HAS_CURSES dnl dnl /* Use SunOS SysV curses? */ dnl #undef USE_SUNOS_CURSES dnl dnl /* Use old BSD curses - not used right now */ dnl #undef USE_BSD_CURSES dnl dnl /* Use SystemV curses? */ dnl #undef USE_SYSV_CURSES dnl dnl /* Use Ncurses? */ dnl #undef USE_NCURSES dnl dnl /* If you Curses does not have color define this one */ dnl #undef NO_COLOR_CURSES dnl dnl /* Define if you want to turn on SCO-specific code */ dnl #undef SCO_FLAVOR dnl dnl /* Set to reflect version of ncurses * dnl * 0 = version 1.* dnl * 1 = version 1.9.9g dnl * 2 = version 4.0/4.1 */ dnl #undef NCURSES_970530 dnl dnl /*=== End new stuff for acconfig.h ===*/ dnl AC_DEFUN([AC_CHECK_CURSES],[ search_ncurses=true screen_manager="" has_curses=false CFLAGS=${CFLAGS--O} AC_SUBST(CURSES_LIBS) AC_SUBST(CURSES_INCLUDEDIR) AC_ARG_WITH(sco, [ --with-sco Use this to turn on SCO-specific code],[ if test x$withval = xyes;
