1 dnl Curses detection: Munged from Midnight Commander's configure.in
2 dnl
3 dnl What it does:
4 dnl =============
5 dnl
6 dnl - Determine which version of curses is installed on your system
7 dnl and set the -I/-L/-l compiler entries and add a few preprocessor
8 dnl symbols
9 dnl - Do an AC_SUBST on the CURSES_INCLUDEDIR and CURSES_LIBS so that
10 dnl @CURSES_INCLUDEDIR@ and @CURSES_LIBS@ will be available in
11 dnl Makefile.in's
12 dnl - Modify the following configure variables (these are the only
13 dnl curses.m4 variables you can access from within configure.in)
14 dnl CURSES_INCLUDEDIR - contains -I's and possibly -DRENAMED_CURSES if
15 dnl an ncurses.h that's been renamed to curses.h
16 dnl is found.
17 dnl CURSES_LIBS - sets -L and -l's appropriately
18 dnl CFLAGS - if --with-sco, add -D_SVID3
19 dnl has_curses - exports result of tests to rest of configure
20 dnl
21 dnl Usage:
22 dnl ======
23 dnl 1) Add lines indicated below to acconfig.h
24 dnl 2) call AC_CHECK_CURSES after AC_PROG_CC in your configure.in
25 dnl 3) Instead of #include <curses.h> you should use the following to
26 dnl properly locate ncurses or curses header file
27 dnl
28 dnl #if defined(USE_NCURSES) && !defined(RENAMED_NCURSES)
29 dnl #include <ncurses.h>
30 dnl #else
31 dnl #include <curses.h>
32 dnl #endif
33 dnl
34 dnl 4) Make sure to add @CURSES_INCLUDEDIR@ to your preprocessor flags
35 dnl 5) Make sure to add @CURSES_LIBS@ to your linker flags or LIBS
36 dnl
37 dnl Notes with automake:
38 dnl - call AM_CONDITIONAL(HAS_CURSES, test "$has_curses" = true) from
39 dnl configure.in
40 dnl - your Makefile.am can look something like this
41 dnl -----------------------------------------------
42 dnl INCLUDES= blah blah blah $(CURSES_INCLUDEDIR)
43 dnl if HAS_CURSES
44 dnl CURSES_TARGETS=name_of_curses_prog
45 dnl endif
46 dnl bin_PROGRAMS = other_programs $(CURSES_TARGETS)
47 dnl other_programs_SOURCES = blah blah blah
48 dnl name_of_curses_prog_SOURCES = blah blah blah
49 dnl other_programs_LDADD = blah
50 dnl name_of_curses_prog_LDADD = blah $(CURSES_LIBS)
51 dnl -----------------------------------------------
52 dnl
53 dnl
54 dnl The following lines should be added to acconfig.h:
