		38	POSIX optionally offers support for a monotonic clock source. EV
		39	can take advantage of this clock source to detect time jumps
		40	reliably. Unfortunately, some systems are bound to be broken, so you can
		41	disable this here: you can completely disable the detection and use of
		42	the monotonic clock by answering 'n' here. Support for this clock type
		43	will otherwise be autodetected at both compile- and runtime.

		54	POSIX optionally offers support for a (potentially) high-resolution
		55	realtime clock interface. In a good implementation, using it is faster
		56	than the normal method of using gettimeofday. Unfortunately, this option
		57	is also bound to be broken on some systems, so you can disable use and
		58	probing of this feature altogether here. Otherwise support for this clock
		59	type will be autodetected at compiletime.

		70	EV can use various backends with various portability issue. The select
		71	backend is the most portable and makes for a good fallback, but it can be
		72	limited to a low number of file descriptors and/or might not compile. If
		73	you have problems with compiling ev_select.c, you might try to play around
		74	with disabling it here, or forcing it to use the fd_set provided by your
		75	OS, via the next question. I highly recommend keeping it in.
		76
		77	EOF
		78
		79	if (prompt ("Enable select backend (y/n)?", "y") =~ /[yY]/) {
		80	$DEFINE .= " -DEV_USE_SELECT=1";
		81
		82	print <<EOF;
		83
		84	* * * * * * * * * * * * * * * * * *
		85
		86
		87	The select backend can operate in two modes. One uses the system-provided
		88	fd_set and is usually limited to 1024 file descriptors (64 on windows),
		89	the other requires your header files to define NFDBITS and declare a
		90	suitable fd_mask type. If you run into problems compiling ev_select.c, you
		91	can try forcing the use of the system fd_set here.
		92
		93	EOF
		94
		95	if (prompt ("Force use of system fd_set for select backend (y/n)?", "n") =~ /[yY]/) {
		96	$DEFINE .= " -DEV_SELECT_USE_FD_SET";
		97	}
		98	} else {
		99	$DEFINE .= " -DEV_USE_SELECT=0";

		103
		104	* * * * * * * * * * * * * * * * * *
		105
		106
		107	The second very portable backend is poll(2). It does not exist on windows
		108	and various versions of Mac OS X (and on the other versions it simply
		109	doesn't work), but works basically everywhere else. It is recommended to use
		110	the default here unless you run into compile problems in ev_poll.c.
		111
		112	EOF
		113
		114	$DEFINE .= " -DEV_USE_POLL=" . (0 + (prompt ("Enable poll backend (y/n)?", (-e "/usr/include/poll.h") ? "y" : "n") =~ /[yY]/));

		119
		120
		121	EV by default uses select, which makes it hard to write efficient servers,
		122	especially if the number of active connections is much lower than the open
		123	ones. GNU/Linux systems have a more scalable method called "epoll", which
		124	EV can use. For this to work, both your kernel and glibc have to support
		125	epoll, but if you can compile it, the detection will be done at runtime,
		126	and EV will safely fall back to using select when epoll isn't available.
		127	If unsure, accept the default.
		128
		129	EOF
		130
		131	$DEFINE .= " -DEV_USE_EPOLL=" . (0 + (prompt ("Enable epoll backend (y/n)?", (-e "/usr/include/sys/epoll.h") ? "y" : "n") =~ /[yY]/));

		136
		137
		138	Similarly to the epoll backend above, EV can take advantage of kqueue on
		139	many BSD systems. Support for kqueue will be detected at runtime, with a
		140	safe fallback to other methods when it cannot be used.
		141
		142	Note that kqueue is broken on most operating systems, so it defaults to
		143	'n' on most platforms that claim to support it. Here is what we know:
		144
		145	OS X: completely, utterly broken on at least <= 10.5.
		146	FreeBSD: broken on at least <= 6.2-STABLE,
		147	sockets and pipes might work, ptys definitely don't.
		148	NetBSD: reports indicate that it likely WORKS. Yeah! :)
		149	OpenBSD: reports indicate that it likely doesn't work
		150	(similar problems as on FreeBSD).

		161
		162
		163	Similarly to the kqueue backend above, EV can take advantage of the
		164	solaris 10 port interface. Support for port will be detected at runtime,
		165	with a safe fallback to other methods when it cannot be used.
		166
		167	EOF

		176	EV needs the functions pthread_atfork and clock_gettime. On most systems
		177	you need some special libraries for this (such as -lrt and -lpthread). You
		178	can specify additional libraries to provide these calls (and any other
		179	required by EV) now, or accept the default.
