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

		55
		56	POSIX optionally offers support for a (potentially) high-resolution
		57	realtime clock interface. In a good implementation, using it is faster
		58	than the normal method of using gettimeofday. Unfortunately, this option
		59	is also bound to be broken on some systems, and current EV versions do not
		60	actually call gettimeofday very often, so it defaults to no.

		71	EV can use various backends with various portability issues. The select
		72	backend is the most portable and makes for a good fallback, but it can be
		73	limited to a low number of file descriptors and/or might not compile. If
		74	you have problems with compiling ev_select.c, you might try to play around
		75	with disabling it here, or forcing it to use the fd_set provided by your
		76	OS, via the next question. I highly recommend keeping it in.
		77
		78	EOF
		79
		80	if (prompt ("Enable select backend (y/n)?", "y") =~ /[yY]/) {
		81	$DEFINE .= " -DEV_USE_SELECT=1";

		83	print <<EOF;
		84
		85	* * * * * * * * * * * * * * * * * *
		86
		87
		88	The select backend can operate in two modes. One uses the system-provided
		89	fd_set and is usually limited to 1024 file descriptors (64 on windows),
		90	the other requires your header files to define NFDBITS and declare a
		91	suitable fd_mask type. If you run into problems compiling ev_select.c, you
		92	can try forcing the use of the system fd_set here.
		93
		94	EOF
		95
		96	if (prompt ("Force use of system fd_set for select backend (y/n)?", "n") =~ /[yY]/) {
		97	$DEFINE .= " -DEV_SELECT_USE_FD_SET";
		98	}
		99	} else {
		100	$DEFINE .= " -DEV_USE_SELECT=0";

		105	* * * * * * * * * * * * * * * * * *
		106
		107
		108	The second very portable backend is poll(2). It does not exist on windows
		109	and various versions of Mac OS X (and on the other versions it simply
		110	doesn't work), but works basically everywhere else. It is recommended to use
		111	the default here unless you run into compile problems in ev_poll.c.
		112
		113	EOF
		114
		115	$DEFINE .= " -DEV_USE_POLL=" . (0 + (prompt ("Enable poll backend (y/n)?", (-e "/usr/include/poll.h") ? "y" : "n") =~ /[yY]/));

		120
		121
		122	Select and poll make it hard to write efficient servers, especially if the
		123	number of active connections is much lower than the watched ones. GNU/Linux
		124	systems have a more scalable method called "epoll", which EV can use. For
		125	this to work, both your kernel and glibc have to support epoll, but if you
		126	can compile it, the detection will be done at runtime, and EV will safely
		127	fall back to using select when epoll isn't available. If unsure, accept
		128	the default.
		129
		130	EOF
		131
		132	my $can_epoll = -e "/usr/include/sys/epoll.h";
		133	$can_epoll = $ENV{EV_EPOLL} if exists $ENV{EV_EPOLL};

		138	* * * * * * * * * * * * * * * * * *
		139
		140
		141	Similarly to the epoll backend above, EV can take advantage of kqueue on
		142	many BSD systems. Support for kqueue will be detected at runtime, with a
		143	safe fallback to other methods when it cannot be used.
		144
		145	Note that kqueue is broken on most operating systems, so by default it
		146	won't be used on many platforms, but you can still create your own event
		147	loop with kqueue backend if you ask specifically for it.
		148
		149	Here is what we know:
		150
		151	NetBSD: partially working in at least 3.1 and later. Yeah! :)
		152	FreeBSD: broken on at least 6.2-STABLE, spotty in later versions,
		153	sockets likely work, ptys definitely don't.
		154	OpenBSD: reports indicate that it likely doesn't work
		155	(similar problems as on FreeBSD).
		156	OS X: completely, utterly broken on at least <= 10.6.
		157
		158	EOF

		160	my $can_kqueue = -e "/usr/include/sys/event.h";
		161	$can_kqueue = $ENV{EV_KQUEUE} if exists $ENV{EV_KQUEUE};

		166	* * * * * * * * * * * * * * * * * *
		167
		168
		169	Similarly to the kqueue backend above, EV can take advantage of the
		170	solaris 10 event port interface. Support for event ports will be detected
		171	at runtime, with a safe fallback to other methods when it cannot be used.
		172
		173	EOF
		174
		175	$DEFINE .= " -DEV_USE_PORT=" . (0 + (prompt ("Enable event port backend (y/n)?", (-e "/usr/include/sys/port.h") ? "y" : "n") =~ /[yY]/));

		179	* * * * * * * * * * * * * * * * * *
		180
		181
		182	EV needs the functions pthread_atfork and clock_gettime. On most systems
		183	you need some special libraries for this (such as -lrt and -lpthread). You
		184	can specify additional libraries to provide these calls (and any other
		185	required by EV) now, or accept the default.
		186
		187	On GNU/Linux systems, EV uses the LSB 3.1 __register_atfork function
		188	to avoid the dependency on libpthread, and directly uses the clock_gettime
		189	syscall to avoid a dependency on librt.
		190
		191	EOF

		201	* * * * * * * * * * * * * * * * * *
		202
		203
		204	A backend of a different kind is the Linux inotify(7) interface, which can
		205	be used to speed up (and reduce resource consumption) of stat watchers. If
		206	you have the include file and libc support for it, it is usually a good
		207	idea to enable it, as kernel availability is detected at runtime.
		208
		209	EOF
		210
		211	my $can_inotify = -e "/usr/include/sys/inotify.h";
		212	$can_inotify = $ENV{EV_INOTIFY} if exists $ENV{EV_INOTIFY};

		218
		219
		220	Another useful bit of functionality is the Linux eventfd, which is useful
		221	for faster signal handling (don't care) and intra-thread communications
		222	(more relevant). Kernel support for this will be probed at runtime, but
		223	your libc must contain the necessary wrapper. Glibc 2.7 and later should
		224	have this wrapper.
		225
		226	EOF

		237	Another sometimes useful bit of functionality is the Linux signalfd, which
		238	is useful for faster signal handling (don't care). Kernel support for
		239	this will be probed at runtime, but your libc must contain the necessary
		240	wrapper. Glibc 2.7 and later should have this wrapper.

		252
		253	Very rarely, people want to tweak EV even more, e.g. to exclude
		254	or include certain watcher types or backends. This can be done by adding
		255	extra -D options here, or via the EV_EXTRA_DEFS environment variable.
		256
		257	For example, if you run into compile problems because of missing memory
		258	fences (or you just want extra performance), you can tell EV to not support
		259	smp and threads via -DEV_NO_THREADS.
		260
		261	Normal persons just press enter.
