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

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

		76
		77
		78	EV can use various backends with various portability issues. The select
		79	backend is the most portable and makes for a good fallback, but it can be
		80	limited to a low number of file descriptors and/or might not compile. If
		81	you have problems with compiling ev_select.c, you might try to play around
		82	with disabling it here, or forcing it to use the fd_set provided by your
		83	OS, via the next question. I highly recommend keeping it in.
		84
		85	EOF
		86
		87	if (prompt ("Enable select backend (y/n)?", "y") =~ /[yY]/) {
		88	$DEFINE .= " -DEV_USE_SELECT=1";

		90	print <<EOF;
		91
		92	* * * * * * * * * * * * * * * * * *
		93
		94
		95	The select backend can operate in two modes. One uses the system-provided
		96	fd_set and is usually limited to 1024 file descriptors (64 on windows),
		97	the other requires your header files to define NFDBITS and declare a
		98	suitable fd_mask type. If you run into problems compiling ev_select.c, you
		99	can try forcing the use of the system fd_set here.
		100
		101	EOF
		102
		103	if (prompt ("Force use of system fd_set for select backend (y/n)?", "n") =~ /[yY]/) {
		104	$DEFINE .= " -DEV_SELECT_USE_FD_SET";
		105	}
		106	} else {
		107	$DEFINE .= " -DEV_USE_SELECT=0";

		111
		112	* * * * * * * * * * * * * * * * * *
		113
		114
		115	The second very portable backend is poll(2). It does not exist on windows
		116	and various versions of Mac OS X (and on the other versions it simply
		117	doesn't work), but works basically everywhere else. It is recommended to use
		118	the default here unless you run into compile problems in ev_poll.c.
		119
		120	EOF
		121
		122	$DEFINE .= " -DEV_USE_POLL=" . (0 + (prompt ("Enable poll backend (y/n)?", (have_inc "poll.h") ? "y" : "n") =~ /[yY]/));

		127
		128
		129	Select and poll make it hard to write efficient servers, especially if the
		130	number of active connections is much lower than the watched ones. GNU/Linux
		131	systems have a more scalable method called "epoll", which EV can use. For
		132	this to work, both your kernel and glibc have to support epoll, but if you
		133	can compile it, the detection will be done at runtime, and EV will safely
		134	fall back to using select when epoll isn't available. If unsure, accept
		135	the default.
		136
		137	EOF
		138
		139	my $can_epoll = have_inc "sys/epoll.h";
		140	$can_epoll = $ENV{EV_EPOLL} if exists $ENV{EV_EPOLL};
		141	$DEFINE .= " -DEV_USE_EPOLL=" . (0 + (prompt ("Enable epoll backend (y/n)?", $can_epoll ? "y" : "n") =~ /[yY]/));

		144
		145	* * * * * * * * * * * * * * * * * *
		146
		147
		148	Similarly to the epoll backend above, EV can take advantage of kqueue on
		149	many BSD systems. Support for kqueue will be detected at runtime, with a
		150	safe fallback to other methods when it cannot be used.
		151
		152	Note that kqueue is broken on most operating systems, so by default it
		153	won't be used on many platforms, but you can still create your own event
		154	loop with kqueue backend if you ask specifically for it.
		155
		156	Here is what we know:
		157
		158	NetBSD: partially working in at least 3.1 and later. Yeah! :)
		159	FreeBSD: broken on at least 6.2-STABLE, spotty in later versions,
		160	sockets likely work, ptys definitely don't.
		161	OpenBSD: reports indicate that it likely doesn't work
		162	(similar problems as on FreeBSD).
		163	OS X: completely, utterly broken on at least <= 10.6.
		164
		165	EOF
		166
		167	my $can_kqueue = have_inc "sys/event.h";
		168	$can_kqueue = $ENV{EV_KQUEUE} if exists $ENV{EV_KQUEUE};
		169	$DEFINE .= " -DEV_USE_KQUEUE=" . (0 + (prompt ("Enable kqueue backend (y/n)?", $can_kqueue ? "y" : "n") =~ /[yY]/));

		172
		173	* * * * * * * * * * * * * * * * * *
		174
		175
		176	Similarly to the kqueue backend above, EV can take advantage of the
		177	solaris 10 event port interface. Support for event ports will be detected
		178	at runtime, with a safe fallback to other methods when it cannot be used.
		179
		180	EOF
		181
		182	$DEFINE .= " -DEV_USE_PORT=" . (0 + (prompt ("Enable event port backend (y/n)?", (have_inc "sys/port.h") ? "y" : "n") =~ /[yY]/));

		185
		186	* * * * * * * * * * * * * * * * * *
		187
		188
		189	EV needs the functions pthread_atfork and clock_gettime. On most systems
		190	you need some special libraries for this (such as -lrt and -lpthread). You
		191	can specify additional libraries to provide these calls (and any other
		192	required by EV) now, or accept the default.
		193
		194	On GNU/Linux systems, EV uses the LSB 3.1 __register_atfork function
		195	to avoid the dependency on libpthread, and directly uses the clock_gettime
		196	syscall to avoid a dependency on librt.
		197
		198	EOF

		208	* * * * * * * * * * * * * * * * * *
		209
		210
		211	A backend of a different kind is the Linux inotify(7) interface, which can
		212	be used to speed up (and reduce resource consumption) of stat watchers. If
		213	you have the include file and libc support for it, it is usually a good
		214	idea to enable it, as kernel availability is detected at runtime.
		215
		216	EOF
		217
		218	my $can_inotify = have_inc "sys/inotify.h";
		219	$can_inotify = $ENV{EV_INOTIFY} if exists $ENV{EV_INOTIFY};

		224	* * * * * * * * * * * * * * * * * *
		225
		226
		227	Another useful bit of functionality is the Linux eventfd, which is useful
		228	for faster signal handling (don't care) and intra-thread communications
		229	(more relevant). Kernel support for this will be probed at runtime, but
		230	your libc must contain the necessary wrapper. Glibc 2.7 and later should
		231	have this wrapper.
		232
		233	EOF
		234
		235	my $can_eventfd = have_inc "sys/eventfd.h";

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

		260	Very rarely, people want to tweak EV even more, e.g. to exclude
		261	or include certain watcher types or backends. This can be done by adding
		262	extra -D options here, or via the EV_EXTRA_DEFS environment variable.
		263
		264	For example, if you run into compile problems because of missing memory
		265	fences (or you just want extra performance), you can tell EV to not support
		266	smp and threads via -DEV_NO_THREADS.
		267
		268	Normal persons just press enter.
