		39	POSIX optionally offers support for a monotonic clock source. EV
		40	can take advantage of this clock source to detect time jumps
		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).

		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, so you can disable use and
		60	probing of this feature altogether here. Otherwise support for this clock
		61	type will be autodetected at compiletime.

		72	EV can use various backends with various portability issue. The select
		73	backend is the most portable and makes for a good fallback, but it can be
		74	limited to a low number of file descriptors and/or might not compile. If
		75	you have problems with compiling ev_select.c, you might try to play around
		76	with disabling it here, or forcing it to use the fd_set provided by your
		77	OS, via the next question. I highly recommend keeping it in.
		78
		79	EOF
		80
		81	if (prompt ("Enable select backend (y/n)?", "y") =~ /[yY]/) {
		82	$DEFINE .= " -DEV_USE_SELECT=1";
		83
		84	print <<EOF;
		85
		86	* * * * * * * * * * * * * * * * * *
		87
		88
		89	The select backend can operate in two modes. One uses the system-provided
		90	fd_set and is usually limited to 1024 file descriptors (64 on windows),
		91	the other requires your header files to define NFDBITS and declare a
		92	suitable fd_mask type. If you run into problems compiling ev_select.c, you
		93	can try forcing the use of the system fd_set here.
		94
		95	EOF
		96
		97	if (prompt ("Force use of system fd_set for select backend (y/n)?", "n") =~ /[yY]/) {
		98	$DEFINE .= " -DEV_SELECT_USE_FD_SET";
		99	}
		100	} else {
		101	$DEFINE .= " -DEV_USE_SELECT=0";
		102	}

		105
		106	* * * * * * * * * * * * * * * * * *
		107
		108
		109	The second very portable backend is poll(2). It does not exist on windows
		110	and various versions of Mac OS X (and on the other versions it simply
		111	doesn't work), but works basically everywhere else. It is recommended to use
		112	the default here unless you run into compile problems in ev_poll.c.
		113
		114	EOF
		115
		116	$DEFINE .= " -DEV_USE_POLL=" . (0 + (prompt ("Enable poll backend (y/n)?", (-e "/usr/include/poll.h") ? "y" : "n") =~ /[yY]/));

		121
		122
		123	Select and poll make it hard to write efficient servers, especially if the
		124	number of active connections is much lower than the watched ones. GNU/Linux
		125	systems have a more scalable method called "epoll", which EV can use. For
		126	this to work, both your kernel and glibc have to support epoll, but if you
		127	can compile it, the detection will be done at runtime, and EV will safely
		128	fall back to using select when epoll isn't available. If unsure, accept
		129	the default.
		130
		131	EOF
		132
		133	my $can_epoll = -e "/usr/include/sys/epoll.h";
		134	$can_epoll = $ENV{EV_EPOLL} if exists $ENV{EV_EPOLL};
		135	$DEFINE .= " -DEV_USE_EPOLL=" . (0 + (prompt ("Enable epoll backend (y/n)?", $can_epoll ? "y" : "n") =~ /[yY]/));

		139	* * * * * * * * * * * * * * * * * *
		140
		141
		142	Similarly to the epoll backend above, EV can take advantage of kqueue on
		143	many BSD systems. Support for kqueue will be detected at runtime, with a
		144	safe fallback to other methods when it cannot be used.
		145
		146	Note that kqueue is broken on most operating systems, so by default it
		147	won't be used on many platforms, but you can still create your own event
		148	loop with kqueue backend.
		149
		150	Here is what we know:
		151
		152	NetBSD: partially working in at least 3.1. Yeah! :)
		153	FreeBSD: broken on at least 6.2-STABLE,
		154	sockets likely work, ptys definitely don't.
		155	OpenBSD: reports indicate that it likely doesn't work
		156	(similar problems as on FreeBSD).
		157	OS X: completely, utterly broken on at least < 10.5.
		158
		159	EOF
		160
		161	my $can_kqueue = -e "/usr/include/sys/event.h";
		162	$can_kqueue = $ENV{EV_KQUEUE} if exists $ENV{EV_KQUEUE};
		163	$DEFINE .= " -DEV_USE_KQUEUE=" . (0 + (prompt ("Enable kqueue backend (y/n)?", $can_kqueue ? "y" : "n") =~ /[yY]/));

		166
		167	* * * * * * * * * * * * * * * * * *
		168
		169
		170	Similarly to the kqueue backend above, EV can take advantage of the
		171	solaris 10 event port interface. Support for event ports will be detected
		172	at runtime, with a safe fallback to other methods when it cannot be used.
		173
		174	EOF
		175
		176	$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
		183	EV needs the functions pthread_atfork and clock_gettime. On most systems
		184	you need some special libraries for this (such as -lrt and -lpthread). You
		185	can specify additional libraries to provide these calls (and any other
		186	required by EV) now, or accept the default.
		187
		188	EOF
		189
		190	my $solaris_libs = $^O =~ /solaris/i ? "-lsocket -lnsl" : "";
		191	my $librt = $^O =~ /linux/i ? "-lpthread" : "-lpthread -lrt";
		192	my $LIBS = prompt "Extra libraries for pthread_atfork and clock_gettime?", "$librt $solaris_libs";

		195	print <<EOF;
		196
		197	* * * * * * * * * * * * * * * * * *
		198
		199
		200	A backend of a different kind is the Linux inotify(7) interface, which can
		201	be used to speed up (and reduce resource consumption) of stat watchers. If
		202	you have it, it is usually a good idea to enable it.
		203
		204	EOF
		205
		206	my $can_inotify = -e "/usr/include/sys/inotify.h";
		207	$can_inotify = $ENV{EV_INOTIFY} if exists $ENV{EV_INOTIFY};
		208	$DEFINE .= " -DEV_USE_INOTIFY=" . (0 + (prompt ("Enable inotify support (y/n)?", $can_inotify ? "y" : "n") =~ /[yY]/));

		211
		212	* * * * * * * * * * * * * * * * * *
		213
		214
		215	Another useful bit of functionality is the Linux eventfd, which is useful
		216	for faster signal handling (don't care) and intra-thread communications
		217	(more relevant). Kernel support for this will be probed at runtime, but
		218	your libc must contain the necessary wrapper. Glibc 2.7 and later should
		219	have this wrapper.
		220
