64 make COPTS=-DHAVE_BROKEN_RTC
65
66HAVE_BROKEN_RTC
67 define this on embedded systems which don't have an RTC
68 which keeps time over reboots. Causes dnsmasq to use uptime
69 for timing, and keep lease lengths rather than expiry times
70 in its leases file. This also make dnsmasq "flash disk friendly".
71 Normally, dnsmasq tries very hard to keep the on-disk leases file
72 up-to-date: rewriting it after every renewal. When HAVE_BROKEN_RTC
73 is in effect, the lease file is only written when a new lease is
74 created, or an old one destroyed. (Because those are the only times
75 it changes.) This vastly reduces the number of file writes, and makes
76 it viable to keep the lease file on a flash filesystem.
77 NOTE: when enabling or disabling this, be sure to delete any old
78 leases file, otherwise dnsmasq may get very confused.
79
80HAVE_TFTP
81 define this to get dnsmasq's built-in TFTP server.
82
83HAVE_DHCP
84 define this to get dnsmasq's DHCPv4 server.
85
86HAVE_DHCP6
87 define this to get dnsmasq's DHCPv6 server. (implies HAVE_DHCP).
88
89HAVE_SCRIPT
90 define this to get the ability to call scripts on lease-change.
91
92HAVE_LUASCRIPT
93 define this to get the ability to call Lua script on lease-change. (implies HAVE_SCRIPT)
94
95HAVE_DBUS
96 define this if you want to link against libdbus, and have dnsmasq
97 support some methods to allow (re)configuration of the upstream DNS
98 servers via DBus.
99
Julian Kornbergercaf4d572018-07-21 21:45:03 +0100100HAVE_UBUS

Josh Soref730c6742017-02-06 16:14:04 +0000110 define this to include code which propagates conntrack marks from
Simon Kelleyc72daea2012-01-05 21:33:27 +0000111 incoming DNS queries to the corresponding upstream queries. This adds
112 a build-dependency on libnetfilter_conntrack, but the resulting binary will
113 still run happily on a kernel without conntrack support.
114
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000115HAVE_IPSET
116 define this to include the ability to selectively add resolved ip addresses
117 to given ipsets.
118
Simon Kelley4820dce2012-12-18 18:30:30 +0000119HAVE_AUTH
120 define this to include the facility to act as an authoritative DNS
121 server for one or more zones.
122
Petr Menšík2024f972020-11-25 17:18:55 +0100123HAVE_NETTLEHASH
124 include just hash function from nettle, but no DNSSEC.
125
Simon Kelley063efb32014-06-17 19:49:31 +0100126HAVE_DNSSEC
127 include DNSSEC validator.

Simon Kelley6b173352018-05-08 18:32:14 +0100129HAVE_DUMPFILE

131
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100132HAVE_LOOP
133 include functionality to probe for and remove DNS forwarding loops.
134

136 use the Linux inotify facility to efficiently re-read configuration files.

Simon Kelleyc72daea2012-01-05 21:33:27 +0000151 with something like "make COPTS=-DNO_SCRIPT" will do the trick.
