+# Use of these switches will guarantee that the .so files are created in the

+# Note that the shared libraries with callouts should not be used together with
+# the --enable-static-link option. With this option, the bind10 libraries are
+# statically linked with the program and if the callout invokes the methods
+# which belong to these libraries, the library with the callout will get its
+# own copy of the static objects (e.g. logger, ServerHooks) and that will lead
+# to unexpected errors. For this reason, the --enable-static-link option is

+/// @brief DHCPv6 client used for unit testing.
+///
+/// This class implements a DHCPv6 "client" which interoperates with the
+/// @c NakedDhcpv6Srv class. It calls @c NakedDhcpv6Srv::fakeReceive to
+/// deliver client messages to the server for processing. The server places
+/// the response in the @c NakedDhcpv6Srv::fake_sent_ container. The client
+/// pops messages from this container which simulates reception of the
+/// response from the server.
+///
+/// The client maintains the leases it acquired from the server. If it has
+/// acquired the lease as a result of SARR exchange, it will use this lease
+/// when the Rebind process is triggered by the unit test.
+///
+/// The client exposes a set of functions which simulate different exchange
+/// types between the client and the server. It also provides the access to
+/// the objects encapsulating responses from the server so as it is possible
+/// to verify from the unit test that the server's response is correct.
+///
+/// @todo This class has been implemented to simplify the structure of the
+/// unit test and to make unit tests code self-explanatory. Currently,
+/// this class is mostly used by the unit tests which test Rebind processing
+/// logic. At some point we may want to use this class to test some other
+/// message types, e.g. Renew, in which case it may need to be extended.
+/// Also, once we implement the support for multiple IAAddr and IAPrefix
+/// options within single IA, the logic which maintains leases will have
+/// to be extended to support it.

+/// - Configuration 0:
+/// Single subnet with two reservations, one with a hostname, one without
+///
+/// - Configuration 1:
+/// Multiple reservations using different host identifiers.
+///
+/// - Configuration 2:
+/// Same as configuration 1 but 'host-reservation-identifiers' specified
+/// in non-default order.
+///
+/// - Configuration 3:
+/// - Used to test that host specific options override pool specific,
+/// subnet specific and global options.
+///
+/// - Configuration 4:
+/// - Used to test that client receives options solely specified in a
+/// host scope.
+///
+/// - Configuration 5:
+/// - Used to test that host specific vendor options override globally
+/// specified vendor options.
+///
+/// - Configuration 6:
+/// - One subnet with very short pool, i.e. two addresses
+///
+/// - Configuration 7:
+/// - Similar to Configuration 6, but one of the addresses reserved to client
+/// with the DUID 04:03:02:01.
+///
+/// Descriptions of next configurations are in the comment with the number.

+/// @brief Set of JSON configurations used by the SARR unit tests.
+///
+/// - Configuration 0:
+/// - one subnet 3000::/32 used on eth0 interface
+/// - prefixes of length 64, delegated from the pool: 2001:db8:3::/48
+/// - the delegated prefix was intentionally selected to not match the
+/// subnet prefix, to test that the delegated prefix doesn't need to
+/// match the subnet prefix
+///
+/// - Configuration 1:
+/// - two subnets 2001:db8:1::/48 and 2001:db8:2::/48
+/// - first subnet assigned to interface eth0, another one assigned to eth1
+/// - one pool for subnet in a range of 2001:db8:X::1 - 2001:db8:X::10,
+/// where X is 1 or 2
+/// - enables Rapid Commit for the first subnet and disables for the second
+/// one
+/// - DNS updates enabled
+///
+/// - Configuration 2:
+/// - single subnet 3000::/32,
+/// - two options specified in the subnet scope,
+/// - one option specified at the global scope,
+/// - two address pools: 3000::10-3000::20, 3000::40-3000::50,
+/// - two prefix pools: 2001:db8:3::/64 and 2001:db8:4::/64,
+/// - an option with unique value specified for each pool, so as it is
+/// possible to test that pool specific options can be assigned.
+///
+/// - Configuration 3:
+/// - one subnet 3000::/32 used on eth0 interface
+/// - prefixes of length 64, delegated from the pool: 2001:db8:3::/48
+/// - Excluded Prefix specified (RFC 6603).
+///
+/// - Configuration 4:
+/// - Simple configuration with a single subnet
+/// - Two host reservations, one out of the pool, another one in pool
+/// - The reservations-in-subnet and reservations-out-of-pool flags are set to
+/// true to test that only out of pool reservations are honored.
+///
+/// - Configuration 5:
+/// - Selects random allocator for addresses.
+/// - One subnet with three distinct pools.
+/// - Random allocator enabled globally for addresses.
+/// - Iterative allocator for prefix delegation.
+///
+/// - Configuration 6:
+/// - Selects random allocator for delegated prefixes.
+/// - One subnet with three distinct pools.
+/// - Random allocator enabled globally for delegated prefixes.
+/// - Iterative allocator for address allocation.
