## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

.SH NAME
igmpproxy.conf \- Configuration file for
.BR igmpproxy (8)
multicast daemon
.SH DESCRIPTION
.B igmpproxy.conf
contains the configuration for the
.B igmpproxy
multicast daemon. It defines which network interfaces should be
used by the routing daemon. Each interface must be give one of the following roles:
.B upstream
,
.B downstream
or
.B disabled
.
The
.B upstream
network interface is the outgoing interface which is responsible for communicating
to available multicast data sources. There can only be one upstream interface.
.B Downstream
network interfaces are the distribution interfaces to the destination networks,
where multicast clients can join groups and receive multicast data. One or more
downstream interfaces must be configured.
On
.B disabled
network interfaces all IGMP or multicast traffic is ignored altogether. If multiple
IP addresses is used on one single interface (ae. eth0:1 ...), all interface
aliases not in use should be configured as disabled.
Any line in the configuration file starting with
.B #
is treated as a comment. Keywords and parameters can be distributed over many lines.
The configuration file has two main keywords:
.B quickleave
.RS
Enables quickleave mode. In this mode the daemon will send a Leave IGMP message
upstream as soon as it receives a Leave message for any downstream interface.
The daemon will then ask for Membership reports on the downstream interfaces,
and if a report is received the group is joined again upstream. Normally this
is not noticed at all by clients on the downstream networks. If it's vital
that the daemon should act exactly as a real multicast client on the upstream
interface, this function should not be used. Disabling this function increases
the risk of bandwidth saturation.
.RE
.B phyint
.I interface
.I role
[ ratelimit
.I limit
] [ threshold
.I ttl
] [ altnet
.I networkaddr ...
]
.RS
Defines the state and settings of a network interface.
.RE
.SH PHYINT OPTIONS
.B interface
.RS
The name of the interface the settings are for. This option is required for
phyint settings.
.RE
.B role
.RS
The role of the interface. This should be either
.B upstream
(only one interface),
.B downstream
(one or more interfaces) or
.B disabled
\&. This option is required.
.RE
.B ratelimit
.I limit
.RS
Defines a ratelimit for the network interface. If ratelimit is set to 0 (default),
no ratelimit will be applied. This setting is optional.
.RE
.B threshold
.I ttl
.RS
Defines the TTL threshold for the network interface. Packets with a lower TTL than the
threshols value will be ignored. This setting is optional, and by default the threshold is 1.
.RE
.B altnet
.I networkaddr
\&...
.RS
Defines alternate sources for multicasting and IGMP data. The network address must be on the
following format 'a.b.c.d/n'. By default the router will accept data from sources on the same
network as configured on an interface. If the multicast source lies on a remote network, one
must define from where traffic should be accepted.
This is especially useful for the upstream interface, since the source for multicast
traffic is often from a remote location. Any number of altnet parameters can be specified.
.RE
.B whitelist
.I networkaddr
.RS
Defines a whitelist for multicast groups. The network address must be in the following
format 'a.b.c.d/n'. If you want to allow one single group use a network mask of /32,
i.e. 'a.b.c.d/32'.
By default all multicast groups are allowed on any downstream interface. If at least one
whitelist entry is defined, all igmp membership reports for not explicitly whitelisted
multicast groups will be ignored and therefore not be served by igmpproxy. This is especially
useful, if your provider does only allow a predefined set of multicast groups. These whitelists
are only obeyed by igmpproxy itself, they won't prevent any other igmp client running on the
same machine as igmpproxy from requesting 'unallowed' multicast groups.
You may specify as many whitelist entries as needed. Although you should keep it as simple as
possible, as this list is parsed for every membership report and therefore this increases igmp
response times. Often used or large groups should be defined first, as parsing ends as soon as
a group matches an entry.
You may also specify whitelist entries for the upstream interface. Only igmp membership reports
for explicitly whitelisted multicast groups will be sent out on the upstream interface. This
is useful if you want to use multicast groups only between your downstream interfaces, like SSDP
from a UPnP server.

.SH NAME
igmpproxy \- Multicast router utilizing IGMP forwarding
.SH SYNOPSIS
.B igmpproxy [-h] [-n] [-d] [-v [-v]]
.I config-file
.SH DESCRIPTION
.B igmpproxy
is a simple multicast routing daemon which uses IGMP forwarding to
dynamically route multicast traffic. Routing is done by defining an
"upstream" interface on which the daemon act as a normal Multicast
client, and one or more "downstream" interfaces that serves clients
on the destination networks. This is useful in situations where other
dynamic multicast routers (like 'mrouted' or 'pimd') cannot be used.
Since
.B igmpproxy
only uses IGMP signalling, the daemon is only suited for situations
where multicast traffic comes from only one neighbouring network.
In more advanced cases, 'mrouted' or 'pimd' is probably more suited.
The daemon is not designed for cascading, and probably won't scale
very well.
Currently only IGMPv1 and v2 is supported on downstream interfaces.
On the upstream interface the kernel IGMP client implementation is used,
and supported IGMP versions is therefore limited to that supported by the
kernel.
.SH OPTIONS
.IP -h
Display help.
.IP -v
Verbose logging. Set logging level to INFO instead of WARNING used by default.
.IP -vv
More verbose logging. Set logging level to DEBUG.
.IP -n
Do not run as a daemon.
.IP -d
Output log messages to STDERR instead of to
.BR syslog (3).
Implies \fB\-n\fP.
.SH LIMITS
The current version compiles and runs fine with the Linux kernel version 2.4. The known limits are:
.B Multicast routes:
more then 200
.B Multicast group membership:
max. 20
.SH FILES
.TP
.B /proc/net/ip_mr_cache
- contains the active multicast routes
.TP
.B /proc/net/ip_mr_vif
- contains the 'virtual' interfaces used by the active multicast routing daemon
.TP
.B /proc/sys/net/ipv4/conf//force_igmp_version
- can be set to control what IGMP version the kernel should use on the upstream interface.
Ex.: 'echo 2 > /proc/sys/net/ipv4/conf/eth0/force_igmp_version' will force the kernel to
use IGMPv2 on eth0 (provided this is the upstream interface).

.SH BUGS
Currently none (but there probably will be :-/ )

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

Basic Installation
==================
Briefly, the shell command './configure && make && make install'
should configure, build, and install this package. The following
more-detailed instructions are generic; see the 'README' file for
instructions specific to this package. Some packages provide this
'INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
The 'configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a 'Makefile' in each directory of the package.
It may also create one or more '.h' files containing system-dependent
definitions. Finally, it creates a shell script 'config.status' that
you can run in the future to recreate the current configuration, and a
file 'config.log' containing compiler output (useful mainly for
debugging 'configure').
It can also use an optional file (typically called 'config.cache' and
enabled with '--cache-file=config.cache' or simply '-C') that saves the
results of its tests to speed up reconfiguring. Caching is disabled by
default to prevent problems with accidental use of stale cache files.
If you need to do unusual things to compile the package, please try
to figure out how 'configure' could check whether to do them, and mail
diffs or instructions to the address given in the 'README' so they can
be considered for the next release. If you are using the cache, and at
some point 'config.cache' contains results you don't want to keep, you
may remove or edit it.
The file 'configure.ac' (or 'configure.in') is used to create
'configure' by a program called 'autoconf'. You need 'configure.ac' if
you want to change it or regenerate 'configure' using a newer version of
'autoconf'.
The simplest way to compile this package is:
1. 'cd' to the directory containing the package's source code and type
'./configure' to configure the package for your system.
Running 'configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type 'make' to compile the package.
3. Optionally, type 'make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type 'make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the 'make install' phase executed with root
privileges.
5. Optionally, type 'make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior 'make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing 'make clean'. To also remove the
files that 'configure' created (so you can compile the package for
a different kind of computer), type 'make distclean'. There is
also a 'make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type 'make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide 'make
distcheck', which can by used by developers to test that all other
targets like 'make install' and 'make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the 'configure' script does not know about. Run './configure --help'
for details on some of the pertinent environment variables.
You can give 'configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here is
an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU 'make'. 'cd' to the
directory where you want the object files and executables to go and run
the 'configure' script. 'configure' automatically checks for the source
code in the directory that 'configure' is in and in '..'. This is known
as a "VPATH" build.
With a non-GNU 'make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use 'make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple '-arch' options to the
compiler but only a single '-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the 'lipo' tool if you have problems.
Installation Names
==================
By default, 'make install' installs the package's commands under
'/usr/local/bin', include files under '/usr/local/include', etc. You
can specify an installation prefix other than '/usr/local' by giving
'configure' the option '--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like '--bindir=DIR' to specify different values for particular
kinds of files. Run 'configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the default
for these options is expressed in terms of '${prefix}', so that
specifying just '--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to 'configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
'make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, 'make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
'${prefix}'. Any directories that were specified during 'configure',
but not in terms of '${prefix}', must each be overridden at install time
for the entire installation to be relocated. The approach of makefile
variable overrides for each directory variable is required by the GNU
Coding Standards, and ideally causes no recompilation. However, some
platforms have known limitations with the semantics of shared libraries
that end up requiring recompilation when using this method, particularly
noticeable in packages that use GNU Libtool.
The second method involves providing the 'DESTDIR' variable. For
example, 'make install DESTDIR=/alternate/directory' will prepend
'/alternate/directory' before all installation names. The approach of
'DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of '${prefix}'
at 'configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving 'configure' the
option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
Some packages pay attention to '--enable-FEATURE' options to
'configure', where FEATURE indicates an optional part of the package.
They may also pay attention to '--with-PACKAGE' options, where PACKAGE
is something like 'gnu-as' or 'x' (for the X Window System). The
'README' should mention any '--enable-' and '--with-' options that the
package recognizes.
For packages that use the X Window System, 'configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the 'configure' options '--x-includes=DIR' and
'--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of 'make' will be. For these packages, running './configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with 'make V=1'; while running './configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with 'make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC
is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
HP-UX 'make' updates targets which have the same time stamps as their
prerequisites, which makes it generally unusable when shipped generated
files such as 'configure' are involved. Use GNU 'make' instead.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its '' header file. The option '-nodtk' can be used as a
workaround. If GNU CC is not installed, it is therefore recommended to
try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put '/usr/ucb' early in your 'PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in '/usr/bin'. So, if you need '/usr/ucb'
in your 'PATH', put it _after_ '/usr/bin'.
On Haiku, software installed for all users goes in '/boot/common',
not '/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features 'configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, 'configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
'--build=TYPE' option. TYPE can either be a short name for the system
type, such as 'sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file 'config.sub' for the possible values of each field. If
'config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option '--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with '--host=TYPE'.
Sharing Defaults
================
If you want to set default values for 'configure' scripts to share,
you can create a site shell script called 'config.site' that gives
default values for variables like 'CC', 'cache_file', and 'prefix'.
'configure' looks for 'PREFIX/share/config.site' if it exists, then
'PREFIX/etc/config.site' if it exists. Or, you can set the
'CONFIG_SITE' environment variable to the location of the site script.
A warning: not all 'configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to 'configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the 'configure' command line, using 'VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified 'gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
Autoconf limitation. Until the limitation is lifted, you can use this
workaround:
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
'configure' Invocation
======================
'configure' recognizes the following options to control how it
operates.
'--help'
'-h'
Print a summary of all of the options to 'configure', and exit.
'--help=short'
'--help=recursive'
Print a summary of the options unique to this package's
'configure', and exit. The 'short' variant lists options used only
in the top level, while the 'recursive' variant lists options also
present in any nested packages.
'--version'
'-V'
Print the version of Autoconf used to generate the 'configure'
script, and exit.
'--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally 'config.cache'. FILE defaults to '/dev/null' to
disable caching.
'--config-cache'
'-C'
Alias for '--cache-file=config.cache'.
'--quiet'
'--silent'
'-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to '/dev/null' (any error
messages will still be shown).
'--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
'configure' can determine that directory automatically.
'--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names:: for
more details, including other options available for fine-tuning the
installation locations.
'--no-create'
'-n'
Run the configure checks, but stop before creating any output
files.
'configure' also accepts some other, not widely useful, options. Run
'configure --help' for more details.

* Free BSD Compilation Patch
On FreeBSD compilation failed due to missing includes in os-freebsd.h.
This was causing errors about undefined structs and types in missing includes.
Also defines __BSD_VISIBLE due to FreeBSD not providing u_int, u_long etc

* Improve downstream host tracking for quickleave mode
Use bit based per multicast route hash table for tracking downstream hosts.
For hasing function is used 32bit MurmurHash3 with pseudorandom seed and
size of hash table can be configured via a new "hashtablesize" token in
config file. Default size of hash table is 32 bytes, so it can store
approximatelly 128 hosts which is half of /24 subnet. For home networks
this should be sane default value.

* Fix running as daemon
Commit 29eab814175d7754797c51ed6d4d1d7c91155cca introduced a new flag,
-n, which allows making igmpproxy not run as a daemon (fork and run in
the foreground). However, the boolean flag controlling this option was
always true, thus causing igmpproxy to never run as a daemon,
regardless whether the switch was specified or not.

* Fix compilation on FreeBSD systems
FreeBSD's struct ifreq does not have member ifr_netmask. Instead for
SIOCGIFNETMASK ioctl FreeBSD kernel fills ifru_addr member. As both members
ifr_netmask and ifru_addr are stored in same union on Linux, they alias to
same data and therefore this change does not break Linux support.

* igmp: Fix incorrect index calculation of upstream VIF
igmpproxy uses a number of different kinds of indices to identify
interfaces:
- The system interface index, as used by IfDescVc / getIfByIx. These
identify and enumerate all interfaces on the system.
- The Virtual Interface Index (VIF). These identify only those
interfaces which take part in multicast routing.
- The upstream interface index, as used in upStreamVif, which
identifies/enumerates only those interfaces that are configured as
multicast upstream interfaces in igmpproxy's configuration.
activateRoute's expected a VIF index for its upstrVif parameter,
however it was being passed upStreamVif[i]-1 (i.e. the system
interface index of the upstream interface, minus one, where i is the
current upstream interface index being iterated).
It is unclear what the logic was behind the upStreamVif[i]-1
expression, as it existed ever since the upstrVif parameter was
introduced in b55e0125c79fc9dbc95c6d6ab1121570f0c6f80f. igmpproxy
working as expected highly depended on the system configuration and
enumeration order of network interfaces.

* Apply 3-clause BSD license on the mrouted source code
mrouted was originally licensed under the proprietary Stanford license.
Later, in March 2003 OpenBSD team managed to convince Stanford to release
mrouted under a free BSD-3-clause license. See details at:
http://www.openbsd.org/cgi-bin/cvsweb/src/usr.sbin/mrouted/LICENSE
http://troglobit.com/mrouted.html
igmpproxy is licensed under the proprietary Stanford and GPL-2+ license,
but all authors and contributors of igmpproxy agreed that their changes and
contributions can be licensed under GPL-2+ license.
So now igmpproxy software can be redistributed under BSD-3-clause and
GPL-2+. And so is finally GPL-2+ compatible.
Below are agreement sent by all igmpproxy contributors:

* Support multiple multicast sources
If a multicast packet comes in on the upstream interface to a group
address, but from a different IP source than previously seen, igmpproxy
will forget about the old source, and the corresponding multicast route
will time out shortly - even if the multicast stream from the original
source is never interrupted.
I haven't investigated what in particular the suspicious packet is; it did
however originate from the multicast router.
The submitted patch resolves the issue by adding support for multiple
source IPs for any given group. Instead of keeping a single source address,
MAX_ORIGINS addresses are kept. If we run out of source address slots, the
least recently used one will be reused.

* downstream link change detect on the fly
This patch can work on a PPP server. When PPP client link up, the new link
will set as downstrem interface automatically.
New feature:
1. Multiple upstream interface
2. Set default Vif State in config file
3. Swith auto scan function on/off in config file.
When config file have set "defaultdown" means VIFs default status is
downstream, oterwise will be disable.
When config file have set "rescanvif" the igmpproxy will scan the interface
state and auto add new Vif, it is very helpful in ppp links.

* Improved the handling of groups that are used on more than one interface.
This patch has two effects. First, the quickleave feature/behaviour is disabled for all groups that are used on more than one interface. The idea of quickleave is to leave a group fast and later figure out whether there is still somebody interested in that group. For groups used on more than one interface, it is already known that there is still somebody interested in that group.
Second, when a leave is received for a group that is used on more than one interface, igmpproxy sends queries on all interface to discover remeining listeners for that group. Previously these queries were only send on the interface the leave was received on, so that listeners on the other interfaces were not discovered and the group might be left on the upstream router incorrectly.
This patch can be improved by sending the queries only on the interface the leave was received on and adapting the algorithm in internAgeRoute(...) in rttable.c in a way that only one interface is actually processed and all other interfaces of the route are silently assumed to be still active.

* Restrict igmp reports for downstream interfaces (wrt #2833339)
atm all igmp membership reports are forwarded to the upstream interface.
Unfortunately some ISP Providers restrict some multicast groups (esp. those
that are defined as local link groups and that are not supposed to be
forwarded to the wan, i.e 224.0.0.0/24). Therefore there should be some
kind of black oder whitelisting.

* Improve getIfByAddress() function (wrt #2835052)
getIfByAddress does not find the best iterface in case of overlaping
networks. This patchs scans through all interfaces (and networks) and picks
the one with the longest subnet.

* Fix nextConfigToken() function (wrt #2838154)
The nextConfigToken() returns NULL when EOF reached even if token
was read already. This results in loss of last token in file usually.
Let it return unterminated token if it is non-empty already.

* Avoid inclusion if linux/in.h (wrt #2787118)
The linux/in.h header conflicts with the netinet/in.h header in
certain Linux distributions. So let's ensure that linux/in.h will
never be included neither directly nor from linux/mroute.h.
