0	11	Basic Installation
1	12	==================
2	13
3		These are generic installation instructions.
	14	Briefly, the shell command `./configure && make && make install'
	15	should configure, build, and install this package. The following
	16	more-detailed instructions are generic; see the `README' file for
	17	instructions specific to this package. Some packages provide this
	18	`INSTALL' file but do not implement all of the features documented
	19	below. The lack of an optional feature in a given package is not
	20	necessarily a bug. More recommendations for GNU packages can be found
	21	in *note Makefile Conventions: (standards)Makefile Conventions.
4	22
5	23	The `configure' shell script attempts to guess correct values for
6	24	various system-dependent variables used during compilation. It uses
7	25	those values to create a `Makefile' in each directory of the package.
8	26	It may also create one or more `.h' files containing system-dependent
9	27	definitions. Finally, it creates a shell script `config.status' that
10		you can run in the future to recreate the current configuration, a file
11		`config.cache' that saves the results of its tests to speed up
12		reconfiguring, and a file `config.log' containing compiler output
13		(useful mainly for debugging `configure').
	28	you can run in the future to recreate the current configuration, and a
	29	file `config.log' containing compiler output (useful mainly for
	30	debugging `configure').
	31
	32	It can also use an optional file (typically called `config.cache'
	33	and enabled with `--cache-file=config.cache' or simply `-C') that saves
	34	the results of its tests to speed up reconfiguring. Caching is
	35	disabled by default to prevent problems with accidental use of stale
	36	cache files.
14	37
15	38	If you need to do unusual things to compile the package, please try
16	39	to figure out how `configure' could check whether to do them, and mail
17	40	diffs or instructions to the address given in the `README' so they can
18		be considered for the next release. If at some point `config.cache'
19		contains results you don't want to keep, you may remove or edit it.
20
21		The file `configure.in' is used to create `configure' by a program
22		called `autoconf'. You only need `configure.in' if you want to change
23		it or regenerate `configure' using a newer version of `autoconf'.
24
25		The simplest way to compile this package is:
	41	be considered for the next release. If you are using the cache, and at
	42	some point `config.cache' contains results you don't want to keep, you
	43	may remove or edit it.
	44
	45	The file `configure.ac' (or `configure.in') is used to create
	46	`configure' by a program called `autoconf'. You need `configure.ac' if
	47	you want to change it or regenerate `configure' using a newer version
	48	of `autoconf'.
	49
	50	The simplest way to compile this package is:
26	51
27	52	1. `cd' to the directory containing the package's source code and type
28		`./configure' to configure the package for your system. If you're
29		using `csh' on an old version of System V, you might need to type
30		`sh ./configure' instead to prevent `csh' from trying to execute
31		`configure' itself.
32
33		Running `configure' takes awhile. While running, it prints some
34		messages telling which features it is checking for.
	53	`./configure' to configure the package for your system.
	54
	55	Running `configure' might take a while. While running, it prints
	56	some messages telling which features it is checking for.
35	57
36	58	2. Type `make' to compile the package.
37	59
38	60	3. Optionally, type `make check' to run any self-tests that come with
39		the package.
	61	the package, generally using the just-built uninstalled binaries.
40	62
41	63	4. Type `make install' to install the programs and any data files and
42		documentation.
43
44		5. You can remove the program binaries and object files from the
	64	documentation. When installing into a prefix owned by root, it is
	65	recommended that the package be configured and built as a regular
	66	user, and only the `make install' phase executed with root
	67	privileges.
	68
	69	5. Optionally, type `make installcheck' to repeat any self-tests, but
	70	this time using the binaries in their final installed location.
	71	This target does not install anything. Running this target as a
	72	regular user, particularly if the prior `make install' required
	73	root privileges, verifies that the installation completed
	74	correctly.
	75
	76	6. You can remove the program binaries and object files from the
45	77	source code directory by typing `make clean'. To also remove the
46	78	files that `configure' created (so you can compile the package for
47	79	a different kind of computer), type `make distclean'. There is

50	82	all sorts of other programs in order to regenerate files that came
51	83	with the distribution.
52	84
	85	7. Often, you can also type `make uninstall' to remove the installed
	86	files again. In practice, not all packages have tested that
	87	uninstallation works correctly, even though it is required by the
	88	GNU Coding Standards.
	89
	90	8. Some packages, particularly those that use Automake, provide `make
	91	distcheck', which can by used by developers to test that all other
	92	targets like `make install' and `make uninstall' work correctly.
	93	This target is generally not run by end users.
	94
53	95	Compilers and Options
54	96	=====================
55	97
56	98	Some systems require unusual options for compilation or linking that
57		the `configure' script does not know about. You can give `configure'
58		initial values for variables by setting them in the environment. Using
59		a Bourne-compatible shell, you can do that on the command line like
60		this:
61		CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
62
63		Or on systems that have the `env' program, you can do it like this:
64		env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
	99	the `configure' script does not know about. Run `./configure --help'
	100	for details on some of the pertinent environment variables.
	101
	102	You can give `configure' initial values for configuration parameters
	103	by setting variables in the command line or in the environment. Here
	104	is an example:
	105
	106	./configure CC=c99 CFLAGS=-g LIBS=-lposix
	107
	108	*Note Defining Variables::, for more details.
65	109
66	110	Compiling For Multiple Architectures
67	111	====================================
68	112
69	113	You can compile the package for more than one kind of computer at the
70	114	same time, by placing the object files for each architecture in their
71		own directory. To do this, you must use a version of `make' that
72		supports the `VPATH' variable, such as GNU `make'. `cd' to the
	115	own directory. To do this, you can use GNU `make'. `cd' to the
73	116	directory where you want the object files and executables to go and run
74	117	the `configure' script. `configure' automatically checks for the
75		source code in the directory that `configure' is in and in `..'.
76
77		If you have to use a `make' that does not supports the `VPATH'
78		variable, you have to compile the package for one architecture at a time
79		in the source code directory. After you have installed the package for
80		one architecture, use `make distclean' before reconfiguring for another
81		architecture.
	118	source code in the directory that `configure' is in and in `..'. This
	119	is known as a "VPATH" build.
	120
	121	With a non-GNU `make', it is safer to compile the package for one
	122	architecture at a time in the source code directory. After you have
	123	installed the package for one architecture, use `make distclean' before
	124	reconfiguring for another architecture.
	125
	126	On MacOS X 10.5 and later systems, you can create libraries and
	127	executables that work on multiple system types--known as "fat" or
	128	"universal" binaries--by specifying multiple `-arch' options to the
	129	compiler but only a single `-arch' option to the preprocessor. Like
	130	this:
	131
	132	./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
	133	CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
	134	CPP="gcc -E" CXXCPP="g++ -E"
	135
	136	This is not guaranteed to produce working output in all cases, you
	137	may have to build one architecture at a time and combine the results
	138	using the `lipo' tool if you have problems.
82	139
83	140	Installation Names
84	141	==================
85	142
86		By default, `make install' will install the package's files in
87		`/usr/local/bin', `/usr/local/man', etc. You can specify an
88		installation prefix other than `/usr/local' by giving `configure' the
89		option `--prefix=PATH'.
	143	By default, `make install' installs the package's commands under
	144	`/usr/local/bin', include files under `/usr/local/include', etc. You
	145	can specify an installation prefix other than `/usr/local' by giving
	146	`configure' the option `--prefix=PREFIX', where PREFIX must be an
	147	absolute file name.
90	148
91	149	You can specify separate installation prefixes for
92	150	architecture-specific files and architecture-independent files. If you
93		give `configure' the option `--exec-prefix=PATH', the package will use
94		PATH as the prefix for installing programs and libraries.
95		Documentation and other data files will still use the regular prefix.
	151	pass the option `--exec-prefix=PREFIX' to `configure', the package uses
	152	PREFIX as the prefix for installing programs and libraries.
	153	Documentation and other data files still use the regular prefix.
96	154
97	155	In addition, if you use an unusual directory layout you can give
98		options like `--bindir=PATH' to specify different values for particular
	156	options like `--bindir=DIR' to specify different values for particular
99	157	kinds of files. Run `configure --help' for a list of the directories
100		you can set and what kinds of files go in them.
	158	you can set and what kinds of files go in them. In general, the
	159	default for these options is expressed in terms of `${prefix}', so that
	160	specifying just `--prefix' will affect all of the other directory
	161	specifications that were not explicitly provided.
	162
	163	The most portable way to affect installation locations is to pass the
	164	correct locations to `configure'; however, many packages provide one or
	165	both of the following shortcuts of passing variable assignments to the
	166	`make install' command line to change installation locations without
	167	having to reconfigure or recompile.
	168
	169	The first method involves providing an override variable for each
	170	affected directory. For example, `make install
	171	prefix=/alternate/directory' will choose an alternate location for all
	172	directory configuration variables that were expressed in terms of
	173	`${prefix}'. Any directories that were specified during `configure',
	174	but not in terms of `${prefix}', must each be overridden at install
	175	time for the entire installation to be relocated. The approach of
	176	makefile variable overrides for each directory variable is required by
	177	the GNU Coding Standards, and ideally causes no recompilation.
	178	However, some platforms have known limitations with the semantics of
	179	shared libraries that end up requiring recompilation when using this
	180	method, particularly noticeable in packages that use GNU Libtool.
	181
	182	The second method involves providing the `DESTDIR' variable. For
	183	example, `make install DESTDIR=/alternate/directory' will prepend
	184	`/alternate/directory' before all installation names. The approach of
	185	`DESTDIR' overrides is not required by the GNU Coding Standards, and
	186	does not work on platforms that have drive letters. On the other hand,
	187	it does better at avoiding recompilation issues, and works well even
	188	when some directory options were not specified in terms of `${prefix}'
	189	at `configure' time.
	190
	191	Optional Features
	192	=================
101	193
102	194	If the package supports it, you can cause programs to be installed
103	195	with an extra prefix or suffix on their names by giving `configure' the
104	196	option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
105
106		Optional Features
107		=================
108	197
109	198	Some packages pay attention to `--enable-FEATURE' options to
110	199	`configure', where FEATURE indicates an optional part of the package.

118	207	you can use the `configure' options `--x-includes=DIR' and
119	208	`--x-libraries=DIR' to specify their locations.
120	209
	210	Some packages offer the ability to configure how verbose the
	211	execution of `make' will be. For these packages, running `./configure
	212	--enable-silent-rules' sets the default to minimal output, which can be
	213	overridden with `make V=1'; while running `./configure
	214	--disable-silent-rules' sets the default to verbose, which can be
	215	overridden with `make V=0'.
	216
	217	Particular systems
	218	==================
	219
	220	On HP-UX, the default C compiler is not ANSI C compatible. If GNU
	221	CC is not installed, it is recommended to use the following options in
	222	order to use an ANSI C compiler:
	223
	224	./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
	225
	226	and if that doesn't work, install pre-built binaries of GCC for HP-UX.
	227
	228	HP-UX `make' updates targets which have the same time stamps as
	229	their prerequisites, which makes it generally unusable when shipped
	230	generated files such as `configure' are involved. Use GNU `make'
	231	instead.
	232
	233	On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
	234	parse its `<wchar.h>' header file. The option `-nodtk' can be used as
	235	a workaround. If GNU CC is not installed, it is therefore recommended
	236	to try
	237
	238	./configure CC="cc"
	239
	240	and if that doesn't work, try
	241
	242	./configure CC="cc -nodtk"
	243
	244	On Solaris, don't put `/usr/ucb' early in your `PATH'. This
	245	directory contains several dysfunctional programs; working variants of
	246	these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
	247	in your `PATH', put it _after_ `/usr/bin'.
	248
	249	On Haiku, software installed for all users goes in `/boot/common',
	250	not `/usr/local'. It is recommended to use the following options:
	251
	252	./configure --prefix=/boot/common
	253
121	254	Specifying the System Type
122	255	==========================
123	256
124		There may be some features `configure' can not figure out
125		automatically, but needs to determine by the type of host the package
126		will run on. Usually `configure' can figure that out, but if it prints
127		a message saying it can not guess the host type, give it the
128		`--host=TYPE' option. TYPE can either be a short name for the system
129		type, such as `sun4', or a canonical name with three fields:
	257	There may be some features `configure' cannot figure out
	258	automatically, but needs to determine by the type of machine the package
	259	will run on. Usually, assuming the package is built to be run on the
	260	_same_ architectures, `configure' can figure that out, but if it prints
	261	a message saying it cannot guess the machine type, give it the
	262	`--build=TYPE' option. TYPE can either be a short name for the system
	263	type, such as `sun4', or a canonical name which has the form:
	264
130	265	CPU-COMPANY-SYSTEM
131	266
132		See the file `config.sub' for the possible values of each field. If
	267	where SYSTEM can have one of these forms:
	268
	269	OS
	270	KERNEL-OS
	271
	272	See the file `config.sub' for the possible values of each field. If
133	273	`config.sub' isn't included in this package, then this package doesn't
134		need to know the host type.
135
136		If you are building compiler tools for cross-compiling, you can also
137		use the `--target=TYPE' option to select the type of system they will
138		produce code for and the `--build=TYPE' option to select the type of
139		system on which you are compiling the package.
	274	need to know the machine type.
	275
	276	If you are _building_ compiler tools for cross-compiling, you should
	277	use the option `--target=TYPE' to select the type of system they will
	278	produce code for.
	279
	280	If you want to _use_ a cross compiler, that generates code for a
	281	platform different from the build platform, you should specify the
	282	"host" platform (i.e., that on which the generated programs will
	283	eventually be run) with `--host=TYPE'.
140	284
141	285	Sharing Defaults
142	286	================

149	293	`CONFIG_SITE' environment variable to the location of the site script.
150	294	A warning: not all `configure' scripts look for a site script.
151	295
152		Operation Controls
	296	Defining Variables
153	297	==================
	298
	299	Variables not defined in a site shell script can be set in the
	300	environment passed to `configure'. However, some packages may run
	301	configure again during the build, and the customized values of these
	302	variables may be lost. In order to avoid this problem, you should set
	303	them in the `configure' command line, using `VAR=value'. For example:
	304
	305	./configure CC=/usr/local2/bin/gcc
	306
	307	causes the specified `gcc' to be used as the C compiler (unless it is
	308	overridden in the site shell script).
	309
	310	Unfortunately, this technique does not work for `CONFIG_SHELL' due to
	311	an Autoconf limitation. Until the limitation is lifted, you can use
	312	this workaround:
	313
	314	CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
	315
	316	`configure' Invocation
	317	======================
154	318
155	319	`configure' recognizes the following options to control how it
156	320	operates.
157	321
	322	`--help'
	323	`-h'
	324	Print a summary of all of the options to `configure', and exit.
	325
	326	`--help=short'
	327	`--help=recursive'
	328	Print a summary of the options unique to this package's
	329	`configure', and exit. The `short' variant lists options used
	330	only in the top level, while the `recursive' variant lists options
	331	also present in any nested packages.
	332
	333	`--version'
	334	`-V'
	335	Print the version of Autoconf used to generate the `configure'
	336	script, and exit.
	337
158	338	`--cache-file=FILE'
159		Use and save the results of the tests in FILE instead of
160		`./config.cache'. Set FILE to `/dev/null' to disable caching, for
161		debugging `configure'.
162
163		`--help'
164		Print a summary of the options to `configure', and exit.
	339	Enable the cache: use and save the results of the tests in FILE,
	340	traditionally `config.cache'. FILE defaults to `/dev/null' to
	341	disable caching.
	342
	343	`--config-cache'
	344	`-C'
	345	Alias for `--cache-file=config.cache'.
165	346
166	347	`--quiet'
167	348	`--silent'

174	355	Look for the package's source code in directory DIR. Usually
175	356	`configure' can determine that directory automatically.
176	357
177		`--version'
178		Print the version of Autoconf used to generate the `configure'
179		script, and exit.
180
181		`configure' also accepts some other, not widely useful, options.
	358	`--prefix=DIR'
	359	Use DIR as the installation prefix. *note Installation Names::
	360	for more details, including other options available for fine-tuning
	361	the installation locations.
	362
	363	`--no-create'
	364	`-n'
	365	Run the configure checks, but stop before creating any output
	366	files.
	367
	368	`configure' also accepts some other, not widely useful, options. Run
	369	`configure --help' for more details.

	1699	* protected using a specific system, it first needs all the
	1700	* protection system specific information necessary to acquire the decryption
	1701	* key(s) for that stream. The functions defined here enable this information
	1702	* to be passed in events from elements that extract it
	1703	* (e.g., ISOBMFF demuxers, MPEG DASH demuxers) to protection decrypter
	1704	* elements that use it.
	1705	*
	1706	* Events containing protection system specific information are created using
	1707	* #gst_event_new_protection, and they can be parsed by downstream elements
	1708	* using #gst_event_parse_protection.
	1709	*
	1710	* In Common Encryption, protection system specific information may be located
	1711	* within ISOBMFF files, both in movie (moov) boxes and movie fragment (moof)
	1712	* boxes; it may also be contained in ContentProtection elements within MPEG
	1713	* DASH MPDs. The events created by #gst_event_new_protection contain data
	1714	* identifying from which of these locations the encapsulated protection system
	1715	* specific information originated. This origin information is required as
	1716	* some protection systems use different encodings depending upon where the
	1717	* information originates.
	1718	*
	1719	* The events returned by #gst_event_new_protection are implemented
	1720	* in such a way as to ensure that the most recently-pushed protection info
	1721	* event of a particular @origin and @system_id will
