Paweł Hajdan9ab47772013-08-01 20:08:42 -0700[diff] [blame]3Welcome to the WebM VP8/VP9 Codec SDK!

5COMPILING THE APPLICATIONS/LIBRARIES:
6 The build system used is similar to autotools. Building generally consists of
7 "configuring" with your desired build options, then using GNU make to build
8 the application.

John Koleszar94c52e42010-06-18 12:39:21 -0400[diff] [blame]11
John Koleszar0ea50ce2010-05-18 11:58:33 -0400[diff] [blame]12 * All x86 targets require the Yasm[1] assembler be installed.
13 * All Windows builds require that Cygwin[2] be installed.
James Zernf8630c72014-05-10 11:15:11 -0700[diff] [blame]14 * Building the documentation requires Doxygen[3]. If you do not
15 have this package, the install-docs option will be disabled.
16 * Downloading the data for the unit tests requires curl[4] and sha1sum.
John Koleszar00748632012-06-20 14:45:22 -0700[diff] [blame]17 sha1sum is provided via the GNU coreutils, installed by default on
18 many *nix platforms, as well as MinGW and Cygwin. If coreutils is not
19 available, a compatible version of sha1sum can be built from
James Zernf8630c72014-05-10 11:15:11 -0700[diff] [blame]20 source[5]. These requirements are optional if not running the unit
John Koleszar00748632012-06-20 14:45:22 -0700[diff] [blame]21 tests.

30 Out of tree builds are a supported method of building the application. For
31 an out of tree build, the source tree is kept separate from the object
32 files produced during compilation. For instance:
33
34 $ mkdir build
35 $ cd build
36 $ ../libvpx/configure <options>
37 $ make
38
39 3. Configuration options
40 The 'configure' script supports a number of options. The --help option can be
41 used to get a list of supported options:
42 $ ../libvpx/configure --help
43
44 4. Cross development
45 For cross development, the most notable option is the --target option. The
46 most up-to-date list of supported targets can be found at the bottom of the
47 --help output of the configure script. As of this writing, the list of
48 available targets is:

117
118 The generic-gnu target, in conjunction with the CROSS environment variable,
119 can be used to cross compile architectures that aren't explicitly listed, if
120 the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains
121 will likely work as well. For instance, to build using the mipsel-linux-uclibc
122 toolchain, the following command could be used (note, POSIX SH syntax, adapt
123 to your shell as necessary):
124
Johanna31a58d2010-10-07 14:13:36 -0400[diff] [blame]125 $ CROSS=mipsel-linux-uclibc- ../libvpx/configure
John Koleszar0ea50ce2010-05-18 11:58:33 -0400[diff] [blame]126
127 In addition, the executables to be invoked can be overridden by specifying the
128 environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be
129 passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.
130
131 5. Configuration errors
132 If the configuration step fails, the first step is to look in the error log.
James Zerne636af12013-07-18 14:17:00 -0700[diff] [blame]133 This defaults to config.log. This should give a good indication of what went
John Koleszar0ea50ce2010-05-18 11:58:33 -0400[diff] [blame]134 wrong. If not, contact us for support.

James Zern4bbca2e2014-05-30 16:37:39 -0700[diff] [blame]136VP8/VP9 TEST VECTORS:
137 The test vectors can be downloaded and verified using the build system after
138 running configure. To specify an alternate directory the
139 LIBVPX_TEST_DATA_PATH environment variable can be used.
140
141 $ ./configure --enable-unit-tests
142 $ LIBVPX_TEST_DATA_PATH=../libvpx-test-data make testdata
