Building generally consists of\n  \"configuring\" with your desired build options, then using GNU make to build\n  the application.\n\n  1. Prerequisites\n\n    * All x86 targets require the Yasm[1] assembler be installed.\n    * All Windows builds require that Cygwin[2] be installed.\n    * Building the documentation requires Doxygen[3]. If you do not\n      have this package, the install-docs option will be disabled.\n    * Downloading the data for the unit tests requires curl[4] and sha1sum.\n      sha1sum is provided via the GNU coreutils, installed by default on\n      many *nix platforms, as well as MinGW and Cygwin. If coreutils is not\n      available, a compatible version of sha1sum can be built from\n      source[5]. These requirements are optional if not running the unit\n      tests.\n\n    [1]: http://www.tortall.net/projects/yasm\n    [2]: http://www.cygwin.com\n    [3]: http://www.doxygen.org\n    [4]: http://curl.haxx.se\n    [5]: http://www.microbrew.org/tools/md5sha1sum/\n\n  2. Out-of-tree builds\n  Out of tree builds are a supported method of building the application. For\n  an out of tree build, the source tree is kept separate from the object\n  files produced during compilation. For instance:\n\n    $ mkdir build\n    $ cd build\n    $ ../libaom/configure \u003coptions\u003e\n    $ make\n\n  3. Configuration options\n  The 'configure' script supports a number of options. The --help option can be\n  used to get a list of supported options:\n    $ ../libaom/configure --help\n\n  4. Cross development\n  For cross development, the most notable option is the --target option. The\n  most up-to-date list of supported targets can be found at the bottom of the\n  --help output of the configure script. As of this writing, the list of\n  available targets is:\n\n    arm64-darwin-gcc\n    armv7-android-gcc\n    armv7-darwin-gcc\n    armv7-linux-rvct\n    armv7-linux-gcc\n    armv7-none-rvct\n    armv7-win32-vs12\n    armv7-win32-vs14\n    armv7s-darwin-gcc\n    mips32-linux-gcc\n    mips64-linux-gcc\n    sparc-solaris-gcc\n    x86-android-gcc\n    x86-darwin8-gcc\n    x86-darwin8-icc\n    x86-darwin9-gcc\n    x86-darwin9-icc\n    x86-darwin10-gcc\n    x86-darwin11-gcc\n    x86-darwin12-gcc\n    x86-darwin13-gcc\n    x86-darwin14-gcc\n    x86-darwin15-gcc\n    x86-darwin16-gcc\n    x86-iphonesimulator-gcc\n    x86-linux-gcc\n    x86-linux-icc\n    x86-os2-gcc\n    x86-solaris-gcc\n    x86-win32-gcc\n    x86-win32-vs12\n    x86-win32-vs14\n    x86_64-android-gcc\n    x86_64-darwin9-gcc\n    x86_64-darwin10-gcc\n    x86_64-darwin11-gcc\n    x86_64-darwin12-gcc\n    x86_64-darwin13-gcc\n    x86_64-darwin14-gcc\n    x86_64-darwin15-gcc\n    x86_64-darwin16-gcc\n    x86_64-iphonesimulator-gcc\n    x86_64-linux-gcc\n    x86_64-linux-icc\n    x86_64-solaris-gcc\n    x86_64-win64-gcc\n    x86_64-win64-vs12\n    x86_64-win64-vs14\n    generic-gnu\n\n  The generic-gnu target, in conjunction with the CROSS environment variable,\n  can be used to cross compile architectures that aren't explicitly listed, if\n  the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains\n  will likely work as well. For instance, to build using the mipsel-linux-uclibc\n  toolchain, the following command could be used (note, POSIX SH syntax, adapt\n  to your shell as necessary):\n\n    $ CROSS=mipsel-linux-uclibc- ../libaom/configure\n\n  In addition, the executables to be invoked can be overridden by specifying the\n  environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be\n  passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.\n\n  5. Configuration errors\n  If the configuration step fails, the first step is to look in the error log.\n  This defaults to config.log. This should give a good indication of what went\n  wrong. If not, contact us for support.\n\nAV1 TEST VECTORS:\n  The test vectors can be downloaded and verified using the build system after\n  running configure. To specify an alternate directory the\n  LIBAOM_TEST_DATA_PATH environment variable can be used.\n\n  $ ./configure --enable-unit-tests\n  $ LIBAOM_TEST_DATA_PATH=../-test-data make testdata\n\nUNIT TESTS:\n  The unit tests (consisting mainly of the test_libaom binary) can be run using\n  make. This will download the test data if necessary.\n\n  $ ../libaom/configure --enable-unit-tests\n  $ make test\n\n  Test may be run in parallel using make -j which supports up to 10 shards by\n  default.\n  $ make -j10 test\n\n  If you have additional cores you can scale the tests to match:\n  $ shards=$(nproc); \\\n    make -j$shards test \\\n    NUM_SHARDS=$shards SHARDS=\"$(seq -s' ' 0 $(( shards - 1 )))\" \\\n    \u0026\u0026 echo \"success\"\n\n  The GTEST_FILTER environment variable (equivalent to --gtest_filter) can be\n  used to control which tests are run while sharding:\n  $ GTEST_FILTER='SSE2*' make -j10 test\n\nCODE STYLE:\n  The coding style used by this project is enforced with clang-format using the\n  configuration contained in the .clang-format file in the root of the\n  repository.\n\n  Before pushing changes for review you can format your code with:\n  # Apply clang-format to modified .c, .h and .cc files\n  $ clang-format -i --style=file \\\n    $(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')\n\n  Check the .clang-format file for the version used to generate it if there is\n  any difference between your local formatting and the review system.\n\n  See also: http://clang.llvm.org/docs/ClangFormat.html\n\nSUPPORT\n  This library is an open source project supported by its community.
