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.
9
10 1. Prerequisites
11
12 * All x86 targets require the Yasm[1] assembler be installed[2].
13 * All Windows builds require that Cygwin[3] or MSYS2[4] be installed.
14 * Building the documentation requires Doxygen[5]. 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[6] and sha1sum.
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
20 source[7]. These requirements are optional if not running the unit
21 tests.
22
23 [1]: http://www.tortall.net/projects/yasm
24 [2]: For Visual Studio the base yasm binary (not vsyasm) should be in the
25 PATH for Visual Studio. For VS2017 it is sufficient to rename
26 yasm-<version>-<arch>.exe to yasm.exe and place it in:
27 Program Files (x86)/Microsoft Visual Studio/2017/<level>/Common7/Tools/
28 [3]: http://www.cygwin.com
29 [4]: http://www.msys2.org/
30 [5]: http://www.doxygen.org
31 [6]: http://curl.haxx.se
32 [7]: http://www.microbrew.org/tools/md5sha1sum/
33
34 2. Out-of-tree builds
35 Out of tree builds are a supported method of building the application. For
36 an out of tree build, the source tree is kept separate from the object
37 files produced during compilation. For instance:
38
39 $ mkdir build
40 $ cd build
41 $ ../libvpx/configure <options>
42 $ make
43
44 3. Configuration options
45 The 'configure' script supports a number of options. The --help option can be
46 used to get a list of supported options:
47 $ ../libvpx/configure --help
48
49 4. Compiler analyzers
50 Compilers have added sanitizers which instrument binaries with information
51 about address calculation, memory usage, threading, undefined behavior, and
52 other common errors. To simplify building libvpx with some of these features
53 use tools/set_analyzer_env.sh before running configure. It will set the
54 compiler and necessary flags for building as well as environment variables
55 read by the analyzer when testing the binaries.
56 $ source ../libvpx/tools/set_analyzer_env.sh address
57
58 5. Cross development
59 For cross development, the most notable option is the --target option. The
60 most up-to-date list of supported targets can be found at the bottom of the
61 --help output of the configure script. As of this writing, the list of
62 available targets is:

125 x86_64-win64-vs15
126 x86_64-win64-vs16
127 generic-gnu
128
129 The generic-gnu target, in conjunction with the CROSS environment variable,
130 can be used to cross compile architectures that aren't explicitly listed, if
131 the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains
132 will likely work as well. For instance, to build using the mipsel-linux-uclibc
133 toolchain, the following command could be used (note, POSIX SH syntax, adapt
134 to your shell as necessary):
135
136 $ CROSS=mipsel-linux-uclibc- ../libvpx/configure
137
138 In addition, the executables to be invoked can be overridden by specifying the
139 environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be
140 passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.
141
142 6. Configuration errors
143 If the configuration step fails, the first step is to look in the error log.
144 This defaults to config.log. This should give a good indication of what went
145 wrong. If not, contact us for support.
146
147VP8/VP9 TEST VECTORS:
148 The test vectors can be downloaded and verified using the build system after
149 running configure. To specify an alternate directory the
150 LIBVPX_TEST_DATA_PATH environment variable can be used.
151
152 $ ./configure --enable-unit-tests
153 $ LIBVPX_TEST_DATA_PATH=../libvpx-test-data make testdata
154
155CODE STYLE:
156 The coding style used by this project is enforced with clang-format using the
157 configuration contained in the .clang-format file in the root of the
158 repository.
159
160 Before pushing changes for review you can format your code with:
161 # Apply clang-format to modified .c, .h and .cc files
162 $ clang-format -i --style=file \
163 $(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
164
165 Check the .clang-format file for the version used to generate it if there is
166 any difference between your local formatting and the review system.
