You'll need to have depot tools installed: https://www.chromium.org/developers/how-tos/install-depot-tools Refer
to chromium instructions for each platform for other prerequisites.

说明：依赖工具，谷歌的这套东西还是比较好用的，首先要安装depottools 这点不多说，命令行就行，最重要的是在下载完成之后要有

export PATH=`pwd`/depot_tools:"$PATH" 命令使能这个工具

Getting
the Code

Create a working directory, enter it, and run:

说明：设置与同步代码，里面自带脚本，关于代码如何同步的就无需关心了。

Then you'll get a .gclient file like:

solutions = [

  { "name"        : "libyuv",

    "url"         : "https://chromium.googlesource.com/libyuv/libyuv",

    "deps_file"   : "DEPS",

    "managed"     : True,

    "custom_deps" : {

    },

    "safesync_url": "",

  },

];

For iOS add ios']; to your OSX .gclient and run Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master

Android

For Android add android']; to your Linux .gclient

solutions = [

  { "name"        : "libyuv",

    "url"         : "https://chromium.googlesource.com/libyuv/libyuv",

    "deps_file"   : "DEPS",

    "managed"     : True,

    "custom_deps" : {

    },

    "safesync_url": "",

  },

];

target_os = ["android", "unix"];

Then run:

Caveat: Theres an error with Google Play services updates. If you get

the error “Your version of the Google Play services library is not up to

 date”, run the following: cd chromium/src

./build/android/play_services/update.py download cd ../..

For Windows the gclient sync must be done from an Administrator command prompt.

The sync will generate native build files for your environment using gyp (Windows: Visual Studio, OSX: XCode, linux: make). This generation can also be forced manually: To get just the source (not buildable): git clone https://chromium.googlesource.com/libyuv/libyuv

Windows

 Shared Library

Modify libyuv.gyp from ‘static_library’ to ‘shared_library’, and add ‘LIBYUV_BUILDING_SHARED_LIBRARY’ to ‘defines’.

After this command follow the building the library instructions above.

If you get a compile error for atlthunk.lib on Windows, read http://www.chromium.org/developers/how-tos/build-instructions-windows

Build targets

Building

Pre-requisite:

Install Visual Studio 2012 and Arm to your environment.

Then:

or with Visual Studio 2013:

Windows

 Shared Library

Modify libyuv.gyp from ‘static_library’ to ‘shared_library’, and add ‘LIBYUV_BUILDING_SHARED_LIBRARY’ to ‘defines’. Then run this.

Running Dr Memory memcheck for Windows

Pre-requisite: Install Dr Memory for Windows and add it to your path: http://www.drmemory.org/docs/page_install_windows.html

Running

 UBSan

See Chromium instructions for sanitizers: https://www.chromium.org/developers/testing/undefinedbehaviorsanitizer

Sanitizers available: TSan, MSan, ASan, UBSan, LSan

Running

 Valgrind memcheck

Memory errors and race conditions can be found by running tests under special memory tools. [Valgrind] 1 is an instrumentation framework for building dynamic analysis tools. Various tests and profilers are built upon it to find memory handling errors and memory leaks, for instance.

Then run:
