最近用到视频格式转码，发现谷歌的开源库 libyuv 很好用，所以记录下编译过程

直接贴 官网的编译流程

https://chromium.googlesource.com/libyuv/libyuv/+/master/docs/getting_started.md

不过我得吐槽一下，我特么就想编译个libyuv 你特么非要让我把chrome项目check 下来是几个意思。。。。如果没猜错 应该是好几个g

Getting Started

How to get and build the libyuv code.

Pre-requisites

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

Building the Library and Unittests

Windows

Building
 with clangcl

OSX

Clang 64 bit shown. Remove clang=1 for GCC and change x64 to ia32 for 32 bit.

iOS

http://www.chromium.org/developers/how-tos/build-instructions-ios

Add to .gclient last line: target_os=['ios'];

armv7

arm64

both armv7 and arm64 (fat)

simulator

Android

https://code.google.com/p/chromium/wiki/AndroidBuildInstructions

Add to .gclient last line: target_os=['android'];

armv7

arm64

ia32

mipsel

arm32 disassembly:

arm64 disassembly:

Running tests:

Running test as benchmark:

Running test with C code:

Building
 with GN

Building
 Offical with GN

Linux

CentOS

On CentOS 32 bit the following work around allows a sync:

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
 the Library with make

Linux

Building
 the Library with cmake

Install cmake: http://www.cmake.org/

Default debug build:

Release build/install

Windows
 8 Phone

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.

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

64 bit Windows

ARM
 Linux

export GYP_DEFINES="target_arch=arm"
export CROSSTOOL=`<path>`/arm-none-linux-gnueabi
export CXX=$CROSSTOOL-g++
export CC=$CROSSTOOL-gcc
export AR=$CROSSTOOL-ar
export AS=$CROSSTOOL-as
export RANLIB=$CROSSTOOL-ranlib
gclient runhooks

Running Unittests

Windows

OSX

Linux

Replace --gtest_filter=“*” with specific unittest to run. May include wildcards. e.g.

CPU
 Emulator tools

Intel SDE (Software Development Emulator)

Pre-requisite: Install IntelSDE for Windows: http://software.intel.com/en-us/articles/intel-software-development-emulator

Then run:

Memory
 tools

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:

For more information, see http://www.chromium.org/developers/how-tos/using-valgrind

Running Thread Sanitizer (TSan)

For more info, see http://www.chromium.org/developers/how-tos/using-valgrind/threadsanitizer

Running Address Sanitizer (ASan)

For more info, see http://dev.chromium.org/developers/testing/addresssanitizer

Benchmarking

The unittests can be used to benchmark.
