Pre-requisites You'll need to have depot tools installed:https://www.chromium.org/developers/how-tos/install-depot-toolsRefer 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 addios'];to your OSX .gclient and run Browse the Git reprository:https://chromium.googlesource.com/libyuv/libyuv/+/master Android For Android addandroid'];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 clonehttps://chromium.googlesource.com/libyuv/libyuv Building the Library and Unittests Windows Building with clangcl OSX Clang 64 bit shown. Removeclang=1for 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, readhttp://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, readhttp://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]1is 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, seehttp://www.chromium.org/developers/how-tos/using-valgrind Running Thread Sanitizer (TSan) For more info, seehttp://www.chromium.org/developers/how-tos/using-valgrind/threadsanitizer Running Address Sanitizer (ASan) For more info, seehttp://dev.chromium.org/developers/testing/addresssanitizer Benchmarking The unittests can be used to benchmark. Windows Linux and Mac Indicates 0.547 ms/frame for 1280 x 720.
