Older documentation on build configs which are no longer supported.
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.
Create a working directory, enter it, and run:
gclient config https://chromium.googlesource.com/libyuv/libyuv
gclient sync
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 ;target_os=['ios'];
to your OSX .gclient and run GYP_DEFINES="OS=ios" gclient sync.
Browse the Git reprository: https://chromium.googlesource.com/libyuv/libyuv/+/master
For Android add ;target_os=['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:
export GYP_DEFINES="OS=android"
gclient sync
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: gclient runhooks
To get just the source (not buildable):
git clone https://chromium.googlesource.com/libyuv/libyuv

On CentOS 32 bit the following work around allows a sync:
export GYP_DEFINES="host_arch=ia32"
gclient sync
Modify libyuv.gyp from 'static_library' to 'shared_library', and add 'LIBYUV_BUILDING_SHARED_LIBRARY' to 'defines'.
gclient runhooks

Memory errors and race conditions can be found by running tests under special memory tools. Valgrind 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.
