+# Deprecated Builds
+
+Older documentation on build configs which are no longer supported.
+
+## 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.
+
+## Getting the Code
+
+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
+
+### Android
+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
+

+
+### 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.
