#### <a name="buildArmNN">Build ArmNN</a>
* Clone ArmNN source code:
-DARMCOMPUTENEON=1 -DARMCOMPUTECL=1 -DARMNNREF=1 \
-DTF_GENERATED_SOURCES=$HOME/armnn-devenv/google/tf_pb/ -DBUILD_TF_PARSER=1 \
-DPROTOBUF_ROOT=$HOME/armnn-devenv/google/arm64_pb_install/
- make -j16
```
+ To include standalone sample dynamic backend tests, add the argument to enable the tests and the dynamic backend path to the CMake command:
+
+ ```bash
+ -DSAMPLE_DYNAMIC_BACKEND=1 \
+ -DDYNAMIC_BACKEND_PATHS=$SAMPLE_DYNAMIC_BACKEND_PATH
+ ```
+ Where $SAMPLE_DYNAMIC_BACKEND_PATH is the path where libArm_SampleDynamic_backend.so library file is pushed
+
+ * Run the build
+ ```bash
+ make -j16
+ ```
+
+#### <a name="buildStandaloneBackend">Build Standalone Sample Dynamic Backend</a>
+* The sample dynamic backend is located in armnn/src/dynamic/sample
+ ```bash
+ mkdir build
+ cd build
+ ```
+
+* Use CMake to configure the build environment, update the following script and run it from the armnn/src/dynamic/sample/build directory to set up the armNN build:
+ ```bash
+ #!/bin/bash
+ CXX=aarch64-linux-android-clang++ \
+ CC=aarch64-linux-android-clang \
+ CXX_FLAGS="-fPIE -fPIC" \
+ cmake \
+ -DCMAKE_SYSTEM_NAME=Android \
+ -DCMAKE_CXX_FLAGS=--std=c++14 \
+ -DCMAKE_EXE_LINKER_FLAGS="-pie -llog" \
+ -DCMAKE_MODULE_LINKER_FLAGS="-llog" \
+ -DBOOST_ROOT=$HOME/armnn-devenv/boost/install \
+ -DBoost_SYSTEM_LIBRARY=$HOME/armnn-devenv/boost/install/lib/libboost_system.a \
+ -DBoost_FILESYSTEM_LIBRARY=$HOME/armnn-devenv/boost/install/lib/libboost_filesystem.a \
+ -DARMNN_PATH=$HOME/armnn-devenv/armnn/build/libarmnn.so ..
+ ```
+
+* Run the build
+ ```bash
+ make
+ ```
+
#### <a name="runArmNNUnitTests">Run the ArmNN unit tests on an Android device</a>
* Push the build results to an Android device and make symbolic links for shared libraries:
+ Currently adb version we have used for testing is 1.0.41.

```
+ If the standalone sample dynamic tests are enabled, also push libArm_SampleDynamic_backend.so library file to the folder specified as $SAMPLE_DYNAMIC_BACKEND_PATH when ArmNN is built.
+ This is the example when $SAMPLE_DYNAMIC_BACKEND_PATH is specified as /data/local/tmp/dynamic/sample/:
+
+ ```bash
+ adb shell mkdir -p /data/local/tmp/dynamic/sample/
+ adb push -p ${WORKING_DIR}/armnn/src/dynamic/sample/build/libArm_SampleDynamic_backend.so /data/local/tmp/dynamic/sample/
+ ```
+
* Run ArmNN unit tests:
```bash
- adb shell 'LD_LIBRARY_PATH=/data/local/tmp /data/local/tmp/UnitTests'
+ adb shell 'LD_LIBRARY_PATH=/data/local/tmp:/vendor/lib64:/vendor/lib64/egl /data/local/tmp/UnitTests'
```
If libarmnnUtils.a is present in `~/armnn-devenv/armnn/build/` and the unit tests run without failure then the build was successful.
