If you are using Ubuntu 20.04 the command given in Initial Setup should install a usable version. Install CmakeĬmake 3.19rc3 or later is required to build Arm NN. Android's current preference is for you to just specify the architecture and operating system while setting the compiler and just use the ndk directory. With Android NDK-25, you no longer need to use the make_standalone_toolchain script to create a toolchain for a specific version of Android. com / android / repository / android - ndk - r25 - linux. # For Mac OS, change the NDK download link accordingly. If this has not been already installed then install it using: sudo apt install cmakeĭownload the Android NDK and make a standalone toolchainĭownload the Android NDK from the official website: mkdir - p $WORKING_DIR If this has not been already installed then install it using: sudo apt install sconsĬMake is required to build Arm NN and its dependencies. If this has not been already installed then install it using: sudo apt install gitĪrm Compute Library requires SCons. The WORKING_DIR can be any directory you have write permissions to. The ANDROID_API variable should be set to the Android API version number you are using. You may want to append the above export variables commands to your ~/.bashrc (or ~/.bash_profile in macOS). export ANDROID_API = 30Įxport WORKING_DIR = $HOME / armnn - devenvĮxport NDK_DIR = $WORKING_DIR / android - ndk - r25Įxport NDK_TOOLCHAIN_ROOT = $NDK_DIR / toolchains / llvm / prebuilt / linux - x86_64Įxport PATH = $NDK_TOOLCHAIN_ROOT / bin /: $PATH Initial Setupįirst, we need to specify the Android version and the directories you want to build Arm NN in and to install some applications required to build Arm NN and its dependencies. BASE_DIR is path to the script file, which is armnn/scripts/. The shell script version of this guide (build_android_ndk_guide.sh) also provides user the option to use the Arm NN and ComputeLibrary available in your BASE_DIR, instead of downloading a new version. Run the script with a -h flag to see the command line parameters. The instructions show how to build the Arm NN core library and its dependencies.įor ease of use there is a shell script version of this guide located in the scripts directory called build_android_ndk_guide.sh. They have been tested on a clean installation of Ubuntu 18.04 and 20.04, and should also work with other OS versions. These are step-by-step instructions for using the Android NDK to build Arm NN. Run the Arm NN unit tests on an Android device. ![]()
