Build

We use CMake build system like most C++ projects.

Clone the project

Clone dabnn recursively

git clone --recursive https://github.com/JDAI-CV/dabnn

Build dabnn

Cross-compiling for ARMv8 Android:

  1. Download and unzip Android NDK from https://developer.android.com/ndk/downloads.

  2. Run cmake with the toolchain file, which determine the proper compiling toolchains. If this step fails, please check whether the toolchain file really exists on the path you set.

mkdir build-dabnn
cd build-dabnn
cmake -DCMAKE_TOOLCHAIN_FILE=the_path_to_android_ndk/build/cmake/android.toolchain.cmake -DANDROID_ABI=arm64-v8a -DCMAKE_BUILD_TYPE=Release ..
  1. Build
cmake --build .

For ARMv7, just replace -DANDROID_ABI=arm64-v8a with -DANDROID_ABI=armeabi-v7a in step 2.

For non-Android ARM devices, use the proper toolchain file for your device instead of the Android NDK toolchain file, or compile natively on your ARM device.

For non-ARM devices, only the unoptimized code will work. If you still want to build dabnn for non-ARM devices, pass -DBNN_BUILD_MAIN_LIB=ON in step 2.

Build onnx2bnn

On non-ARM devices, just run cmake and build the project directly.

  1. Run cmake
mkdir build-onnx2bnn
cd build-onnx2bnn
cmake ..
  1. Build
cmake --build .

On ARM devices, pass -DBNN_BUILD_MAIN_LIB=OFF in step 1.
