Build Tengine

Environmental requirements

  • opencv >= 3.4

  • cmake >= 3.10

  • protobuf >= 3.0

  • gcc >= 4.9

  • ndk >= 15c （If Use Android）

Build Linux version

  1. clone Tengine project，git clone https://github.com/OAID/Tengine.git

  2. build dynamic library.

cd Tengine
mkdir build && cd build
cmake .. && make -j4
make install

After the compilation is complete, the build/install/lib directory will generate a libtengine-lite.so file, as shown below:

install
├── bin
│   ├── tm_benchmark
│   ├── tm_classification
│   └── tm_mobilenet_ssd
├── include
│   └── tengine_c_api.h
└── lib
    └── libtengine-lite.so

Build Androidv7/v8 version

Download ndk, http://developer.android.com/ndk/downloads/index.html (Optional) Delete the debug parameter to reduce the binary size. The file android.toolchain.cmake can be found from $ANDROID_NDK/build/cmake.

# vim $ANDROID_NDK/build/cmake/android.toolchain.cmake
# delete "-g" line
list(APPEND ANDROID_COMPILER_FLAGS
  -g
  -DANDROID

Configuration Environment:

export $ANDROID_NDK=<NDK-path>

Android v7 build command:

mkdir build-android-armv7
cd build-android-armv7
cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake -DANDROID_ABI="armeabi-v7a" -DANDROID_ARM_NEON=ON -DANDROID_PLATFORM=android-19 ..
make
make install

Android v8 build command：

mkdir build-android-aarch64
cd build-android-aarch64
cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build-android-aarch64/cmake/android.toolchain.cmake -DANDROID_ABI="arm64-v8a" -DANDROID_PLATFORM=android-21 ..
make
make install

After successful compilation, copy libtengine-lite.so to <Tengine-Factory-path>/libs
