I install OpenCV 4.0.1 followed Raspbian Stretch: Install OpenCV 3 + Python on your Raspberry Pi , successfully compiled and installed on my raspberry. But when I want compiled Opencv with Inference Engine backend, got some error.
my env:
- Raspberry 3b+
- OS: Raspbian 9.8
- Python: 3.5.3
- GCC: 6.3.0
- Make: 4.1
- Cmake: 3.7.2
Here is my code:
install dependencies(python’s dep already done):
bash
sudo apt-get install \
cmake pkg-config \
libjpeg-dev libtiff5-dev libjasper-dev \
libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
libxvidcore-dev libx264-dev \
libgtk2.0-dev libgtk-3-dev \
libatlas-base-dev gfortran \
build-essential \
xz-utils \
libgtk2.0-dev:armhf \
libgstreamer1.0-dev:armhf \
libgstreamer-plugins-base1.0-dev:armhf
cmake param:
bash
cmake -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX="../opencv_install" \
-DOPENCV_CONFIG_INSTALL_PATH="cmake" \
-DWITH_IPP=OFF \
-DBUILD_TESTS=OFF \
-DBUILD_PERF_TESTS=OFF \
-DPYTHON3_EXECUTABLE=/usr/bin/python3.5 \
-DPYTHON3_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython3.5m.so \

-DPYTHON3_CVPY_SUFFIX=".cpython-35m-arm-linux-gnueabihf.so" \
-DENABLE_NEON=ON \

-DWITH_INF_ENGINE=ON \
-DINF_ENGINE_LIB_DIRS="/home/pi/inference_engine_vpu_arm/deployment_tools/inference_engine/lib/raspbian_9/armv7l" \
-DINF_ENGINE_INCLUDE_DIRS="/home/pi/inference_engine_vpu_arm/deployment_tools/inference_engine/include" \
-DCMAKE_FIND_ROOT_PATH="/home/pi/inference_engine_vpu_arm/" \
-DENABLE_CXX11=ON ..
then make -j4, come out a error:
