我一直在我的Ubuntu 16.10工作站上为Python 3.6m编译和安装OpenCV 3.2.0。
不幸的是,我收到以下错误:
user@host ~/D/o/cmake> python3 -c "import cv2"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: /usr/local/lib/python3.6/dist-packages/cv2.cpython-36m-x86_64-linux-gnu.so:
undefined symbol: _Z13pyopencv_fromIN2cv4MatxIdLi4ELi4EEEEP7_objectRKT_
我一直在配置cmake
,如下所示:
cmake \
-D BUILD_opencv_python3=ON \
-D HAVE_opencv_python3=ON \
-D PYTHON3LIBS_VERSION_STRING=3.6m \
-D PYTHON3_LIBRARIES=/usr/lib/x86_64-linux-gnu/libpython3.6m.so \
-D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6im.so \
-D PYTHON3_INCLUDE_PATH=/usr/include/python3.6m \
-D PYTHON3_INCLUDE_DIR=/usr/include/python3.6m \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D BUILD_NEW_PYTHON_SUPPORT=ON \
-D INSTALL_C_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-DENABLE_PRECOMPILED_HEADERS=OFF \
-D OPENCV_EXTRA_MODULES_PATH=/home/user/Downloads/opencv_contrib/modules ..
有什么可能导致未定义符号的想法?
这可能与ldconfig
相关吗?
