Question

我正在尝试从源代码中构建OpenCV 3.4.3，并且正在创建一个用于Python代码的库。我看到以下错误：

import vision_library
ImportError: dlopen(/home/ssk/pyVision/python_scripts/vision_library.so, 2): Symbol not found: ___itt_api_version_ptr__3_0
  Referenced from: /home/ssk/pyVision/python_scripts/vision_library.so
  Expected in: flat namespace

这是CMAKE构建命令：

# Set Build Variables
PYTHON2_EXECUTABLE='/usr/local/Frameworks/Python.framework/Versions/2.7/bin/python2.7'
PYTHON2_INCLUDE_DIR='/usr/local/Frameworks/Python.framework/Versions/2.7/include/python2.7'
PYTHON2_LIBRARY='/usr/local/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib' # TODO - Fix for linux
PYTHON2_NUMPY_INCLUDE_DIRS='/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/core/include' # Todo - Fix for linux


cd $OPENCV_DIR

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=$OPENCV_INSTALL_PATH \
                                  -D WITH_CUDA=OFF \
                                  -D WITH_IPP=OFF \
                                  -D WITH_CLP:BOOL=ON \
                                  -D BUILD_opencv_python2:BOOL=ON \
                                  -D PYTHON2_EXECUTABLE=$PYTHON2_EXECUTABLE \
                                  -D PYTHON2_INCLUDE_DIR=$PYTHON2_INCLUDE_DIR \
                                  -D PYTHON2_LIBRARY=$PYTHON2_LIBRARY \
                                  -D PYTHON2_NUMPY_INCLUDE_DIRS=$PYTHON2_NUMPY_INCLUDE_DIRS \
                                  -D INSTALL_PYTHON_EXAMPLES:BOOL=ON \
                                  -D BUILD_SHARED_LIBS=OFF \
                                  ..
make -j8
make install

如何禁用ITT？我不需要使用它。

Answer 1

可以通过以上命令禁用ITT：

-D WITH_ITT=OFF \
