@H_502_0@如果在Ubuntu下，Python环境是Anaconda的时候编译OpenCV，直接cmake会有问题，cmake会找到系统自带的Python2的python lib而不是Anaconda里面的，两个python版本号不一样就不会编译python接口。

@H_502_0@解决方法是在cmake命令里指定python2环境的参数。

@H_502_0@先在opencv的源码目录里新建一个build文件夹，然后进入这个文件夹，执行下面的命令：

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \ 
    -D PYTHON_INCLUDE_DIR=/PATH_TO_ANACONDA/anaconda2/include/python2.7 \
    -D PYTHON_INCLUDE_DIR2=/PATH_TO_ANACONDA/anaconda2/include/python2.7 \
    -D PYTHON_LIBRARY=/PATH_TO_ANACONDA/anaconda2/lib/libpython2.7.so \
    -D PYTHON2_LIBRARY=/PATH_TO_ANACONDA/anaconda2/lib/libpython2.7.so \
    -D PYTHON_PACKAGES_PATH=/PATH_TO_ANACONDA/anaconda2/lib/python2.7/site-packages/ \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_NEW_PYTHON_SUPPORT=ON \
    -D BUILD_opencv_python3=OFF \
    -D BUILD_opencv_python2=ON \
    -D BUILD_TIFF=ON ..

之后执行

make
sudo make install
