在OSX上使用python 3.5.0使用pyenv编译OpenCV3

Question

花了我一段时间来解决这个问题，所以我想我会写下来。

Answer 1

通过pyenv安装具有共享库支持的python：

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.5.0

新建一个名为opencv的virtualenv

pyenv virtualenv 3.5.0 opencv

激活virtualenv并安装numpy

pyenv activate opencv
pyenv rehash
pip install numpy

克隆opencv和opencv_contrib并将其放入〜/

cd ~
git clone https://github.com/Itseez/opencv.git
cd opencv
git checkout 3.1.0

cd ~
git clone https://github.com/Itseez/opencv_contrib
cd opencv_contrib
git checkout 3.1.0

cd ~/opencv
mkdir build
cd build

运行CMake并安装

PREFIX_MAIN=`pyenv virtualenv-prefix`
PREFIX=`pyenv prefix`
cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX="$PREFIX" \
    -D PYTHON3_EXECUTABLE="$PREFIX"/bin/python3.5 \
    -D PYTHON3_PACKAGES_PATH="$PREFIX"/lib/python3.5/site-packages \
    -D PYTHON3_LIBRARY="$PREFIX_MAIN"/lib/libpython3.5m.dylib \
    -D PYTHON3_INCLUDE_DIR="$PREFIX_MAIN"/include/python3.5m \
    -D PYTHON3_NUMPY_INCLUDE_DIRS="$PREFIX"/lib/python3.5/site-packages/numpy/core/include \
    -D INSTALL_C_EXAMPLES=OFF \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_opencv_python3=ON \
    -D INSTALL_NAME_DIR=${CMAKE_INSTALL_PREFIX}/lib \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

make -j8

make install

注意：如果您使用的是python 3.5.2，则需要进行更改

PYTHON3_EXECUTABLE="$PREFIX"/bin/python3
PYTHON3_LIBRARY="$PREFIX_MAIN"/lib/libpython3.5m.a
