在 centos 上为 python 从源代码安装 opencv

Question

我安装了CentOS6.5。我安装了 python 2.7.9。我从源代码构建它。使用 pip 安装的 numpy 1.9.1。

我正在尝试从源代码安装 opencv 2.4.10。我运行使用 root 权限从 opencv src 目录执行命令。

mkdir build

cd build

cmake ../ -DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DBUILD_EXAMPLES=ON \
-DBUILD_NEW_PYTHON_SUPPORT=ON \
-DINSTALL_PYTHON_EXAMPLES=ON \
-DPYTHON_EXECUTABLE=/usr/local/bin/python2.7 \
-DPYTHON_INCLUDE_DIR=/usr/local/include/python2.7/ \
-DPYTHON_LIBRARY=/usr/local/lib/libpython2.7.so.1.0 \
-DPYTHON_NUMPY_INCLUDE_DIR=/usr/local/lib/python2.7/site-packages/numpy/core/include/numpy \
-DPYTHON_PACKAGES_PATH=/usr/local/lib/python2.7/site-packages/ \
-DBUILD_PYTHON_SUPPORT=ON


make

我遇到以下错误。

你能帮忙吗？

我使用“--enable-shared”标志构建 python 我注释掉了第 50 行 string(MD5 hash "${lines}") /usr/src/opencv- 2.4.10/cmake/cl2cpp.cmake

Answer 1

-DPYTHON_NUMPY_INCLUDE_DIR=/usr/local/lib/python2.7/site-packages/numpy/core/include

去掉拖尾/numpy应该没问题。
