我正在尝试为我的anaconda3安装构建opencv 3.1.0,我的构建失败了：
[ 94%] Building CXX object modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o /home/mikel/Soft/opencv/modules/python/src2/cv2.cpp:6:20: Fatal error: Python.h: No such file or directory compilation terminated.
我有opencv和opencv-contrib通过使用git checkout 3.1.0克隆版本3.1.0并且我正在尝试构建〜/ Soft / opencv / build,其中我在〜/ Soft / opencv-contrib中有opencv-contrib .我正在使用i7-4960X运行Ubuntu GNOME 15.10.
我的主要目标是在我的anaconda3安装中使opencv工作,所以我的cmake命令如下：
cmake \ -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D INSTALL_C_EXAMPLES=OFF \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D OPENCV_EXTRA_MODULES_PATH=~/Soft/opencv_contrib/modules \ -D python3_EXECUTABLE=/home/mikel/anaconda3/bin/python3.5 \ -D python3_INCLUDE_DIR=/home/mikel/anaconda3/include/ \ -D python3_LIBRARY=/home/mikel/anaconda3/lib/libpython3.5m.so \ -D python3_PACKAGES_PATH=/home/mikel/anaconda3/lib/python3.5/site-packages/ \ -D python3_NUMPY_INCLUDE_Dirs=/home/mikel/anaconda3/lib/python3.5/site-packages/numpy/core/include \ -D PYTHON_DEFAULT_AVAILABLE=/home/mikel/anaconda3/bin/python3.5 \ -D BUILD_EXAMPLES=ON ..
我的cmake命令的输出在这里：http://pastebin.com/qtd1wyMb – 就我所见,一切都还可以.
然后我运行make -j12来安装opencv并在几次警告之后运行正常,直到94％,我得到以下输出：

看起来我的问题是因为我使用anaconda3路径而不是标准的python3路径,它再也找不到Python.h了.但是,当我使用系统python3安装安装时,我无法将opencv导入我需要它的anaconda.
我安装了python3-dev和python-dev,所以Python.h应该在我的机器上.为了使openCV找到Python.h,我需要更改什么？
编辑：我发现Anaconda3的Python.h在anaconda3 / include / python3.5m /所以我设置python3_INCLUDE_DIR = anaconda3 / include / python3.5m /现在我得到一个不同的错误：
Scanning dependencies of target opencv_python3 Linking CXX executable ../../bin/opencv_test_optflow [ 91%] Building CXX object modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o In file included from /home/mikel/Soft/opencv/build/modules/python3/pyopencv_generated_include.h:11:0,from /home/mikel/Soft/opencv/modules/python/src2/cv2.cpp:12: /home/mikel/Soft/opencv_contrib/modules/hdf/include/opencv2/hdf/hdf5.hpp:40:18: Fatal error: hdf5.h: No such file or directory compilation terminated. modules/python3/CMakeFiles/opencv_python3.dir/build.make:278: recipe for target 'modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o' Failed make[2]: *** [modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o] Error 1 CMakeFiles/Makefile2:18929: recipe for target 'modules/python3/CMakeFiles/opencv_python3.dir/all' Failed make[1]: *** [modules/python3/CMakeFiles/opencv_python3.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....
解决方法
我解决了这个问题.问题是python3_INCLUDE_DIR设置为〜/ anaconda3 / include而Anaconda的Python.h实际上位于〜/ anaconda3 / include / python3.5m内.设置python3_INCLUDE_DIR = anaconda3 / include / python3.5m /修复此问题,因为它现在看到Python.h
但是,这导致了另一个问题,其中某些.h文件如hdf5.h和H5public.h对OpenCV不再可见,因为它们位于主要的anaconda3 / include /目录中,而不是在子文件夹中.
解决方法是将include /目录中的所有.h文件复制到include / python3.5m目录中(将两者的内容复制到另一个目录中并将其设置为路径也可以工作)以便所有.h文件位于编译器可见的同一文件夹中. OpenCV现在正在构建！
