问题描述
所以我试图为 arm 设备交叉编译 OpenCV，在运行 cmake 时，我注意到在输出中没有找到 PythonLibs.我的系统中同时安装了 Python2 和 Python3 库.
so Im trying to cross-compile OpenCV for an arm device and while running cmake, I noticed in the output that the PythonLibs were not found. I have both Python2 and Python3 libs installed in my system.
这是输出
-- 找到 PythonInterp:/usr/bin/python2.7(找到合适的版本2.7.12"，最低要求是2.7")
-- 找不到 PythonLibs(缺少:PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)(需要精确的版本2.7.12")
-- 找到 PythonInterp:/usr/bin/python3(找到合适的版本3.5.2"，最低要求是3.4")
-- Found PythonInterp: /usr/bin/python3 (found suitable version "3.5.2", minimum required is "3.4")
-- 找不到 PythonLibs(缺少:PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)(需要确切的版本3.5.2")
在输出结束时，我也注意到了这一点
Towards the end of the output, I also noticed this
Python 2:
解释器:/usr/bin/python2.7 (ver 2.7.12)
Python 3:
解释器:/usr/bin/python3 (ver 3.5.2)
Python(用于构建):/usr/bin/python2.7
Python (for build): /usr/bin/python2.7
由此我可以得出结论，未构建 Python 绑定.如果有人对我如何解决这个问题有任何建议，我很乐意倾听.
From this I could conclude that the Python bindings were not built. If someone had any suggestion on how I can fix this, I would be happy to listen.
推荐答案
你正在尝试编译一些简单的请求 DEV 包的东西，你只有 Python 解释器包，在 Raspberry PI 中你必须有 python-dev 和 python3-dev 为例，如果你使用的是树莓派尝试运行:
You are trying to compile something that is simple requesting the DEV packages, you have only the Python interpreters packages, in Raspberry PI you must have python-dev and python3-dev for example, if you are using Raspberry PI try to run:
sudo apt-get install -y python-dev python3-dev
然后你会通过这一步，如果有其他错误再发新帖.
Then you will pass this step, if there come another errors make new posts.
