ios安装python的步骤,cmake编译iOS/android/mac的opencv库

编译环境

操作系统:Mac OS X 10.15.4 (19E266)

XCode :Version 11.4 (11E146)

cmake :cmake version 3.10.2

python:3.7.4_1

准备工作

1、下载源码

// 下载opencv_master源码

git clone https://github.com/opencv/opencv.git opencv_master

git checkout -b my-4.3.0 4.3.0

// 下载opencv_contrib源码

git clone https://github.com/opencv/opencv_contrib.git opencv_contrib

git checkout -b my-4.3.0 4.3.0

2、安装指定cmake版本和python版本

更改脚本

由于脚本是基于python2写的,为了兼容python3,这里需要更改脚本,否则提示

"ERROR: cannot use a string pattern on a bytes-like object"

1、将脚本platforms/ios/build_framework.py中的代码改成如下:

更改前

ret = check_output(["xcodebuild", "-version"])

更改后

encoding = 'utf-8'

ret = check_output(["xcodebuild", "-version"]).decode(encoding)

编译命令

python3 platforms/osx/build_framework.py --contrib=../opencv_contrib ../output/macosx

等待数分钟,默认将生成动态库
