windows下gcc编译opencv和boost

windows gcc编译opencv和boost gcc安装

官网下载gcc https://sourceforge.net/projects/mingw-w64/files/
安装版本无法下载文件，我使用的是x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z文件
解压软件到设定目录

将D:\mingw64\bin添加到系统环境变量中
打开cmd确认配置是否正确

C:\Users\pt>gcc --version
gcc (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0
Copyright (C) 2018 Free Software Foundation, Inc.

显示gcc版本后，表示gcc配置成功。

opencv4.5编译

下载opencv源码，采用cmake编译。启动cmake，设置opencv源码路径及编译后生成的代码路径

点击configure，选择MinGW，点击Finsh

本电脑关闭了

• OPENCV_GENERATE_SETUPVARS
• OPENCV_ENABLE_ATOMIC_LONG_LONG ##不关闭报错,找不到long文件
• 依次点击configure和generate.(过程确保没有错误日志)

打开cmd命令窗口,到build文件夹下,执行mingw32-make.exe install

编译完成后,在install目录下生成编译完成的文件.

boost 1.77编译

进入到解压目录下, 编译gcc版本b2

cd D:\ptwork\boost_1_77_0_gcc\boost_1_77_0\tools\build>
PS D:\ptwork\boost_1_77_0_gcc\boost_1_77_0\tools\build> .\bootstrap.bat gcc

已复制         1 个文件。

Building is done. To install, run:

    .\b2 --prefix=DIR install

将b2.exe文件拷贝到boost根目录(D:\ptwork\boost_1_77_0_gcc\boost_1_77_0)下.执行
.\b2.exe --toolset=gcc install --prefix=“d:\boost_gcc”,编译完成后会在d:\boost_gcc生成编译完成的文件.

PS D:\ptwork\boost_1_77_0_gcc\boost_1_77_0> .\b2.exe --toolset=gcc install --prefix="d:\boost_gcc"
