直接解压即可。设置环境变量![20190416145402829.png][]

1.2 win+r 输入CMD打开命令行输入g++ --version如图则成功：

2.Cmake安装

官网地址[https://cmake.org/download/ ][https_cmake.org_download_]

下载最新的.msi文件直接下载。傻瓜式安装记得添加环境变量。选择 **"Add CMake to the system PATH for all users"**

2.2 安装完成打开cmd 输入cmake,如下图，则成功。

3.编写实例。如下图创建一个文件夹，下面由build,main.cpp,CMakeLists.txt三个文件。如下图：

3.2 CMakeLists.txt内容如下：

cmake_minimum_required(VERSION 3.4)
    
    PROJECT(hello_world)
    
    INCLUDE_DIRECTORIES(
        ${PROJECT_SOURCE_DIR}
    )
    set(SRC
        ${PROJECT_SOURCE_DIR}/main.cpp
    )
    ADD_EXECUTABLE(hello ${SRC})

3.3 main.cpp内容如下：

#include<iostream>
    using namespace std;
    
    int main(int argc,char const *argv[])
    {
        cout<<"hello"<<endl;
        return 0;
    }

4.启动cmake工具，生成makefile,文件选择如图：上面步骤3所在的文件夹

4.2点击configure按钮，选择MinGW Makefiles,如图：

4.3然后点击Generate按钮生成makefile文件。

4.4cmd命令行进入makefile文件所在目录即build目录，如图：

4.5 输入 make  即可。如图

得到。exe文件如图：

4.6继续在该cmd命令行下输入 hello.exe即可得到 输出。

5.补充，在4.5中 的make命令需要找到mingw安装目录下mingw32-make.exe拷贝一份并重命名为make.exe，如图：
