cmake安装
-
官网下载地址Download | CMake

我这次选择的是免安装程序。Windows x64 ZIP，这样就不需要安装了，避免安装后生成一些临时文件，只需要添加一个环境变量就可以直接使用了。 官网下载地址特别慢，可以在这个地址下载Index of /files (cmake.org)，稍微快一些。
-
设置环境变量
把bin目录添加到path环境变量
环境变量 -
命令行测试
查看cmake版本号
C:\Users\jun>cmake --version
cmake version 3.22.1
CMake suite maintained and supported by Kitware (kitware.com/cmake).

mingw安装
- 官网下载地址MinGW-w64 - for 32 and 64 bit Windows - Browse Files at SourceForge.net
步骤1：打开files目录
!!!!!!!!!!!!!!!!不要直接点击上图的download那个红色按钮!!!!!!!!!!!!!!!!!!!!!!!!
网页滑到文件下面如下图：
步骤2：下载非安装版本，上图的第二个框框
普通windows系统电脑选择x86_64-win32-sjij -
下载后解压到本地任意目录，里面的文件目录如下图：
mingw目录结构 -
设置环境变量
把上图的bin目录添加到path环境变量
环境变量 -
打开命令行测试
测试gcc、g++命令，查看版本号
C:\Users\jun>gcc --version
gcc (x86_64-win32-sjlj-rev0, Built by MinGW-W64 project) 8.1.0

测试c语言编译

新建测试工程文件
- 新建一个文件夹test_c，目录结构如下：
-test_c-|
|---build
|---src-|
|---main.c
|---CMakeLists.txt
- CMakeLists.txt内容如下：
set(PROJECT CProject_main)
message("Making ${PROJECT} ...")
cmake_minimum_required(VERSION 3.16)
project(${PROJECT})
aux_source_directory(./src SRC_FILE)
add_executable(run ${SRC_FILE})
message("Make ${PROJECT} ok, please execute run")
- main.c内容如下：
#include <stdio.h>
int main()
{
printf("hello world ,this is a c program in win10\n");
return 0;
}
打开命令行
参考【CMake】Win10 + CMake + MinGW 简单使用_zhaotun123的博客-CSDN博客_cmake mingw
在build目录执行cmake命令
cmake .. -G "MinGW Makefiles"
命令解释：
- cmake： cmake执行命令，生成makefile文件
- ..：CMakeLists.txt路径
- -G：指定makefile类型
-
"MinGW Makefiles"：mingw的makefile类型
执行结果如下：
PS D:\Programs\projects\win_c\test_c> ls

在build目录下执行make命令
mingw32-make
命令行解释：
-
mingw32-make： mingw编译器的make命令，相当于Linux下的make
执行结果如下
PS D:\Programs\projects\win_c\test_c\build> mingw32-make

[100%] Linking C executable run.exe

PS D:\Programs\projects\win_c\test_c\build>
运行可执行程序
命令行运行run.exe结果如下
