i686-14.2.0-release-mcf-dwarf-ucrt-rt_v12-rev1.7z
i686-14.2.0-release-posix-dwarf-msvcrt-rt_v12-rev1.7z
i686-14.2.0-release-posix-dwarf-ucrt-rt_v12-rev1.7z
i686-14.2.0-release-win32-dwarf-msvcrt-rt_v12-rev1.7z
i686-14.2.0-release-win32-dwarf-ucrt-rt_v12-rev1.7z
x86_64-14.2.0-release-mcf-seh-ucrt-rt_v12-rev1.7z
x86_64-14.2.0-release-posix-seh-msvcrt-rt_v12-rev1.7z
x86_64-14.2.0-release-posix-seh-ucrt-rt_v12-rev1.7z
x86_64-14.2.0-release-win32-seh-msvcrt-rt_v12-rev1.7z
x86_64-14.2.0-release-win32-seh-ucrt-rt_v12-rev1.7z

这里有很多版本：

• x86_64和i686是64位和32位的区别，seh和dwarf分别专用于此
• posix和win32是线程模型的区别，posix跨平台，win32性能好
• ucrt和msvcrt是运行时库的区别，ucrt只有win10+支持

现在都是win10以上的系统了，肯定选x86_64-14.2.0-release-posix-seh-ucrt-rt_v12-rev1.7z

下载解压后，将bin文件夹添加到环境变量，其中包括了gcc和make

配置VSCODE

安装CMake Tools插件

在工作区创建两个源文件

main.c

#include 
extern void test_cmake();
int main(int argc, char const *argv[])
{
    test_cmake();
    printf("Hello, World!\n");
    return 0;
}

test_cmake.c

#include "stdio.h"
void test_cmake()
{
    printf("Hello from test_cmake\n");
}

在工作区创建CMakeLists.txt，输入如下内容后，左下角就会生成调试和运行按钮

cmake_minimum_required(VERSION 3.10)

# Set the project name
project(TEST_C)

# Add all .c files in the current directory
file(GLOB SOURCES "*.c")

# Add an executable
add_executable(main ${SOURCES})
