VScode+SDL2配置教程

前天我想找一个图形库写个小工具，想找个小巧一点的图形库，于是就找到了ege(easy graphics engine)，花了点时间配置到了vscode上，顺便写了个文章，这是教程地址：https://blog.csdn.net/qq272508839/article/details/104287255

今天想起一个比较知名的图形库叫SDL，很早之前就听过，于是我就下载了一个打算试试，是在MinGW环境下的，具体配置MinGW的方法我就不说了，很简单。

先到官网：http://www.libsdl.org/下载两个东西，如下图：

对应自己的平台下载，我是win10 64位。

下载完是这俩东西：

509kb那个是用来编译完之后放到exe同级目录的，下面那个tar是需要自己安装的部分。

解压tar.gz，里面有这么几个文件夹：

标出的这俩文件夹是需要放到MinGW安装目录里的，不是俩都要复制，对应自己的MinGW版本复制一个就好，我是64位MinGW，我就要x86_64开头的那个了。

打开x86_64开头的文件夹，里面有几个文件夹（bin、include、lib、share）：

把这几个文件夹全部选中，复制到MinGW安装目录里面\x86_64-w64-mingw32目录中，要是32位的MinGW呢就是MinGW安装目录里面\i686-w64-mingw32，复制完了之后会发现下图中的目录里多出一个SDL2，这就说明安装完成了：

然后就是配置vscode了，新建一个工程文件夹，在工程根目录新建.vscode目录（vscode前一个点别忘了），在.vscode目录里新建3个json文件：tasks.json、launch.json、c_cpp_properties.json，然后把509kb那个压缩包解压出一个文件叫SDL2.dll，把这个dll复制到exe同级目录，在根目录下建一个main.c，如下图：

然后就是复制代码粘贴到对应的文件里了，直接上代码。

tasks.json

{"version": "2.0.0","tasks": [{"type": "shell","label": "g++.exe build active file",//注意改成自己的MinGW目录"command": "C:\\mingw64\\bin\\g++.exe","args": ["-g","${file}","-o","${fileDirname}\\${fileBasenameNoExtension}.exe","-lmingw32","-lSDL2main","-lSDL2","-mwindows"],"options": {//注意改成自己的MinGW目录"cwd": "C:\\mingw64\\bin"},"problemMatcher": ["$gcc"],"group": {"kind": "build","isDefault": true}}]
}

launch.json

{"version": "0.2.0","configurations": [{"name": "g++.exe build and debug active file","type": "cppdbg","request": "launch","program": "${fileDirname}\\${fileBasenameNoExtension}.exe","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb",//注意改成自己的MinGW目录"miDebuggerPath": "C:\\mingw64\\bin\\gdb.exe","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}],"preLaunchTask": "g++.exe build active file"}]
}

c_cpp_properties.json

{"configurations": [{"name": "Win32","includePath": ["${workspaceFolder}/**",//注意改成自己的MinGW目录"C:\\mingw64\\x86_64-w64-mingw32\\include\\**"],"defines": ["_DEBUG","UNICODE","_UNICODE"],"compilerPath": "C:\\mingw64\\bin\\gcc.exe","cStandard": "c11","cppStandard": "c++17","intelliSenseMode": "gcc-x64"}],"version": 4
}

main.c

#include <SDL2/SDL.h>SDL_Window *window = NULL;
SDL_Surface *surface = NULL;//main函数中的参数不能省略，不然会报错
int main(int args, char *argv[])
{SDL_Init(SDL_INIT_VIDEO);window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_SHOWN);if (!window)return -1;surface = SDL_GetWindowSurface(window);if (!surface)return -2;SDL_Rect rec;rec.x = 700;rec.y = 10,rec.w = 20;rec.h = 20;while (1){SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 180, 10, 140));rec.x += 6;rec.y += 2;rec.x = rec.x > 800 ? 0 : rec.x;rec.y = rec.y > 600 ? 0 : rec.y;SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 10, 200, 120));SDL_UpdateWindowSurface(window);SDL_Delay((1.0 / 60) * 1000);}SDL_FreeSurface(surface);SDL_DestroyWindow(window);SDL_Quit();return 0;
}

大功告成，按Ctrl+Shift+B编译，得到main.exe，双击运行：
