sdl库
简介
SDL(Simple DirectMedia Layer)是一个跨平台的多媒体库,可以用来处理音频、视频、输入设备、网络和图形等。它提供了一组简单的API,可以让开发者轻松地创建跨平台的游戏和多媒体应用程序。
SDL最初是为了编写游戏而创建的,但现在也广泛用于其他类型的应用程序。它支持多个平台,包括Windows、Mac OS X、Linux、iOS和Android等。
以下是SDL库的一些主要功能:
- 窗口管理:SDL提供了一组API,可以用来创建和管理窗口,以及处理窗口事件。
- 图形渲染:SDL提供了一组API,可以用来处理图形渲染,如绘制图形、文本和图像等。
- 输入设备:SDL支持多种输入设备,如键盘、鼠标、手柄和触摸屏等。
- 音频和视频:SDL提供了一组API,可以用来处理音频和视频,如播放音频文件、录制音频、播放视频等。
- 网络:SDL提供了一组API,可以用来处理网络通信,如创建和管理网络连接等。
Simple DirectMedia Layer (SDL) is a cross-platform multimedia library that can be used to process audio, video, input devices, networks, and graphics. It provides a simple set of apis that allow developers to easily create cross-platform gaming and multimedia applications.
SDL was originally created to write games, but is now widely used for other types of applications as well. It supports multiple platforms, including Windows, Mac OS X, Linux, iOS and Android.
Here are some of the main features of the SDL library:
Window Management: SDL provides a set of apis for creating and managing Windows, as well as handling window events.
Graphics rendering: SDL provides a set of apis that can be used to handle graphics rendering such as drawing graphics, text, and images.
Input devices: The SDL supports multiple input devices, such as keyboards, mice, joypads, and touch screens.
Audio and Video: SDL provides a set of apis that can be used to process audio and video, such as playing audio files, recording audio, playing video, etc.
Network: The SDL provides a set of apis for handling network communications, such as creating and managing network connections.
验证SDL2是否已成功安装
#include <SDL.h> int main(int argc, char* argv[]) { SDL_Init(SDL_INIT_VIDEO); SDL_Window* window = SDL_CreateWindow("SDL Example", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN); SDL_Surface* surface = SDL_GetWindowSurface(window); SDL_Surface* image = SDL_LoadBMP("image.bmp"); SDL_BlitSurface(image, NULL, surface, NULL); SDL_UpdateWindowSurface(window); SDL_Delay(5000); SDL_FreeSurface(image); SDL_DestroyWindow(window); SDL_Quit(); return 0; }
配置安装

build-essential是一个Ubuntu/Debian操作系统上的软件包,它包含了一些必要的编译工具和库,用于编译和安装软件包。下面是一些关于build-essential的信息:
build-essential包含的工具和库包括:gcc、g++、make、libc-dev、dpkg-dev等。
build-essential是一个元包,它依赖于一些其他的包,这些包包含了实际的编译工具和库。
build-essential通常被用于编译和安装从源代码构建的软件包,这些软件包通常提供了源代码和一个Makefile文件。
安装build-essential可以通过命令sudo apt-get install build-essential实现。
build-essential是一个非常常用的软件包,几乎所有需要编译的软件包都需要依赖它。
sudo apt update && sudo apt upgrade #更新 sudo apt install build-essential # sdl2开发库及其附带的库 sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev
test(使用vscode进行测试)
sudo apt install code # kali自带包 其他操作系统只能去官网下载vscode #创建一个新的文件夹,用于存放SDL项目 mkdir ~/sdl_project cd ~/sdl_project touch main.cpp #配置VSCode以使用正确的编译器和链接器。在sdl_project文件夹中,创建一个名为.vscode的文件夹,并在其中创建两个文件:c_cpp_properties.json和tasks.json mkdir .vscode touch .vscode/c_cpp_properties.json touch .vscode/tasks.json
#include <SDL2/SDL.h> int main(int argc, char* argv[]) { SDL_Init(SDL_INIT_VIDEO); SDL_Window* window = SDL_CreateWindow("SDL2 Window", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN); SDL_Delay(3000); SDL_DestroyWindow(window); SDL_Quit(); return 0; }
