sdl2/sdl.h 文件未找到

Question

当我尝试在 mac 上使用 vscode 和 clang++ 创建一个窗口时，我遇到了一个问题，其中安装了 sdl2（使用 home-brew）但 vscode 找不到它。这是我在终端中遇到的错误。

 *  Executing task: C/C++: clang build active file 

Starting build...
/usr/bin/clang -std=gnu++14 -std=c++17 -stdlib=libc++ -g 
/Users/jst_/Coding/VS.Code_C++/Main.CPP -o 
/Users/jst_/Coding/VS.Code_C++/Main
/Users/jst_/Coding/VS.Code_C++/Main.CPP:1:10: fatal error: 'SDL2/SDL.h' file not found
#include <SDL2/SDL.h>
         ^~~~~~~~~~~~
1 error generated.

Build finished with error(s).

 *  The terminal process failed to launch (exit code: -1). 
 *  Terminal will be reused by tasks, press any key to close it. 

The code for the window is


#include <SDL2/SDL.h>

int main() {
    SDL_Init(SDL_INIT_VIDEO);

    SDL_Window* window = SDL_CreateWindow("My Window", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN);
    if (!window) {
        // Handle window creation failure
        SDL_Quit();
        return 1;
    }

    SDL_Delay(3000); // Pause for 3 seconds

    SDL_DestroyWindow(window);
    SDL_Quit();
    return 0;
}

        }
    ],
    "version": 4
}

我多次尝试寻找不同的路径，最终找到了正确的路径，但没有什么区别，我仍然遇到相同的错误。

在使用 clang 编译的 Tasks.json 中的第一个任务中，您忘记添加 args 的路径，这就是您收到错误的原因，因为您使用 clang 进行编译，并且在该任务中包含路径（其中 SDL/sdl2 .h 位于）丢失。
