我正在尝试使用SDL。我在/Library/Frameworks中有一个名为SDL2.framework的文件夹。我想在我的项目中包含文件SDL.h。我该怎么做呢?我的代码如下:

// Example program:
// Using SDL2 to create an application window

#include <SDL.h>
#include <stdio.h>

int main(int argc, char* argv[]) {
    SDL_Window *window;                    // Declare a pointer
    SDL_Init(SDL_INIT_VIDEO);              // Initialize SDL2
    // Create an application window with the following settings:
    window = SDL_CreateWindow(
        "An SDL2 window",                  // window title
        SDL_WINDOWPOS_UNDEFINED,           // initial x position
        SDL_WINDOWPOS_UNDEFINED,           // initial y position
        640,                               // width, in pixels
        480,                               // height, in pixels
        SDL_WINDOW_OPENGL                  // flags - see below
    );
    // Check that the window was successfully made
    if (window == NULL) {
        // In the event that the window could not be made...
        printf("Could not create window: %s\n", SDL_GetError());
        return 1;
    }
    // The window is open: enter program loop (see SDL_PollEvent)
    SDL_Delay(3000);  // Pause execution for 3000 milliseconds, for example
    // Close and destroy the window
    SDL_DestroyWindow(window);
    // Clean up
    SDL_Quit();
    return 0;
}

我得到的错误是:

Aarons-MacBook-Air:SDL aaron$ g++ main.cpp
main.cpp:4:10: fatal error: 'SDL.h' file not found
#include <SDL.h>
          ^ 1 error generated.

如何正确包含SDL文件?它位于SDL2.frameworkheadersSDL.h ...

2 个答案:

答案 0 :(得分:15)

你会想要为此制作一个构建脚本,但重要的部分是:

-I/usr/local/include或您的标头安装位置。

我用家酿:

brew install sdl2

将库放在/usr/local/Cellar/

所以如果你需要指定lib路径,你还要添加:

-L/usr/local/lib -lSDL2

我还将您的包含行更改为#include <SDL2/SDL.h>

答案 1 :(得分:1)

您的标题文件位于Headers文件夹下,因此要正确包含此标题:

clang++ -std=c++11 -stdlib=libc++ -I/Library/Frameworks/SDL2.framework/Headers/

但我建议用homebrew安装:

brew install sdl2

Homebrew将在/ usr / local / lib和/ usr / local / include下安装SDL2 libSDL2.a文件,因此您只需要使用-L for library包含此库路径,并使用-I标志添加搜索/ usr / local / include dir:

clang++ -std=c++11 -stdlib=libc++ main.cpp -I/usr/local/include -L/usr/local/lib -lSDL2 -o programfile

并包括:

#include <SDL2/SDL.h>
