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.framework
,headers
,SDL.h
...

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>

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>
