我正在尝试编译我的第一个 SDL 程序，但它无法编译。顺便说一句，我猜这不应该是关于设置库，因为我认为我正确安装了库。
这是我的命令：
g++ main.cpp -o main -I/Library/Frameworks/SDL2.framework/Headers -framework SDL2
这是我的代码：
#include <iostream>
#include <SDL.h>
int main(int argc, char **argv){
if (SDL_Init(SDL_INIT_EVERYTHING) != 0){
std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
return 1;
}
SDL_Quit();
return 0;
}
这是错误消息：
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我究竟做错了什么？感谢帮助 ：）
最后，这个命令起作用了：
g++ main.cpp -o main -I/Library/Frameworks/SDL2.framework/Headers -F/Library/Frameworks -framework SDL2
