我第一次尝试使用异常，但即使这是一个非常简单的示例，我也无法编译它，我查看了几个示例并尝试以多种不同的方式对其进行编码，但我什至不确定问题到底出在哪里，因为当我引入 catch/try/throw 时，我得到了名称处理，这是我的代码，希望它真的很愚蠢:)

#include "Surface.h"
#include "SDL_Image.h"

using namespace std;

SDL_Surface* surface::Load(string fileName){

   SDL_Surface* loadedSurface = IMG_Load(fileName.c_str());
   if(loadedSurface == 0) throw 0;

   //Convert surface to same format as display
   loadedSurface = SDL_DisplayFormatAlpha(loadedSurface);

   return loadedSurface;
}

#include "GameState.h"
#include "Surface.h"

#include<iostream>

using namespace std;

GameState::GameState(string fileName){

   try{
      stateWallpaper_ = surface::Load(fileName);
   }
   catch(int& e){
      cerr << "Could not load " << fileName << endl;
   }
}

提前感谢您的帮助！

编辑：对不起，我忘了发布错误信息：它是

从您的错误消息来看，问题与异常无关，而是与您的链接有关。您正在使用 SDL 标头但未链接到 SDL 库，请使用正确的-L选项。
