我想第一次使用异常 但即使它是一个相当简单的示例我只是不能得到它编译,我看过 在几个例子,并试图对其进行编码在 许多,许多不同的方式 但我仍然甚至不能确定究竟在何处 的问题是,因为我有名字修饰 当我介绍捕捉/ TRY /扔反正 这里是我的代码希望它是东西 真的很蠢:)当我尝试使用异常时获取名称mangling [CodeBlocks,C++]
#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;
}
}
在此先感谢您的帮助!
编辑:对不起,我忘了发布错误信息:这是

你得到什么错误? –
什么名字?你会*在绑定中遇到绑定一个临时对象'int&'的问题。我会用'const int&',或者简单的'int'。 –
@BoPersson有趣的是,我的G ++版本(4.6)用'int&'获得'throw 0'。 –
