最近在把SDL封装起来 好为以后写代码轻松些.

出现了这个错误.英文翻译大概是:不可以把字符串常量变成char*指针.

char *title= "test";

SDLWindow* window = new SDLWindow(title,400,500,400,500,SDL_WINDOW_SHOWN);

 

修改后：

char title[] = "test";

SDLWindow* window = new SDLWindow(title,400,500,400,500,SDL_WINDOW_SHOWN);

 

就可以运行了.

stackoverflow大牛回答:

If a function takes a char const *, it guarantees that it only reads whatever data the pointer points to. However, if it takes a non-const pointer, like char *, it might write to it.

As it is not legal to write to a string literal, the compiler will issue a warning.

The best solution is to change the function to accept char const * rather than char *.

 

最好的方法是修改函数参数 把char * 改成 char const * . 我还晕着...
