我已经尝试重新编码一段时间了,所以我想我应该从一些简单的 SDL 开始,现在,没有文件 i/o,编译得很好,但是当我输入 stdio 代码时,它开始抛出错误。我不确定这一点,我没有看到代码本身有任何问题,但是,就像我说的,我也可能是一个新手,并且认为我应该来这里找一个有更多经验的人这种东西就看看吧。
我想我的问题可以归结为:“为什么它不能在 Microsoft 的 Visual C++ 2008 Express 下编译?”
我已在代码片段的底部附加了错误日志。预先感谢您的帮助。
#include "SDL/SDL.h"
#include "stdio.h"
int main(int argc, char *argv[])
{
FILE *stderr;
FILE *stdout;
stderr = fopen("stderr", "wb");
stdout = fopen("stdout", "wb");
SDL_Init(SDL_INIT_EVERYTHING);
fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n");
SDL_Quit();
fprintf(stderr, "SDL QUIT.\n");
fclose(stderr);
fclose(stdout);
return 0;
}
报告的实际错误:

main.cpp(6) : error C2528: '__iob_func' : pointer to reference is illegal

最佳答案
#include "SDL/SDL.h"
#include "stdio.h"
int main(int argc, char *argv[])
{
FILE *stderr; //Invalid names. These are already defined by stdio.h.
FILE *stdout; //You can't use them (portably anyway).
stderr = fopen("stderr", "wb"); //I'm assuming you actually want files
stdout = fopen("stdout", "wb"); //called "stderror" and "stdout".
SDL_Init(SDL_INIT_EVERYTHING);
fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n");
SDL_Quit();
fprintf(stderr, "SDL QUIT.\n");
fclose(stderr);
fclose(stdout);
return 0;
}
尝试将名称 stderr 和 stdout 更改为其他名称。我怀疑编译器正在提示,因为这些已经在 C 库的其他地方定义了。
