SDL控制台输出在调试时工作，但在使用exe运行时不起作用 [英] SDL Console output works when debuging, but not when run with the exe

问题描述

我在写一个实验性网络程序，基本上是一个用于学习网络的测试程序。我使用SDL和SDL_net在Code :: Blocks与mingw，所以控制台输出被定向到stdout.txt。我搜索一下，发现你可以通过包括在SDL_Init（）后修复这个问题：

I am writing an experimental networking program, basically a test program for learning networking. I am using SDL and SDL_net in Code::Blocks with mingw, so the console output was being directed to stdout.txt. I searched around and found that you can fix this by including after SDL_Init():

freopen("CON", "w", stdout); //stops redirect of output
freopen("CON", "w", stderr); //and errors...

这个工作完美，但是只有当构建和运行程序IDE：当在IDE外部运行时（例如双击程序），程序运行正常，除了控制台输出（仍然为空白）。由于程序应该是一个控制台程序这是一个严重的问题...我不想总是运行程序在IDE中使用它。

This worked perfectly, but only when building and running the program in the IDE: when run outside of the IDE ( e.g. double clicking on the program) the program runs properly, with the exception of the console output, which is still blank. As the program is supposed to be a console program this is a severe problem... I don't want to have to always run the program in the IDE to use it.

任何解决方案都是apreciated，但我更喜欢这是一个改动的代码，虽然在夹捏一个批处理文件将做（我已经读了几个帖子，这是唯一的作品，但他们没有' t进入更多的细节，所以我不能复制它）。感谢。

Any solution is apreciated but I would prefer that it was an alteration to the code, although in a pinch a batch file will do (I've read a couple of posts where this is the only thing that works, but they didn't go into much detail, so I can't replicate it). Thanks.

推荐答案

您看过 SDL控制台常见问题？

他们提供了许多建议，包括：

They provide many suggestions, including:

首先尝试

freopen( "CON", "w", stdout );
freopen( "CON", "w", stderr );

如果无法使用（例如您的情况），请尝试

If it doesn't work (like in your case), try

#include <fstream>
#include <iostream>
using namespace std;
....
ofstream ctt("CON");
freopen( "CON", "w", stdout );
freopen( "CON", "w", stderr );
...
ctt.close();

或

FILE * ctt = fopen("CON", "w" );
freopen( "CON", "w", stdout );
freopen( "CON", "w", stderr );
...
ctt.close();

另一个选项是重新编译 SDLmain 库或者将 SDLmain 代码添加到您的项目中，并停止与库的链接。

Another option is to recompile the SDLmain library or add the SDLmain code to your project and stop linking against the library.
