MSYS不刷新输出 [英] msys not flushing output

问题描述

我在Windows上将mingw与msys和mintty一起使用.我有一个问题，即msys和mintty直到命令执行完毕才以某种方式不刷新输出.这意味着我不能真正运行任何交互式程序.

I'm using mingw with msys and mintty on windows. I have a problem that msys and mintty are somehow not flushing output until a command is finished. This means I can't really run any interactive programs.

例如，如果我在C中:

printf("Test\n");

直到程序终止，输出才会出现.但是，如果我有:

the output won't appear until the program has terminated. However, if I have:

printf("Test\n"); fflush(stdout);

然后将立即显示输出.如果我使用没有薄荷味的msys或Windows控制台，则一切正常.

then the output appears immediately. If I use msys without mintty or the windows console, then everything works normally.

所以我的问题是，msys和mintty怎么了?

So my question, what's going on with msys and mintty?

推荐答案

在许多情况下 msys 使用 rxvt shell时，这可能是一个问题.在遇到此问题的情况下，我要求msys将本机Windows Shell用于其控制台.例如:

This can be an issue when msys uses the rxvt shell under a number of scenarios. In cases where I see this problem, I ask msys to use the native Windows shell for its console. For example:

C:\MinGW\msys\1.0\msys.bat --no-rxvt

我认为现代MSYS安装默认使用本机外壳，因为MSYS开发人员似乎更喜欢它.我的本机外壳还有其他问题，这些问题促使我使用 rxvt 外壳，因此我很少遇到此问题.

I thought that modern MSYS installations default to using the native shell as MSYS developers seem to prefer it. I have other issues with the native shell that drive me to use the rxvt shell, so I do infrequently run into this issue.

C:\MinGW\msys\1.0\msys.bat --rxvt

我发现 rxvt 外壳程序通常可以正常运行，但某些应用程序是作为控制台"实用程序构建的，这些应用程序可以从命令行运行.

I find that the rxvt shell usually works fine except for certain applications that are built as "console" utilities meant to run from a command-line.
