Windows 8使用Mingw在cmd中编译c ++ [英] Windows 8 Compiling c++ in cmd using Mingw

问题描述

我试图从命令行编译c ++程序，但我不能。我尝试了这里列出的所有步骤和说明

我安装了Mingw，但是在安装的最后一步，我解决了如何更改环境路径。在环境变量上根本没有PATH部分，当我尝试添加它，甚至编辑系统变量中的一个时，编译不起作用（当我在命令提示符下键入g ++时没有任何东西）。

我已经在线搜索解决方案，但我还没有找到任何东西。

编辑：重新安装mingw32解决了无法编译c ++的问题。

在cmd中的属性中的高级设置下的PATH变量中添加; C：\mingw \bin在cmd中固定编译，由@Chrono Kitsune

解决方案

1. 按 Win + R 类型

     sysdm.cpl，3 
     

   li>
   

2. 点击环境变量按钮。


3. 有两个部分：用户变量（顶部）和系统变量


4. 如果您没有 PATH 变量，请点击新建按钮，对变量名称键入 PATH 。否则，只需双击现有的 PATH 变量。


5. 现在将以下内容添加到变量值的末尾：

    ; C：\mingw\bin 
     

   其中 C：\mingw\bin 是包含 g ++。exe


6. 打开一个新的命令提示符，然后单击<确定>按钮。尝试执行

     g ++。exe -xc -E nul 
      
    





如果您仍然遇到错误，请尝试注销

I'm trying to compile c++ programs from the commandline but I can't. I tried all the steps and instructions listed here

I got Mingw installed but I get stuck in the last step of the installation that explains how to change environment paths. There simply isn't PATH part of it on the Environment variables, and when I try to do add it or even edit the one in System variables compiling doesn't work (nothing comes up when I type g++ in command prompt).

I've searched online for solutions but I haven't been able to find anything.

EDIT: reinstalling mingw32 resolved the issue of not being able to compile c++ at all.

Adding ;C:\mingw\bin in the PATH variable under Advanced Settings in Properties in My Computer fixed compiling in cmd, as answered by @Chrono Kitsune

解决方案

1. Press Win+R to open the Run dialog and type

   sysdm.cpl ,3
   

2. Click the "Environment Variables" button.
3. There are two sections: "User Variables" (top) and "System Variables" (bottom). You want to look at the top section.
4. If you don't have a PATH variable, click the "New" button and type PATH for the variable name. Otherwise, just double-click the existing PATH variable.

5. Now add the following to the end of the variable's value:

   ;C:\mingw\bin
   

   where C:\mingw\bin is the folder containing g++.exe.

6. Click OK on each dialog box to close it.

7. Open a new command prompt and try to execute

   g++.exe -xc -E nul
   

   If you still get an error, try logging off and logging back on.
