问题描述

在我的电脑上，我有Windows 7 x86。我安装MinGW，我写了路径，但是当我在cmd.exe和写g ++ -v它说：

 g ++ 不被识别为内部或外部命令。 
  

但是当我写make -v命令时，我需要这个学校，我在Eclipse，我甚至安装最新的java（我看到它必须安装）。

解决方案

您必须修改环境变量。请执行以下操作：

• 从桌面右键单击计算机并单击属性。


• 计算机属性窗口中，单击更改设置。


• 在打开的系统属性窗口中，单击高级选项卡。


• 单击环境变量按钮。


• 最后，在环境变量窗口中（如下所示），突出显示系统变量部分中的路径变量，然后单击编辑按钮。使用您希望计算机访问的路径添加或修改路径行。

On my computer I have Windows 7 x86. I installed MinGW, I wrote the path but when I go in cmd.exe and write g++ -v it says:

"g++" is not recognized as an internal or external command.

But when I write the make -v command it recognizes it. I need this for school, I work in Eclipse, I even installed the latest java(I saw it must be installed).

解决方案

You have to modify environment variables. Do the following:

• From the desktop, right-click Computer and click Properties.
• From the Computer Properties window, click Change Settings
• In the System Properties window which opens up, click on the Advanced tab.
• In the Advanced section, click the Environment Variables button.

• Finally, in the Environment Variables window (as shown below), highlight the Path variable in the Systems Variable section and click the Edit button. Add or modify the path lines with the paths you wish the computer to access. Each different directory is separated with a semicolon as shown below.

  C:\Program Files;C:\Winnt;C:\Winnt\System32
