vs2010 command prompt 运行时停在Setting environment for using Microsoft Visual Studio 2010 x86 tools.

在win7上安装vs2012后运行，command line tool时，cmd窗口停在了Setting environment for using Microsoft Visual Studio 2010 x86 tools界面

解决办法

修改c:\Program Files\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat文件，在第一行echo之后添加，根据自己安装的路径修改相应变量

@SET VSINSTALLDIR=c:\Program Files\Microsoft Visual Studio 10.0\

@SET VCINSTALLDIR=c:\Program Files\Microsoft Visual Studio 10.0\VC\

@SET FrameworkDir32=c:\Windows\Microsoft.NET\Framework\

@SET WindowsSdkDir=C:\Program Files\Microsoft SDKs\Windows\v7.0A\

@SET FrameworkVersion32=v4.0.30319

@SET Framework35Version=v3.5

注释如下三句

::@call :GetVSCommonToolsDir

::@if "%VS100COMNTOOLS%"=="" goto error_no_VS100COMNTOOLSDIR

::@call "%VS100COMNTOOLS%VCVarsQueryRegistry.bat" 32bit No64bit

注意要在上面论坛的路径后加\，否则cl用不了。
