Visual Studio 命令提示 工具原理解析

观察“Visual Studio 2005 命令提示”的属性，发现运行“Visual Studio 2005 命令提示”即运行

%comspec% /k ""d:/Microsoft Visual Studio 8/VC/vcvarsall.bat"" x86

其中 comspec即%SystemRoot%/system32/cmd.exe，故以上命令行即“以x86为参数，运行vcvarsall.bat批处理文件”

查看vcvarsall.bat文件的源代码


@echo off


if "%1" == "" goto x86


if not "%2" == "" goto usage




if /i %1 == x86 goto x86


if /i %1 == amd64 goto amd64


if /i %1 == x64 goto amd64


if /i %1 == ia64 goto ia64


if /i %1 == x86_amd64 goto x86_amd64


if /i %1 == x86_ia64 goto x86_ia64


goto usage




:x86


if not exist "%~dp0binvcvars32.bat" goto missing


call "%~dp0binvcvars32.bat"


goto :eof




:amd64


if not exist "%~dp0binamd64vcvarsamd64.bat" goto missing


call "%~dp0binamd64vcvarsamd64.bat"


goto :eof




:ia64


if not exist "%~dp0binia64vcvarsia64.bat" goto missing


call "%~dp0binia64vcvarsia64.bat"


goto :eof




:x86_amd64


if not exist "%~dp0bin†_amd64vcvarsx86_amd64.bat" goto missing


call "%~dp0bin†_amd64vcvarsx86_amd64.bat"


goto :eof




:x86_ia64


if not exist "%~dp0bin†_ia64vcvarsx86_ia64.bat" goto missing


call "%~dp0bin†_ia64vcvarsx86_ia64.bat"


goto :eof




:usage


echo Error in script usage. The correct usage is:


echo %0 [option]


echo where [option] is: x86 ^| ia64 ^| amd64 ^| x86_amd64 ^| x86_ia64


echo:


echo For example:


echo %0 x86_ia64


goto :eof




:missing


echo The specified configuration type is missing. The tools for the


echo configuration might not be installed.


goto :eof

不难发现，实际运行的代码是

:x86

if not exist "%~dp0bin/vcvars32.bat" goto missing

call "%~dp0bin/vcvars32.bat"

goto :eof

即运行当前目录下的bin目录下的vcvars32.bat文件，这个文件的内容非常简单，如下：

"%VS80COMNTOOLS%vsvars32.bat"

其中VS80COMNTOOLS为系统变量，在我的机器上取值d:/Microsoft Visual Studio 8/Common7/Tools/

故找到该目录，并查看其下的vsvars32.bat，代码如下


@SET VSINSTALLDIR=d:Microsoft Visual Studio 8


@SET VCINSTALLDIR=d:Microsoft Visual Studio 8VC


@SET FrameworkDir=C:WINDOWSMicrosoft.NETFramework


@SET FrameworkVersion=v2.0.50727


@SET FrameworkSDKDir=d:Microsoft Visual Studio 8SDKv2.0


@if "%VSINSTALLDIR%"=="" goto error_no_VSINSTALLDIR


@if "%VCINSTALLDIR%"=="" goto error_no_VCINSTALLDIR




@echo Setting environment for using Microsoft Visual Studio 2005 x86 tools.




@rem


@rem Root of Visual Studio IDE installed files.


@rem


@set DevEnvDir=d:Microsoft Visual Studio 8Common7IDE




@set PATH=d:Microsoft Visual Studio 8Common7IDE;d:Microsoft Visual Studio 8VCBIN;d:Microsoft Visual Studio 8Common7Tools;d:Microsoft Visual Studio 8Common7Toolsin;d:Microsoft Visual Studio 8VCPlatformSDKin;d:Microsoft Visual Studio 8SDKv2.0in;C:WINDOWSMicrosoft.NETFrameworkv2.0.50727;d:Microsoft Visual Studio 8VCVCPackages;%PATH%


@set INCLUDE=d:Microsoft Visual Studio 8VCATLMFCINCLUDE;d:Microsoft Visual Studio 8VCINCLUDE;d:Microsoft Visual Studio 8VCPlatformSDKinclude;d:Microsoft Visual Studio 8SDKv2.0include;%INCLUDE%


@set LIB=d:Microsoft Visual Studio 8VCATLMFCLIB;d:Microsoft Visual Studio 8VCLIB;d:Microsoft Visual Studio 8VCPlatformSDKlib;d:Microsoft Visual Studio 8SDKv2.0lib;%LIB%


@set LIBPATH=C:WINDOWSMicrosoft.NETFrameworkv2.0.50727;d:Microsoft Visual Studio 8VCATLMFCLIB




@goto end




:error_no_VSINSTALLDIR


@echo ERROR: VSINSTALLDIR variable is not set.


@goto end




:error_no_VCINSTALLDIR


@echo ERROR: VCINSTALLDIR variable is not set.


@goto end




:end

不能发现此文件的作用即为完成与VS2005相关的一些系统变量的设置，如：

VSINSTALLDIR——VS2005的安装路径；

VCINSTALLDIR——VC的安装路径；

FrameworkDir——Framework2.0的安装路径；

等等。

这样，如果我们需要自己写一个批处理文件，完成一些VS2005相关的设置，调用VS2005提供的一些工具（如gacutil，该工具在D:/Microsoft Visual Studio 8/SDK/v2.0/Bin目录下，该目录没有被Path系统变量引用，故该命令无法直接在cmd中运行），就可以在批处理文件的开头先调用vsvars32.bat，然后在调用VS2005的相关工具。代码举例如下：

call "%VS80COMNTOOLS%vsvars32.bat"

gacutil /i YejunWorkshop.IDUControlLibrary.Design.dll

该批处理文件直接运行即可将YejunWorkshop.IDUControlLibrary.Design.dll程序集添加到GAC中。
