當(dāng)使用WDK（我這里版本W(wǎng)DK 7600.16385.1）命令行編譯一個(gè)驅(qū)動(dòng)程序時(shí)，進(jìn)入到當(dāng)前驅(qū)動(dòng)所在的文件夾目錄下，一般都有一個(gè)Sources文件，內(nèi)容一般是：

TARGETNAME=UsbKbd
TARGETTYPE=DRIVER
DRIVERTYPE=WDM
TARGETPATH=OBJ
#TARGETLIBS=C:98DDKLIBI386FREEUsbd.Lib
TARGETLIBS=$(DDK_LIB_PATH)Usbd.Lib

INCLUDES=$(BASEDIR)inc;

SOURCES=	Init.cpp?
			Dispatch.cpp?
			Pnp.cpp?
			DeviceIo.cpp?
			Usb.cpp?
			DebugPrint.c?
#			UsbKbd.rc

NTTARGETFILES=PostBuildSteps

例如上面的Sources例子里（是編譯UsbKbd驅(qū)動(dòng)），“#”是注釋符，“DDK_LIB_PATH”等環(huán)境變量定義在什么地方呢？

開啟一個(gè)WDK命令行編譯環(huán)境，執(zhí)行下面操作：

C:WinDDK7600.16385.1>set?>c:1.txt

上面操作的意思是，將當(dāng)前命令行cmd下所有的環(huán)境變量輸出到c:1.txt內(nèi)，打開該文件，如下：

在這里，就能找到“DDK_LIB_PATH”等環(huán)境變量定義值了。（如上我開啟的是WinXP的Check版本的編譯環(huán)境）

舉一反三：

① ?啟動(dòng)一個(gè)默認(rèn)的CMD命令行環(huán)境，執(zhí)行“set >c:1.txt”后，再開啟VS2012的命令行提示編譯環(huán)境，執(zhí)行“set >c:2.txt”，用文件比較工具比較兩個(gè)文件的不同。這兩個(gè)文件的不同，就是VS2012命令行編譯環(huán)境做的特殊設(shè)置。

② 用同樣的方式，可以查看WinCE5.0、Tornado2.2命令行編譯設(shè)置的不同；

② 用同樣的方式，查看Visual Studio之間做的設(shè)置環(huán)境變量區(qū)別：VC++6.0的設(shè)置環(huán)境變量位置一般在“C:Program Files (x86)Microsoft Visual StudioVC98Bin”下，為“VCVARS32.BAT”；VS2005，VS2008，VS2012分別在菜單下有命令行編譯提示工具設(shè)置；
