正在帮别人调试一个WDM驱动程序，编译环境为Win2K Free Build Environment ,编译指令为build -cZ, 编译时提示一下信息：

出现上述问题后检查原文件，经过艰苦的战斗，定位于一条语句上，
FieldBitMask = NTSCBitField[ Idx - 1 ];

NTSCBitField定义为static const DWORD NTSCBitField[NTSC_MAX_FRAME_RATE]；
FieldBitMask 为long。
Idx为局部变量，类型为unsigned int。
只要将上述语句注释，就可以通过。但这条语句我怎么也发现不了错误。要是错的话，编译就不能通过，问题是编译通过了，但链接没有通过。

非常郁闷，期待高手给予解决！！！！！！

看上去好像是需要找不到某个.lib文件

[newblood]

估计不是该句的问题, 你是不是走入了误区.
仔细看错误提示, 无法找到该符号表.
.lib 的缺少也是有可能.
