WINCE6.0动态加载驱动问题

[andylao62]

出现如下错误

以下是我的GPIO.def
LIBRARY GPIO

EXPORTS
GPI_Init
GPI_Deinit
GPI_Open
GPI_Close
GPI_Read
GPI_Write
GPI_Seek
GPI_IOControl
GPI_PowerDown
GPI_PowerUp
说明WINCE6.0，我在DRIVER下建立的是一个动态WCE Dymanic-Link Library 驱动文件，然后单独编译，而D:\WINCE600\platform\LPC32XX\lib\ARMV4I\debug\GPIO.lib下没有 GPIO.lib这个文件，是不是还要设置那呢？

没人帮我吗。。。

从错误看，好像是没有相关函数的实现。
建议贴出sources文件和驱动代码，以便分析。

没有必要开这么多帖子吧~
我已经在其他帖子里回了。

大家帮忙看看有什么问题

MSDN上的解释为：Error LNK1120 gives you a count (number) of unresolved externals for this link. The conditions that cause unresolved externals are described with error LNK2001, which precedes this error message (once for each unresolved external).

今天是周末，周一上班再分析一下。哈哈
