如何单步调试驱动程序

哪位大哥知道如何单步调试驱动程序,不然的靠打印调试信息太麻烦了

设断点啊，让驱动在目标机或者是仿真器上跑。

to wwei_wang：
经常看到你的留言，真是精彩。
我在平台下写的dll,在CPP文件中加上Extern \"C\"
再在需要导出的函数前面加上
__declspec(dllexport)
设置断点道是可以。

现在想问一个问题：
我如果想调试其它的驱动，如display驱动，把加入一个dll空项目中，根本编译不过去。（当然，用build命令还是可以的），那么如何设置断点呢？
只能用RETAILMSG等显示吗？

编译不过去，那可能是因为缺少所需的头文件和库文件吧。

多谢，可能是确实缺少库文件，可发现下面还有好的.S汇编Arm文件,加入到工程中(因为C程序调用汇编程序),发现无法编译,究竟该如何是好?
下面是source文件的内容:

（1）我没太明白啊：）））你是在pb中新创建一个空的dll，然后把已有的驱动文件代码加进去再编译，还是通过makefile和source文件进行编译？
（2）另外，你说无法编译，那么能否把出错信息贴上来？

to milesky:
     你好!你说的RetailMSG或者DebugMSG信息是显示在PB里面的Build窗口嘛?我怎么没有显示的哪?
     我的驱动源码中都加入了此类代码,但是在目标板运行的时候却没有看到这类信息的显示,可否给我说明白一点哪,先谢谢了 :)

sorry,milosky,写错了 ;)

也可以利用OEMWriteDebugString通过串口输出调试信息；

最近忙，没有上网，请帮忙看看：是链结的错误

老兄是你的某个库文件没有导入，看看是否缺少某个库文件导入就可以了。
