derived class from wxWidgets can not compile in Linux

I derived class from wxGrid and wxTaskBarIcon, the project is normal in
windows compiling with VC6, but in SuSE Linux Enterprise Server 9, I got the following errors:
undefined reference to 'vtable for CMyGrid'

the compile errors point to the constructor and destructor function in the source file (.cpp).

urgent, thanks!

Why are you deriving from both wxGrid and wxTaskbarIcon? Do not use multiple inheritence when dealing with wxWidgets objects, for any reason what so ever.

CMyGrid and CMyTaskBarIcon

SnakeChomp's comment still applies. You cannot inherit from two controls expecting to get both functionality in one class.

Maybe this might help

I think multiple inheritence would cause compiling errors. Maybe you should try checking and removong things like "#pragma interface"
