you usually get those linker errors when the linker can't find bits of your code. It could be that you have declared some functions in a class or header file but have not implemented them. Or, you have forgotten to import a library or something like that.

Also possible that you have [tt]#include[/tt]d a header file, but not added the corresponding implementation file to the project, so it isn't being compiled and isn't part of the [tt].obj[/tt]?

Thanks for qednick and Jim03.
your comments is right. Some functions are declared, there. But, not defined.
