The variable or function cann't link the declaration.
The variable "MessageIdentifier" cann't link to its declaration, but its declaration is at the top of the picture below.
For another example:
The function "Det_ReportError" cann't link to its declaration, but its declaration is at another file which belong to this project.
When I click this item of "Open Declaration" there is no any response.So how do I do to resolve this problem?
