If multiple target files contain definitions with the same name as the global symbol, the duplicate definition error will occur when these target files are linked.For example, if we define a global integer variable in both the target file a and the

If the target file strongly references the symbols of the external target file, but cannot be correctly resolved when it is linked to an executable file (look at p_51 for a strange name), the linker will report an error, this is for strong reference.
