In the middle of writing the program and testing it, there were a bunch of syntax errors that came from xUtility files.
opens the xutility file, which defines many constructs and function templates. Find the source of the error is not found, because it is similar to the lack of; “And so on. So back before writing the code, and finally found the problem: in the global defines a short function, then the short function and a function template name repetition, combined with the incoming parameters when calling type does not conform to the global defines the type of function, to the template, but does not define the type of template function, hence lead to errors.
correction method:
1. Change function name, error parameter type will report the correct position
2. Use scope to avoid ambiguity caused by improper parameter types
