what is the error of Error 126: Inconsistent structure definition 'unnamed' in C?

Question

I am trying to link the my C code, and I got the following error message:

Error 126: Inconsistent structure definition 'unnamed'

there is no line number indicated which line has problems, and I do not have any structure of "unnamed", so I can not post the suspected code to here, have anyone experience this and how to fix it?
