I defined a new type and changed the function signatures and local variables in the Pseudocode window so that they use this type. But IDA itself displays this type as unused. She did not see references to him.

If I look for xrefs in the pseudocode window, it sees. Problem types have a "copyof_TYPE_NUMBER" mark. That structure refer to itself in the list of local types.

What is the problem? How to fix it?

  • "xrefs" are for variables not for the data types. Your 1st image has the CHFileHeader structure definition whereas the 2nd image has the header variable of that structure type. – Biswapriyo Dec 11 '18 at 7:42
