Ida and efiutils

Is more visible and easy to follow code.
Like that

But aricart long time ago was last time online.

https://github.com/snarez/ida-efiutils

Can someone explain how to do that.
Or tell me what I do wrong.

-open module in IDA
-initial analyze is performed
-File > Load file > Parse C header file > select behemoth.c
-message compilation successful

-View > open subview > Local types
-on Local type window, select all > synchronize to IDB > Do you really want to copy selected local types to structure ... ,press yes

But for all of them message is "failed to add constant"

Thanks.
