I'm trying to use bindgen on VSTGUI's vstgui.h file. However, upon executing bindgen, I'm spammed with the following line before bindgen panics seconds later:
C:\Program Files (x86)\Windows Kits\10\include\10.0.16299.0\ucrt\corecrt_wstdio.h:222:17: error: unknown type name 'FILE', err: true
There should be a way to fix this, otherwise Bindgen wouldn't be as widely used as it is. Any help would be appreciated. I already tried --opaque-type, but to no avail.
Looks like you need to include stdio.h before you can include vstgui.h
to do so your wrapper.h should look similar to this
// stdio.h contains `FILE`
#include <stdio.h>
// i have no idea if this is the right include patch adjust as needed
#include <vstgui.h>
Alternative if you call bindgen like this
bindgen::builder()
.header_contents("_stdio.h", "#include<stdio.h>\n")
...
Getting the same error for a different library (RtAudio). Adding #include <stdio.h> to wrapper.h doesn't work, I get whole host of nasty errors:

Problem is due to the library's reliance on exceptions. Fixed it by using an available C API.
