use winapi crate instead of generating bindings to windows.h

[ghost]

Hi, I couln't find any way to do this in docs or the book, I am generating bindings to vulkan but when I add a definition to make it include windows support It includes windows.h, build takes a long time and it crashes with no output. I want to ignore the windows.h include somehow and use winapi crate instead. Is there a way to this?

The way to do something like that is to blacklist the windows types and adding something like use winapi::* using raw_line.

Bindgen shouldn't be crashing though (and it's somewhat suprising it does since I'm pretty sure on Firefox bindgen ends up including windows.h without issues).

I don't have a windows machine, but would there be any chance for you to try to dump the contents make bindgen crash for you and upload them here?

A reduced test-case would be extra-awesome, but just a reproducible crash / hang is awesome on its own.

hi, bindgen doesn't crash but I get this error when compiling the generated bindings: error[E0588]: packed type cannot transitively contain a [repr(align)] type. the generated rust file is 1 line so the error was too long, thats why I couldn't see anything. so I think this is duplıcate of #1538.

Yeah, with_rustfmt and such helps a lot to diagnose errors :)

Why was this issue closed? IMO there should be a switch like --use-winapi

The original author came to believe the underlying issue is a duplicate of another open issue.

@bugproof, if you have a need, maybe you should open a new issue to describe what use you would have for --use-winapi.

I have the same problem. Was there ever a solution?

Reproducible example is literally a header file that includes windows.h. In my case this is what is leading to it:

#include <windows.h>
#include "ViGEm/Client.h"

//
// Link against SetupAPI
//
#pragma comment(lib, "setupapi.lib")

Ideally there would be some kind of windows.h shim I could include that will automatically get converted to use the winapi crate when bindgen sees it. Short of that I don't see how this is going to work as the library I'm linking with uses windows.h types all over the place

followup: Looks like if you blacklist the following types build will succeed with all of windows.h:

        .blacklist_type("_IMAGE_TLS_DIRECTORY64")
        .blacklist_type("IMAGE_TLS_DIRECTORY64")
        .blacklist_type("PIMAGE_TLS_DIRECTORY64")
        .blacklist_type("IMAGE_TLS_DIRECTORY")
        .blacklist_type("PIMAGE_TLS_DIRECTORY")

Hey, can somebody here answer the original question a bit better?

How am I supposed to "blacklist the windows types"? I tried blocklisting windows.h and that doesn't work. I was suggested to use regex to filter out all the functions, but Microsoft uses hungarian notation so that doesn't work.
