Hello,

I am trying to generate the C structs for Rust using the bindgen. Below is my build.rs file content

use std::env;
use std::path::PathBuf;

fn main() 
{
    let illd_include = r"<path>\Infineon_Libraries\iLLD\TC37A";

    let bindings = bindgen::Builder::default()
        .header("wrapper.h")
        .use_core()
        .ctypes_prefix("core::ffi")
        .allowlist_type("IfxDma_Dma_Channel")
        .allowlist_type("IfxDma_Dma_ChannelConfig")
        .clang_arg(format!("-I{}", illd_include))
        .generate()
        .expect("Unable to generate bindings");

    let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
    bindings
        .write_to_file(out_path.join("bindings.rs"))
        .expect("Couldn't write bindings!");
}

Wrapper.h

#include "IfxDma_Dma.h"

I am encountering the following error:

error: failed to run custom build command for rust_code v0.1.0 (<path>\source_code\DMA_Data_Transfer\rust_code)

Caused by:

I am unable to fix the issue. It would be of great help to know the issue and fix it.

Thanks
