Input C/C++ Header

typedef struct _IMAGE_TLS_DIRECTORY64 {
    ULONGLONG StartAddressOfRawData;
    ULONGLONG EndAddressOfRawData;
    ULONGLONG AddressOfIndex;         // PDWORD

Bindgen Invocation

    // Configure and generate bindings.
    let bindings = bindgen::builder()
        .header("../inc/libnet.h")
        //.clang_arg("-x").clang_arg("c++")
        .generate()
        .expect("Couldn't write bindings!");

    let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());

    // Write the generated bindings to an output file.
    bindings
        .write_to_file(out_path.join("bindings.rs"))
        .expect("Couldn't write bindings!");

or

$ bindgen input.h --whatever --flags

Actual Results

error[E0588]: packed type cannot transitively contain a `#[repr(align)]` type

#[repr(C, packed(4))]
#[derive(Copy, Clone)]
pub struct _IMAGE_TLS_DIRECTORY64 {
    pub StartAddressOfRawData: ULONGLONG,
    pub EndAddressOfRawData: ULONGLONG,
    pub AddressOfIndex: ULONGLONG,
    pub AddressOfCallBacks: ULONGLONG,
    pub SizeOfZeroFill: DWORD,
    pub __bindgen_anon_1: _IMAGE_TLS_DIRECTORY64__bindgen_ty_1,
}

and/or

// Insert the (incorrect/buggy) generated bindings here

and/or

Insert compilation errors generated when compiling the bindings with rustc here
