'TranslationUnit::parse failed' on aarch64-apple-ios since Bindgen 0.31 (original) (raw)

On my way trying to bump bindgen in my project from 0.26.3 to 0.32.1, found out that bindgen isn't working anymore from version 0.31 on the aarch64-apple-ios target, but is still working on other iOS and MacOS targets. I use Bindgen from a build.rs, which gets compiled for each target my project supports and fails on aarch64-apple-ios. Using the command line bindgen gives me the same result.

My setup:

My header:

typedef struct _foo_context foo_context; foo_context* foo_new(char* bar);

Bindgen Invocation:

$  RUST_BACKTRACE=1 bindgen --no-layout-tests --dump-preprocessed-input test.h -- --target=aarch64-apple-ios

Actual Results:

error: unknown target triple 'unknown-apple-macosx10.4.0', please use -triple or -arch

Found out a mention that "arm64" instead of "aarch64" could be passed to clang, which apparently works:

$ RUST_BACKTRACE=1 bindgen --no-layout-tests --dump-preprocessed-input test.h -- --target=arm64-apple-ios

Gives me

/* automatically generated by rust-bindgen */

#[repr(C)]
#[derive(Debug, Copy, Clone)]
pub struct _foo_context {
    _unused: [u8; 0],
}
pub type foo_context = _foo_context;
extern "C" {
 # [ link_name = "\u{1}_foo_new" ]
    pub fn foo_new(bar: *mut ::std::os::raw::c_char) -> *mut foo_context;
}

And it also works like before on all the other architectures I use:

aarch64-linux-android
armv7-apple-ios
armv7-linux-androideabi
armv7s-apple-ios
i386-apple-ios
i686-linux-android
x86_64-apple-darwin
x86_64-apple-ios
x86_64-linux-android

Thanks !
