Description
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:
- MacOS 10.13.2 with Apple LLVM 9.0.0
- Rust 1.23.0
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 !
