Description
I get the ICE below when I compile this fragment of code:
static FUNCS: [ErlNifFunc; 1] = [
ErlNifFunc{ name: "native_add\0",
arity: 2,
function: native_add,
flags: 0,
}
];
#[no_mangle]
pub extern "C" fn nif_init() -> *const ErlNifEntry {
static ENTRY: ErlNifEntry = ErlNifEntry{
major : NIF_MAJOR_VERSION,
minor : NIF_MINOR_VERSION,
name : "rustnif\0",
num_of_funcs : 1,
funcs : &FUNCS, <-------- ICE here
load : None,
reload : None,
upgrade : None,
unload : None,
vm_variant : "beam.vanilla\0",
options: 0,
};
&ENTRY
}The above structs are defined here: https://github.com/goertzenator/rustertest/blob/995b9f2cf484cd753e2818adb95ec8ad5370456c/src/lib.rs
The above fragment is part of https://github.com/goertzenator/rustertest/tree/995b9f2cf484cd753e2818adb95ec8ad5370456c
That crate depends on https://github.com/goertzenator/ruster/tree/e1bf38e30f1bcf2caf17080ed57b7cdc70ff182f
And that crate requires erlang-17.4 to be installed.
