bindgen & LLVM 18 support for Rust

[yujack008]

I getting start with https://rust.binary.ninja/binaryninja/index.html#writing-a-plugin
My rustc version is rustc 1.77.0 (aedd173a2 2024-03-17)
My LIBCLANG_PATH is "E:\clang+llvm-18.1.5-x86_64-pc-windows-msvc\bin"
step:
1.cargo new --lib deobf
2.edit Cargo.toml

[lib]
crate-type = ["cdylib"]

[dependencies]
binaryninja = {git = "https://github.com/Vector35/binaryninja-api.git", branch = "dev"}

3.cargo build

then get so much error!

Are you using the build.rs from the guide?

i have build fine on llvm 17.0.6

I believe that this is a duplicate from Slack. User resolved this by downgrading to LLVM 17.0.6. Internally we're still on LLVM 16. No real idea about the effort required to fix this will be, but I'm hoping it's just some new flags we need to set (or something similar). I'll leave this open to track the status of bindgen/LLVM18 support.
