Bindgen relies on rustfmt. With the codebase I'm using rustfmt-nightly works, but the stable version segfaults. Known issue but that's why I've stuck with rustfmt-nightly.
I happen to be in the same physical location as the maintainers of both. This should be re-opened. I’ll chat with them. But first... I’m also confused. The component is the rustfmt-nightly codebase. You’re still seeing problems with the component?
I'm using bindgen to generate bindings for radare2. But I'm also using TryFrom, so I'm not likely to move off of the nightly toolchain any time soon.
Before I ended up going down the TryFrom rabbit hole I ran into two issues with bindgen:
1.) Bindgen segfaults with the ancient LLVM on OSX 10.9. Issue #1006. Solution: use LLVM >= 5 binaries from the LLVM site.
2.) Stable (deprecated) rustfmt causes bindgen to segfault. Solution: cargo install -f rustfmt-nightly. It could be as simple as "stable rustfmt requires --force to run because it's been deprecated", but more helpful error messages would be a great thing here.
So on the mac, something's going on and even with LIBCLANG_PATH set I'm still getting a segfault in some clang stuff. On the BSD box, rustfmt-nightly allows everything to work. Using `cargo install --force rustfmt` will provoke bindgen into reporting an internal error:
I get the same results if I call the bindgen executable or have build.rs call the bindgen API. I've stuck with having build.rs call the bindgen executable because if I use the bindgen API, compilation is SLOW.
