Package: bindgen
X-Debbugs-Cc: [email protected], [email protected], [email protected]
Version: 0.66.1-7+b2
Severity: important
Tags: patch, fixed-upstream
Hi,
Current Sid's `bindgen` will run into a kernel build failure in the
future (in a few weeks, when the new tracepoints support gets merged):
$ bindgen --version --verbose
bindgen 0.66.1
Clang: Debian clang version 19.1.2 (2)
$ make LLVM=1 samples/rust/rust_print.o
...
error[E0425]: cannot find value `__tracepoint_rust_sample_loaded` in crate
`$crate::bindings`
--> samples/rust/rust_print.rs:87:5
...
The issue triggers with `bindgen` < 0.69.5 && `libclang` >= 19.1. Debian
Testing is fine (at least the `debian:testing` image), since `libclang`
is older there.
Upstream has a fix (released for 0.70.0 and backported to 0.69.5) at:
https://github.com/rust-lang/rust-bindgen/pull/2824
600f63895f73 ("Use clang_getFileLocation instead of
clang_getSpellingLocation")
35f0f9aafc9b ("Use clang_getFileLocation instead of
clang_getSpellingLocation")
It is a single line change which can be cleanly cherry-picked into
`bindgen` 0.66.1.
I confirmed the change would fix the issue (using `debian:sid` image): I
downloaded the Sid package sources (rust-bindgen and rust-bindgen-cli),
built the kernel to confirm the issue is there, then applied the single
line change to the sources, built the kernel again successfully.
Upgrading to `bindgen 0.70.x` should also fix the issue.
The consequence of not doing anything would be that kernel developers
using Debian would need to install a custom/newer `bindgen`, possibly
via `cargo`, instead of using their distribution package, which would be
inconvenient for them -- we are trying to keep the kernel buildable with
distributions' toolchains, e.g. see our instructions for Debian at:
https://docs.kernel.org/rust/quick-start.html#debian

Thanks!
Cheers,
Miguel
