Thanks a lot for trying it out and for the feedback! :-) The supported architectures are in Documentation/rust/arch-support.rst, so we should link to that. x86 32-bit and other architectures should eventually work -- we need to put some time into them and setting up a few things. For the moment we focused on x86_64 and arm64. > Then I got failure because libclang (?) was not installed. I installed > it. But I guess that should be mentioned in docs as dependency. Yeah, this is mentioned on the bindgen section in quick-start.rst, I will try to improve make it more clear, perhaps I'll a section for libclang itself. > With CONFIG_RUST unset, kernel builds for me.

I get errors: Typically it is due to a kernel option that enables some GCC flag that libclang does not know about -- I have a hack in place to make it work, but requires manual maintenance. Can you please attach your kernel config? Meanwhile, please try building with Clang or LLVM instead, the GCC builds are very, very experimental. I'll make it even more explicit in the quick-start.
