Comment 16 for bug 1993183

Hi all,

I would like to confirm that I can build the mainline kernel on jammy with the rust/bindgen packages in the proposed repository. However the kernel seems to have rust disabled due to incompatible configuration options (CONFIG_MODVERSIONS, CONFIG_DEBUG_INFO_BTF, and CONFIG_HAVE_GCC_PLUGINS).

If I patch debian.master/config/annotations (see attached) to disable those options, and enable RUST and the RUST sample code, then the build fails with:

***
