This is affecting Arch Linux's 5.8 kernel now so I've looked around a bit.
I didn't find anything to tell modpost to skip our .rust.o. (Unless you meant the mod->skip
field which was removed in torvalds/linux@0b19d54cae11bd5b9e208f52e42d88ad33a3b1d9 but wasn't exposed anyways.)
Fortunately it seems to suffice to just create an empty file with the correct name.
%.rust.o: target/x86_64-linux-kernel/debug/lib%.a
$(LD) -r -o $@ --whole-archive $<
+ touch $(dir $@)/.$(notdir $@).cmd
Along with some changes from your filter-out-plugins branch I'm able to build hello-world
again on Arch.
I see this warning:
Looking around a bit, I see torvalds/linux@70f30cfe5b892fcb7f98e7df72ed6ccfe3225628, which I'm now worried about:
I think we need to either generate the .cmd file or explicitly tell modinfo to skip our .o file. (I assume the skip option exists because closed-source modules with precompiled .o files are a thing.)
I think this is generated as an
-MD
or thereabouts of input C files, and we could almost certainly do that easily for bindings.c. I'm less sure if we can do that for bindgen but presumably it's doable somehow with libclang....
