Hey,
Maybe I am just missing something blatantly obvious here, but trying to build rust support in -next fails for me. I am using ClangBuiltLinux clang version 15.0.0 5b0788fef86ed7008a11f6ee19b9d86d42b6fcfa and LLD 15.0.0. Is it just expected that building -next with rust support is not a good idea? My defconfig is the default RISC-V one plus: CONFIG_RUST=y CONFIG_SAMPLES=y CONFIG_SAMPLES_RUST=y CONFIG_SAMPLE_RUST_MINIMAL=y
Thanks, Conor.
