I am trying to build the latest rust compiler for the esp32 from GitHub - esp-rs/rust: Rust for the xtensa architecture. Built in targets for the ESP32 and ESP8266 using
python3 src/bootstrap/configure.py --experimental-targets=Xtensa --release-channel=nightly --enable-extended --tools=clippy,cargo,rustfmt,rust-analyzer-proc-macro-srv,src --dist-compression-formats='xz' --enable-lld
and python x.py dist --stage 2
It fails while compiling some windows_version_resource.rc for llvm (Building LLVM for x86_64-pc-windows-msvc) with the following message:

I am not sure what that means, manually running this (i.e. skipping the first half of the command)

works fine and produces the .res file.
