Build failure: setting llvm.experimental_targets is incompatible with download-ci-llvm #166

Closed mbuesch closed 1 year ago

With today's git default branch (4651851b1bb6f0d44543f0ec2c8d26e308aaadcf) I get the following build failure:

   ...
   Compiling fd-lock v3.0.8
   Compiling globset v0.4.8
   Compiling ignore v0.4.18
   Compiling toml v0.5.9
    Finished dev [unoptimized] target(s) in 1m 35s
thread 'main' panicked at 'setting llvm.experimental_targets is incompatible with download-ci-llvm.', config.rs:1207:17
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

My build commands are:

./configure --experimental-targets=Xtensa
./x.py build --stage 2

You probably want to add --release-channel=nightly to your configure step, the default when building from source is dev which will try and download llvm artifacts.

Just incase you weren't aware, we have prebuilt toolchains for most operating systems available here: https://github.com/esp-rs/rust-build.

Thanks. This fixed the build.
