Can't compile Rust project in conda environment in Docker - docker

Question

I'm trying to build the following sightglass benchmarking suite/ Dockerfile:
FROM ubuntu:22.04

RUN echo 'APT::Install-Recommends "0";' >> /etc/apt/apt.conf.d/00-docker

RUN ./yes/envs/rustenv/bin/cargo build --release --target wasm32-wasi
RUN cp target/wasm32-wasi/release/bls-381-wasm-benchmark.wasm /benchmark.wasm
The build process always aborts on the compile step with the following error:
error[E0463]: can't find crate for `core`
|
= note: the `wasm32-wasi` target may not be installed
= help: consider downloading the target with `rustup target add wasm32-wasi`
error[E0463]: can't find crate for `compiler_builtins`
My full setup can be found here: https://github.com/achimcc/arkworks-wasmtime-benchmarks/tree/main/benchmarks/bls12-381

Answer 1

It seems you are compiling something whose target is wasm32-wasi.
Rust can compile source codes for different "targets", but only few of them was enabled by default.
To install the wasm32-wasi target, you can run this command:
rustup target add wasm32-wasi
