Can you attach rustup show output? And please do so as text rather than screenshots. Also in case you ever ran rustup override set to set a specific version, do rustup override unset to remove it.

How do you compile it exactly? Because if you just do cargo build it will not use Rust version that you provided, but rather one defined in rust-toolchain.toml, which code compiles with just fine. It is not guaranteed that code will compile with older/newer versions of the compiler because we use n…

git clone https://github.com/subspace/subspace.git && cd subspace && git checkout gemini-3g-2023-dec-01 export RUSTFLAGS="-C target-cpu=native -C opt-level=3" && export CFLAGS="-march=native" && export CXXFLSGS="$CFLAGS" rustup update cargo build --profile production --bin subspace-farmer --bin subs…

Looks a bit random. I don’t think you need to specify optimization level (it is like that for production already) or C/C++ flags (not sure why you have them there). Also native is not always the most performant, but will not hurt generally. Even if you don’t specify any of those environment variable…

I always install Rust using curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh command. Looks a bit random. My friends suggested it to me… :man_shrugging:

Is rust-toolchain.toml present after you clone the repo? Something is clearly off, but from what you wrote I don’t see what it is.

Okay, can you run rustc --version in the project directory to see which compiler version it picked up?

Hm, that is not what it should be. For some reason it doesn’t select correct version. What does which rustc say?
