psp-hello-world-example rust-lld: error: --strip-all and --emit-relocs may not be used together about rust-psp

Did you cargo build or cargo psp?

cargo psp

This is odd, the same toolchain version works on linux for me. Maybe the lld version is off, or perhaps you have conflicting rust-llds somehow. Can you run the following from the hello-world directory:

rustc --print sysroot

And then also, to check the rust-lld version:

cd ~/.rustup/toolchains/nightly-2021-12-05-x86_64-unknown-linux-gnu/lib
LD_LIBRARY_PATH=. ./rustlib/x86_64-unknown-linux-gnu/bin/rust-lld -flavor gnu -v

Today I tried to run cargo psp again, for some reason it wanted to recompile rust-psp. Then it seems every macro doesn't work...

Maybe my rustup toolchain is completely broken and I should reinstall everything?

[overdrivenpotato]

Could be. Try this in the hello-world directory:

cargo uninstall cargo-psp
rustup toolchain uninstall nightly
rustup toolchain install --profile default nightly
rustup override set nightly
rustup component add rust-src
cargo install cargo-psp
cargo clean
cargo psp

Are you trying to use std? That isn't ready/recommended at this time.

[overdrivenpotato]

Was this resolved on your end, or possibly by one of the new library versions? I'll keep the issue open if it's still causing trouble.

[overdrivenpotato]

I'm assuming this has been fixed with a toolchain update, as I cannot reproduce this. Feel free to re-open this issue if it is still causing problems.
