Description of bug

Compiling the current main tip (commit 87b1b4728e29f68c6b2bafde7f3d0f4c8af9b302) of the node template results in this error:

   Compiling node-template-runtime v4.0.0-dev (/home/werk/Code/substrate-node-template/runtime)
error: failed to run custom build command for `node-template-runtime v4.0.0-dev (/home/werk/Code/substrate-node-template/runtime)`

Caused by:
  process didn't exit successfully: `/home/werk/Code/substrate-node-template/target/debug/build/node-template-runtime-5ecf88b7b75beaf9/build-script-build` (exit status: 1)
  --- stderr
  Cannot compile the WASM runtime: no compatible Rust compiler found!
  Install at least Rust 1.68.0 or a recent nightly version.

• I am able to successfully compile commit tagged as polkadot-v0.9.40.
• I am using rust 1.69 with wasm backend and nighly options enabled.

Steps to reproduce

substrate-node-template> git checkout 87b1b4728e29f68c6b2bafde7f3d0f4c8af9b302
substrate-node-template> cargo c

Some similar reports seem to be made here: #12791

[deepink-mas]

In case this failure is related to #13580:

• $ rustc --version
  rustc 1.69.0-nightly (84c898d65 2023-04-16) (gentoo)
• $ cargo --version
  cargo 1.69.0-nightly

[deepink-mas]

Version::extract("cargo 1.69.0-nightly").unwrap(); // panicked at 'called Option::unwrap() on a None value'

[deepink-mas]

Since the checking code accepts any nightly a workaround is to: export RUSTC_BOOTSTRAP=1

I got the same error, but the root cause may be different.

  The following warnings were emitted during compilation:

  warning: error: unable to create target: 'No available targets are compatible with triple "wasm32-unknown-unknown"'
  warning: 1 error generated.

  error: failed to run custom build command for `secp256k1-sys v0.6.1`

warning: build failed, waiting for other jobs to finish...

I know the error. It only occurs on macOS with Xcode bundled LLVM, and the WASM target has C binding crates. Changing to the Homebrew LLVM will solve the problem. It's just annoying.

The problem introduced to node-template from #14452

@jasl yes this is not related and is caused by the pr you linked.
