I have built a custom toolchain with a fairly standard config.toml
. Its diff from the example config is this:
> diff config.toml.example config.toml
152c152
< #build-stage = 1
---
> build-stage = 2
186c186
< #target = ["x86_64-unknown-linux-gnu"]
---
> target = ["x86_64-apple-darwin", "x86_64-apple-ios-macabi"]
253c253
< #extended = false
---
> extended = true
258a259
> tools = ["cargo", "rls", "clippy", "rustfmt", "analysis", "src"]
392c393
< #debug-logging = rust.debug-assertions (boolean)
---
> debug-logging = true
I have built the toolchain with ./x.py build
and it seems to have built everything I need.
~/code/rust/build/x86_64-apple-darwin > ls stage2/bin
rustc rustdoc
~/code/rust/build/x86_64-apple-darwin > ls stage2-tools-bin/
cargo cargo-credential-1password cargo-credential-macos-keychain clippy-driver rls rustfmt
I've linked this toolchain with ~/code/rust > rustup toolchain link myrust build/x86_64-apple-darwin/stage2
, set it in my other project with rustup override set myrust
, and tried to build it with cargo build --target x86_64-apple-ios-macabi
It gets farther than my previous attempts, but I get the following error while the build script gets run (trying to process gRPC proto files):
> cargo build --target x86_64-apple-ios-macabi

--- stderr
error: 'rustfmt' is not installed for the toolchain 'myrust'

How do I make rustfmt
visible as part of the toolchain?
