rustc stage 2 and rsutup toolchain link fails with the path with white space

[dupeiran001]

although it's not recommended to use a path with white space

I tried to compile my rustc stage 2, following the guide.

my environment is macOS 13.4

I have my dev dir in iCloud, which absolute path is : /Users/xxx/Library/Mobile Documents/com~apple~CloudDocs/Develop, has a white space in it.

when trying to link to the rustup toolchain with command

rustup toolchain link stage1 build/host/stage1

it fails with message:

error: not a file: 'build/host/stage1/bin/rustc'

these all fail for linking stage0 or stage2

but it works well if I copy the whole dir to a non-spacing dir

it's all the same to rustc compilation with command:

./x.py build --stage 2

with error message:

 Compiling rustc_smir v0.0.0 (/Users/dpr/Library/Mobile Documents/com~apple~CloudDocs/Develop/Rust/rust/compiler/rustc_smir)
The following warnings were emitted during compilation:

warning: clang: error: no such file or directory: 'Documents/com~apple~CloudDocs/Develop/Rust/rust/build/aarch64-apple-darwin/ci-llvm/include'

error: failed to run custom build command for `rustc_llvm v0.0.0 (/Users/dpr/Library/Mobile Documents/com~apple~CloudDocs/Develop/Rust/rust/compiler/rustc_llvm)`

Caused by:
  process didn't exit successfully: `/Users/dpr/Library/Mobile Documents/com~apple~CloudDocs/Develop/Rust/rust/build/aarch64-apple-darwin/stage0-rustc/release/build/rustc_llvm-e9be9ad0694a7cad/build-script-build` (exit status: 1)

// with some other std out
......

the line staring with warning obviously prints only the latter parts of the dir after the space.

I suppose maybe it fails to recognize the space in the path and separate it into two?

compiling rustc in a directory with a space doesn't work because of llvm-config not supporting it. There's an issue somewhere I think

yeah this is a duplicate of #56650
