build/bootstrap/debug/rustc -vV throws error with env

[vinay110974]

Hi,

We are implementing Oe-Selftest for rust in Yocto Framework.
The test runs complete rust testsuite for all folders.
However, we are facing an issue while printing the verbose details in many testcases.
It is hindering the test process and unable to run many folders.

$oe-selftest/build-st/tmp/work/core2-64-poky-linux/
rust-testsuite/1.60.0-r0/rustc-1.60.0-src/build/bootstrap/debug/rustc -vV

thread 'main' panicked at 'RUSTC_SYSROOT was not set', src/bootstrap/bin/rustc.rs:50:48
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Same issue is observed with rust native build also.
It was noted that the issue has been addressed earlier as:- #39888

Can you please let us know whether the issue still persists in rust or we missing anything
while building rust that addresses the issue?

Regards,
Vinay

Typically you should never run the bootstrap wrappers directly. You should run the rustc from the appropriate stage directory. For example, build/x86_64-unknown-linux-gnu/stage1/bin/rustc -vV

Hi @ehuss,

Thanks for quick reply.
build/x86_64-unknown-linux-gnu/stage1/bin/rustc -vV gives the expected output.

rustc 1.60.0-dev
binary: rustc
commit-hash: unknown
commit-date: unknown
host: x86_64-unknown-linux-gnu
release: 1.60.0-dev
LLVM version: 14.0.0

Will check with rust test-suite and update.

Going to close this since using the fake rustc shim directly isn't supported.
