Build failure with llvm 19

[blackcross86]

I tried this code:

  Compiling rustc_driver v0.0.0 (/root/rust-nightly/BUILD/rustc-nightly-src/compiler/rustc_driver)
error: linking with `cc` failed: exit status: 1

@blackcross86 can you please share:

• System information (OS, environment info, etc.)
• Your config.toml
• How you invoked bootstrap, i.e. what ./x invocation did you use, any additional flags?
• What commit your are trying to build from?

Thanks.

I find it difficult to answer about the commit
downloaded today
https://static.rust-lang.org/dist/rustc-nightly-src.tar.xz

But this is connected with the system llvm, an unclear error, what does it need?

[demqa]

same issue. compiling with llvm-17.0.6. using own version of llvm. I am using llvm-config in config.toml. compiling rust 1.77.2 with rust 1.76.0.

UPD: configured bootstrapping to use lld, and this issue had disappeared
