toolchain 'nightly-x86_64-pc-windows-gnu' does not have the binary rust-gdb.exe

[norru]

This is the affected toolchain:

nightly-x86_64-pc-windows-gnu unchanged - rustc 1.30.0-nightly (ae7fe84e8 2018-09-26)

Can this be worked around effectively?

I think the problem is just that dist.rs does not install this script on Windows? See https://github.com/rust-lang/rust/blob/master/src/bootstrap/dist.rs#L591-L614

Not sure. This bug relates to the windows-gnu toolchain rather than windows-msvc.

I think it's an issue with rustup proxies:

$ rust-gdb
error: 'rust-gdb.exe' is not installed for the toolchain 'nightly-x86_64-pc-windows-gnu'

Triage: closing since rust-gdb was not missing. This might be a rustup bug, but that should be reported to rustup in that case.
