incorrect value for codegen option split-debuginfo

[omac777]

Problem

The error output was:

error: incorrect value `...` for codegen option `split-debuginfo` - one of supported split-debuginfo modes (`off`, `packed`, or `unpacked`) was expected

error: could not compile `libc` due to previous error
warning: build failed, waiting for other jobs to finish...
error: could not compile `proc-macro2` due to previous error
error: could not compile `autocfg` due to previous error
error: could not compile `unicode-ident` due to previous error
error: could not compile `quote` due to previous error
error: could not compile `cfg-if` due to previous error
error: could not compile `serde_derive` due to previous error
error: could not compile `syn` due to previous error

Steps

1. did a rustup update

nightly-x86_64-unknown-linux-gnu updated - rustc 1.69.0-nightly (001a77fac 2023-01-30) (from rustc 1.68.0-nightly (61a415be5 2023-01-12))

2. set the env variable as requested in https://blog.rust-lang.org/inside-rust/2023/01/30/cargo-sparse-protocol.html

CARGO_REGISTRIES_CRATES_IO_PROTOCOL=sparse

3. then proceeded to build an app

cargo clean
cargo update
RUSTFLAGS=-Awarnings cargo +nightly build --release

Possible Solution(s)

No response

Notes

Version

rustc 1.69.0-nightly (001a77fac 2023-01-30)

I tried to revert to a previous nightly and the above error remains.

You may want to check your Cargo.toml or .cargo/config.toml if there is any profile.split-debuginfo being set.

I guess someone copy-pasting the split-debuginfo = "..." from the sample configuration here.

[omac777]

I checked everywhere in all my Cargo.toml files in my workspace and there were no occurrences there.

There is no file .cargo/config.toml

I checked the .cargo/ looking for Cargo.toml files containing "..." and found some occurrences but nothing with split-debuginfo being used.

My only suggestion is that the rust compiler could help out here and indicate what crate/file/line the occurrence was found as the origin of this error reported.

I re-ran my build like so:

cargo +nightly-x86_64-unknown-linux-gnu build --release --verbose --verbose --verbose
Here's the verbose error output, but I'm finding it hard to read and understand.

Have you checked the config discovery chain?

You could also use the unstable cargo config command to help you find where is the origin of a config value.

cargo +nightly config get -Z unstable-options --show-origin

[weihanglo]

Just saw you use -Zshare-generics=y and other unstable features. Maybe you have installed fleet before? I got an impression that they had a bad configuration back in the day. dimensionhq/fleet#55

[omac777]

I was searching for occurrences in all Cargo.toml files within my workspace, but I never searched for occurrences in all config.toml files within my workspace and your command caught that. That helped a great deal. thank you.

 $ cargo +nightly config get -Z unstable-options --show-origin

I decided to go with split-debuginfo = 'packed'

[weihanglo]

Glad you figure it out. Going to close this.

[omac777]

Usually this workspace the build time takes 2-3 minutes. In this case, it actually completed it in 36 seconds. That's a startling improvement just by setting the CARGO_REGISTRIES_CRATES_IO_PROTOCOL=sparse environment variable!!!

[omac777]

Yes please close this issue. You're a super-hero @weihanglo :)
Thanks again.
