The following chain of repository dependencies lead to the missing definition

[QuentinPerez]

👋

Since the 0.15.0, I can not build anymore due to the following error, has something changed ?

rust_register_toolchains(
    edition = "2021",
    extra_target_triples = [
        "aarch64-apple-ios-sim",
        "aarch64-apple-ios",
        "aarch64-linux-android",
        "x86_64-unknown-linux-gnu",
    ],
    # rustup default nightly-2022-12-12
    include_rustc_srcs = True,
    iso_date = "2022-12-12",
    rustfmt_version = "nightly",
    version = "nightly",
)

...

The following chain of repository dependencies lead to the missing definition.
 - @crate_index
 - @rust_darwin_aarch64__aarch64-apple-darwin__stable_tools
This could either mean you have to add the '@rust_darwin_aarch64__aarch64-apple-darwin__stable_tools' repository with a statement like `http_archive` in your WORKSPACE file (note that transitive dependencies are not added automatically), or move an existing definition earlier in your WORKSPACE file.

[UebelAndre]

This can occur if you have custom toolchains defined. Is that the case?

[UebelAndre]

Oh, I'm sorry, I see the issue. Try replacing iso_date and version with

versions = [
    "nightly/2022-12-12",
    "1.66.0",
]

Either that or you can update your crates_repository definitions to force the {channel} parameter on rust_toolchain_rustc_template and rust_toolchain_cargo_template to explicitly be set to nightly. Sorry about the miscommunication there.

The latter is what likely what you want to do.

[QuentinPerez]

Thank you for the answers, no worries.

any

I got the same issue with versions = ["nightly/2022-12-12"], it goes further with versions = ["nightly/2022-12-12", "1.66.0"] and I had this one.

Error in fail: rustfmt_iso_date must be specified if version is 'beta' or 'nightly'

I tried to set the rustfmt_iso_date but it seems that it's not a parameters of rust_register_toolchains

[QuentinPerez]

it works with

crates_repository(
...
    rust_toolchain_cargo_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",
    rust_toolchain_rustc_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",
)

but when I try to cross compile for aarch64-apple-ios, the toolchain is missing No matching toolchains found for types @rules_rust//rust:toolchain_type.

Hmm, could you try applying the following diff and see what happens?

Also, you may want to try adding common --@rules_rust//rust/toolchain/channel=nightly to your .bazelrc file if the above doesn't work. This would default the toolchains registerd to nightly toolchains should you have two registered. But my hope is that we can get your repo back to it's original working state without additional toolchains.

but when I try to cross compile for aarch64-apple-ios, the toolchain is missing No matching toolchains found for types @rules_rust//rust:toolchain_type.

Can you show me a build with --toolchain_debug enabled? What previously matched and what is now not matching your cross target?

[QuentinPerez]

there is no cross compile issue with --@rules_rust//rust/toolchain/channel=nightly

@UebelAndre 👋 happy new year !

Just tried the 0.16 and it seems that I still need to specify

build --@rules_rust//rust/toolchain/channel=nightly

and

    rust_toolchain_cargo_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",
    rust_toolchain_rustc_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",

is it normal ? also not sure if it's related but I can't build anymore without CARGO_BAZEL_REPIN=true.
any bazel command ends with an out of date lockfile

    rust_toolchain_cargo_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",
    rust_toolchain_rustc_template = "@rust_{system}_{arch}__{triple}__nightly_tools//:bin/{tool}",

This is expected. It is unfortunately an oversight in recent changes to introduce transitions for toolchain channels. In 0.16.0, fixes were merged but it still seems there's a gap in the user experience here for users of crate_universe. For the out of date lockfiles, I believe changing those templates will invalidate lockfiles and force you to repin. In 0.16.0, the behavior of repinning changed to default to only repinning workspace dependencies. So if you repin I would expect only the hash at the top of the file would change.

@illicitonion I'm wondering if you have any thoughts on how to improve this. The new ability to transition is very valuable in code I work on and so would like to keep the functionality but it does seem users who want to use nightly toolchains must now set an additional flag.

thank you for the answer, about the lockfile even after launching a command with repin=true the next one considers the lockfile out of date, means that I have to specify repin=true all the time.

That’s a major bug then. Can you share your rules_rust and crates_repository definitions?
