cargo build: error: failed to select a version for ibc-proto.

[taitruong]

I was trying to build v1.7.0 using cargo build --release --bin hermes, but get this error:

    Updating crates.io index
error: failed to select a version for `ibc-proto`.
    ... required by package `ibc-relayer v0.26.0 (/home/ttruong/data/development/hermes/crates/relayer)`
versions that meet the requirements `^0.38.0` (locked to 0.38.0) are: 0.38.0

the package `ibc-relayer` depends on `ibc-proto`, with features: `tonic` but `ibc-proto` does not have these features.
 It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

I was able to build v1.6.0 though.

This is weird, since Hermes builds fine on CI and I am also unable to reproduce this locally.

Also this error message is plain wrong:

the package ibc-relayer depends on ibc-proto, with features: tonic

since ibc-relayer does not depend on ibc-proto with the tonic feature.

Which commit are you building from?

Maybe do a cargo clean followed by cargo update and try building again?

[taitruong]

seems like it comes from ibc-proto: cargo add ibc-proto --package ibc-relayer-types

Error:

And yes, I did a cargo clean and working on v1.7.0 branch.

Ah i see then yeah the v1.7.0 tag is a bit borked. You can either install it from crates.io or build from master if that's okay with you. Sorry about that!

[taitruong]

Can you create a new release?

Are you using Rust v1.70.0? If so, the issue should be solved by upgrading to Rust v1.71.0 rust-lang/cargo#12130
