Cargo builds deepspeech twice?

[bhamilton2591]

Problem
I first ran this problem by the people responsible for deepspeech-rs. After review, I was told this appeared to be a cargo problem and to open an issue here.

error: aborting due to 2 previous errors
Steps

1. Download native_client from deepspeech from github
   2.clone deepspeech-rs from github
2. from deepspeech-rs directory, execute cargo run --verbose --release --example client

THanks for the report! Can you expand a bit on the reproduction steps? I'm not entirely sure what repositories are in play here?

Deepspeech-rs is a Rust wrapper for deepspeech which is a Mozilla speech to text library written in python.
Clone the deepspeech-rs github repository, https://github.com/RustAudio/deepspeech-rs.git.
From the deepseech-rs directory, there is a Cargo.toml that will build everything needed. The README.md file that contains the steps to build and run a sample program.

You can now invoke the example via:
cargo run --release --example client

Something is fishy from the output. I see these odd things:

• deepspeech and deepspeech-sys are included twice, once from the local git checkout, and once from crates.io.
• libc is using version 0.2.71, but it is currently locked at 0.2.70.

Can you run cargo tree, to maybe see how this is happening? Are you on commit 3f7043c8052e29b63f934b1bacc503e9e44db3b8? Are there any local changes, particularly to Cargo.lock? Do you have any cargo configs, like source replacement?

(FWIW, I cannot reproduce this locally.)

I looked at Cargo.lock, which I haven't examined before, and it had both deepspeech-sys and deepspeech twice. I removed deepspeech-sys from my machine and cloned it again. The Cargo.lock didn't have duplication that the old one did.

I still can't successfully build deepspeech-sys but a different error that I"m still researching, I'm closing this issue.
