Can not build on Linux

[WildPenquin]

Hi,

I can not build mcp on Linux:

$ cargo build --release
warning: An explicit [[bin]] section is specified in Cargo.toml which currently
disables Cargo from automatically inferring other binary targets.
This inference behavior will change in the Rust 2018 edition and the following
files will be included as a binary target:

* /data/home/ville/usr/src/mcp/src/bin/tape.rs
* /data/home/ville/usr/src/mcp/src/bin/wav.rs
* /data/home/ville/usr/src/mcp/src/bin/args.rs
* /data/home/ville/usr/src/mcp/src/bin/file.rs

This is likely to break cargo build or cargo test as these files may not be
ready to be compiled as a binary target today. You can future-proof yourself
and disable this warning by adding `autobins = false` to your [package]
section. You may also move the files to a location where Cargo would not
automatically infer them to be a target, such as in subfolders.

For more information on this warning you can consult

Note: it is not only on Linux. It is also in Mac. Probably because of some library does not work well with modern Rust on given version.

Checking...

[apoloval]

Yes, we were using rustc_serialize, which is deeply unsupported right now by Docopt.

Fixed in 9b15971.

[apoloval]

No, it is still failing in Linux due to some other dependencies: https://travis-ci.org/apoloval/mcp/builds/508443943

Reopening...
