issues compiling ethcore/parity with rust 1.15.1

[derhuerst]

I can't compile ethcore/parity at e9eed5206. Several dependencies use serde for procedural macros.

git checkout e9eed5206
cargo build --release --verbose

I'm not proficient in the build architecture of rust, but willing to help debug this further! Let me know if any information is missing.

I was not able to reproduce this with rustc 1.15.1 against ethcore/parity@e9eed5206 nor rust-ethereum/ethabi@ff7e598 nor paritytech/jsonrpc@86d7a89. All of those built successfully.

Does it still fail for you if you compile ethabi or jsonrpc directly?

I should have mentioned that I use rustc 1.15.1 from Homebrew.

Don't get any errors with rust 1.15.1 from rustup. Sorry for the noise!

This should no longer be a problem in Homebrew due to Homebrew/homebrew-core#14490.
