Parity installation problem in OSX

Question

During the installation I've got at the end this:

Last 15 lines from /Users/maksim/Library/Logs/Homebrew/parity/02.multirust:

 error: aborting due to previous error
 Build failed, waiting for other jobs to finish...
 error: Could not compile `heapsize`.

 To learn more, run the command again with --verbose.

Before I do --verbose, may be someone already can see what the problem is?

Thanks from not so much experienced Mac user!

Update: During installation according to @Ellis get the following:

maksims-mbp:parity maksim$ brew update && brew install multirust
Already up-to-date.
Warning: multirust-0.8.0 already installed
maksims-mbp:parity maksim$ multirust default stable
multirust: installing toolchain 'stable'

Any ideas on how to fix it? Does it have something to do with "not having 'gpg' "?

Answer 1

I have worked on parity few weeks ago on OS X. This guide is for Parity 1.2. The build is very long. I suppose you have installed homebrew.

Homebrew (juin 2016) have a preinstalled version of Parity : version 1.1. To avoid any conflict, let's delete this one and jump on 1.2 version :

user:~ brew remove parity

Ethcore provides a unique command to install Parity, but to install version 1.2, you shouldn't use it, but rather proceed like this :

user:~ brew update && brew install multirust
user:~ multirust default stable
user:~ cd && git clone https://github.com/ethcore/parity.git && cd parity
user:~ cargo run --release
user:~ sudo cp parity//target/release/parity /usr/local/bin/

This command install the rust compiler and download all that is needed from github. After a few moment, parity is deployed on your system.
