### Building from source ### Building from source
##### Ubuntu 14.04, 15.04, 15.10 First (if you don't already have it) get multirust:
- Linux:
```bash ```bash
# install rocksdb
add-apt-repository ppa:ethcore/ethcore
apt-get update
apt-get install -y --force-yes librocksdb-dev
# install multirust
curl -sf https://raw.githubusercontent.com/brson/multirust/master/blastoff.sh | sh -s -- --yes
# install beta
multirust update beta
# download and build parity
git clone https://github.com/ethcore/parity
cd parity
# parity should be build with rust beta
multirust override beta
# build in release
cargo build --release
```
##### Other Linux
```bash
# install rocksdb
git clone --tag v4.1 --depth=1 https://github.com/facebook/rocksdb.git
cd rocksdb
make shared_lib
sudo cp -a librocksdb.so* /usr/lib
sudo ldconfig
cd ..
# install rust beta

multirust update beta
# download and build parity
git clone https://github.com/ethcore/parity
cd parity
# parity should be build with rust beta
multirust override beta
# build in release
cargo build --release
``` ```
##### OSX with Homebrew - OSX with Homebrew:
```bash
brew update && brew install multirust
```
Then, download and build Parity:
```bash ```bash
# install rocksdb && multirust # download Parity code
brew update
brew install rocksdb
brew install multirust
# install beta
multirust update beta
# download and build parity
git clone https://github.com/ethcore/parity git clone https://github.com/ethcore/parity
cd parity cd parity
# use rust beta for building parity # parity should be built with rust beta
multirust override beta multirust override beta
# build in release mode
cargo build --release cargo build --release
``` ```
