## Installing from source



Installing `pzec` from source requires `rustc` and `cargo`.



Minimal supported version is `rustc 1.23.0 (766bd11c8 2018-01-01)`



#### Install rustc and cargo



Both `rustc` and `cargo` are a part of rust tool-chain.



An easy way to install the stable binaries for Linux and Mac is to run this in your shell:



```

curl https://sh.rustup.rs -sSf | sh

```



Windows binaries can be downloaded from [rust-lang website](https://forge.rust-lang.org/other-installation-methods.html#standalone).



#### Install C and C++ compilers



You will need the cc and gcc compilers to build some of the dependencies.



On macOS 



`build-essential` is a Debian package. On macOS you will need to make sure you have Xcode installed. If you already have Homebrew installed, you probably also already have the Xcode tools installed as well. If not, you can run the command below:

```

xcode-select --install

```



On Linux

```

sudo apt-get update

sudo apt-get install build-essential

```



#### Clone and build pzec



Now let's clone `pzec` and enter it's directory:



```

git clone https://github.com/paritytech/parity-zcash

cd parity-zcash



# builds pzec in release mode

cargo build -p pzec --release

```



`pzec` is now available at `./target/release/pzec`.



## Installing the snap



In any of the [supported Linux distros](https://snapcraft.io/docs/core/install):



```

sudo snap install parity-zcash --edge

```



## Running tests



`pzec` has internal unit tests and it conforms to external integration tests.



#### Running unit tests



Assuming that repository is already cloned, we can run unit tests with this command:



```

cargo test --all

```



## Going online



By default parity connects to Zcash seednodes. Full list is [here](./pzec/seednodes.rs).



To start syncing the main network, just start the client without any arguments:



```

./target/release/pzec

```



To start syncing the testnet:



```

./target/release/pzec --testnet

```



To not print any syncing progress add `--quiet` flag:



```

./target/release/pzec --quiet

```



## Importing zcashd database



It it is possible to import existing `zcashd` database:



```

# where $ZCASH_DB is path to your zcashd database. By default:

# on macOS: "/Users/user/Library/Application Support/Zcash"

# on Linux: "~/.zcash"

./target/release/pzec import "$ZCASH_DB/blocks"

```



By default, import verifies the imported blocks. You can disable this, by adding the `--verification-level=none` option.



```

./target/release/pzec --verification-level=none import "$ZCASH_DB/blocks"

```



## Command line interface



Full list of CLI options, which is available under `pzec --help`: see [here](CLI.md)



## Logging



This is a section only for developers and power users.



You can enable detailed client logging by setting the environment variable `RUST_LOG`, e.g.,



```

RUST_LOG=verification=info ./target/release/pzec

```



`pzec` started with this environment variable will print all logs coming from `verification` module with verbosity `info` or higher. Available log levels are:



- `error`

- `warn`

- `info`

- `debug`

- `trace`



It's also possible to start logging from multiple modules in the same time:



```

RUST_LOG=sync=trace,p2p=trace,verification=trace,db=trace ./target/release/pzec

```



## Internal documentation



Once released, `pzec` documentation will be available [here][doc-url]. Meanwhile it's only possible to build it locally:



```

cd parity-zcash

./tools/doc.sh

open target/doc/pzec/index.html

```
