Library Requirements
--------------------

You will need several development libraries:
* libprotoc: the Google protocol buffer v2 library, 2.6.0 or above.
* protobuf-c: version 1.1.0 or above.
* libsodium: for crypto.
* libcrypto: (OpenSSL) library for bignum implementation

You will also need a version of bitcoind with segregated witness support:

Build protobuf-c dependency (>= 1.1.0):
```
sudo apt-get install libprotoc-dev
git clone https://github.com/protobuf-c/protobuf-c.git
cd protobuf-c
./autogen.sh
./configure
make
make install
cd ../
```

Clone lightning and initialize submodules:
```
git clone https://github.com/ElementsProject/lightning.git
cd lighting
git submodule init
git submodule update
```

Build lightning:

export LD_LIBRARY_PATH=/usr/local/lib
