lightning/INSTALL.md

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.
* libsqlite3: for database support.
* libgmp: for secp256k1

For actually doing development and running the tests, you will also need:
* pip3: to install python-bitcoinlib
* asciidoc: for formatting the man pages (if you change them)
* valgrind: for extra debugging checks

You will also need a version of bitcoind with segregated witness support,
such as the 0.13 or above.

To Build on Ubuntu 16.04
---------------------

Get dependencies:
```
sudo apt-get install -y autoconf build-essential git libtool libprotobuf-c-dev libgmp-dev libsqlite3-dev python3 net-tools
```

If you don't have Bitcoin installed locally you'll need to install that as well:
```
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install -y bitcoind
```

For development or running tests, get additional dependencies:
```
sudo apt-get install -y asciidoc valgrind python3-pip
sudo pip3 install python-bitcoinlib
```
