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

You will need several development libraries:
* 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 and estimatesmartfee economical node, such as the 0.15 or above.

To Build on Ubuntu 15.10 or above
---------------------

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

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
```

Clone lightning:
```
git clone https://github.com/ElementsProject/lightning.git
cd lightning
```

Build lightning:
```
make
```

Running lightning:
```
bitcoind &
./lightningd/lightningd &
./cli/lightning-cli help
```
**Note**: You may need to include `testnet=1` in `bitcoin.conf`

To Build on FreeBSD 11.1-RELEASE
---------------------

Get dependencies:
```
# pkg install -y autoconf automake git gmake libtool python python3 sqlite3
```

If you don't have Bitcoin installed locally you'll need to install that as well:
```
# pkg install -y bitcoin-daemon bitcoin-utils
```

Clone lightning:
```
$ git clone https://github.com/ElementsProject/lightning.git
$ cd lightning
```

Build lightning:
```
$ gmake
```

Running lightning:

**Note**: Edit your `/usr/local/etc/bitcoin.conf` to include `rpcuser=<foo>` and `rpcpassword=<bar>` first, you may also need to include `testnet=1`

```
# service bitcoind start
$ ./lightningd/lightningd &
$ ./cli/lightning-cli help
```

To Build on Nix{,OS}
--------------------

Untested on MacOS/Windows/Other Linux. Works on NixOS.

Use nix-shell launch a shell with a full clightning dev environment:

```
$ nix-shell -Q -p gdb sqlite autoconf git clang libtool gmp sqlite autoconf \
autogen automake 'python3.withPackages (p: [p.bitcoinlib])' \
valgrind asciidoc --run make
```
