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 FreeBSD
OS version: FreeBSD 11.1-RELEASE or above
Get dependencies:
# pkg install -y \
autoconf automake git gmp asciidoc 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
$ gmake install
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 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
To Build on macOS
Assume you have Xcode and HomeBrew installed on your Mac. Get dependencies:
$ brew install autoconf automake libtool python3 gmp libsodium gnu-sed
If you don't have bitcoind installed locally you'll need to install that as well:
$ brew install \
berkeley-db4 boost miniupnpc openssl pkg-config protobuf qt libevent
$ git clone https://github.com/bitcoin/bitcoin
$ cd bitcoin
$ ./autogen.sh
$ ./configure
$ make & make install
Clone lightning:
$ git clone https://github.com/ElementsProject/lightning.git
$ cd lightning
Build lightning:
$ make
Running lightning:
Note: Edit your ~/Library/Application\ Support/Bitcoin/bitcoin.conf
to include rpcuser=<foo> and rpcpassword=<bar> first, you may also
need to include testnet=1
bitcoind &
./lightningd/lightningd &
./cli/lightning-cli help
To cross-compile for Android
Make a standalone toolchain as per https://developer.android.com/ndk/guides/standalone_toolchain.html. For c-lightning you must target an API level of 24 or higher.
Depending on your toolchain location and target arch, source env variables such as:
export PATH=$PATH:/path/to/android/toolchain/bin
# Change next line depending on target device arch
target_host=arm-linux-androideabi
export AR=$target_host-ar
export AS=$target_host-clang
export CC=$target_host-clang
export CXX=$target_host-clang++
export LD=$target_host-ld
export STRIP=$target_host-strip
Two makefile targets should not be cross-compiled so we specify a native CC:
make CC=clang clean ccan/tools/configurator/configurator
make clean -C ccan/ccan/cdump/tools \
&& make CC=clang -C ccan/ccan/cdump/tools
Install the qemu-user package.
This will allow you to properly configure
the build for the target device environment.
Build with:
BUILD=x86_64 HOST=arm-linux-androideabi \
make PIE=1 DEVELOPER=0 \
CONFIGURATOR_CC="arm-linux-androideabi-clang -static"
To cross-compile for Raspberry Pi
Obtain the official Raspberry Pi toolchains. This document assumes compilation will occur towards the Raspberry Pi 3 (arm-linux-gnueabihf as of Mar. 2018). In addition, obtain and install cross-compiled versions of sqlite 3 and gmp.
Depending on your toolchain location and target arch, source env variables will need to be set. They can be set from the command line as such:
export PATH=$PATH:/path/to/arm-linux-gnueabihf/bin
# Change next line depending on specific Raspberry Pi device
target_host=arm-linux-gnueabihf
export AR=$target_host-ar
export AS=$target_host-as
export CC=$target_host-gcc
export CXX=$target_host-g++
export LD=$target_host-ld
export STRIP=$target_host-strip
Install the qemu-user package. This will allow you to properly configure the build for the target device environment. Then, build with the following commands. (A 64-bit build system is assumed here.)
make CC=gcc clean ccan/tools/configurator/configurator
BUILD=x86_64 HOST=arm-linux-gnueabihf make PIE=1 DEVELOPER=0 CONFIGURATOR_CC="arm-linux-gnueabihf-gcc -static" LDFLAGS="-L/path/to/gmp-and-sqlite/lib" CFLAGS="-std=gnu11 -I /path/to/gmp-and-sqlite/include -I . -I ccan -I external/libwally-core/src/secp256k1/include -I external/libsodium/src/libsodium/include -I external/jsmn -I external/libwally-core/include -I external/libbacktrace -I external/libbase58"
The compilation will eventually fail due to a compile error in the cdump CCAN module. Recompile the module, and then re-run the make system.
make clean -C ccan/ccan/cdump/tools
make CC=gcc -C ccan/ccan/cdump/tools
BUILD=x86_64 HOST=arm-linux-gnueabihf make PIE=1 DEVELOPER=0 CONFIGURATOR_CC="arm-linux-gnueabihf-gcc -static" LDFLAGS="-L/path/to/gmp-and-sqlite/lib" CFLAGS="-std=gnu11 -I /path/to/gmp-and-sqlite/include -I . -I ccan -I external/libwally-core/src/secp256k1/include -I external/libsodium/src/libsodium/include -I external/jsmn -I external/libwally-core/include -I external/libbacktrace -I external/libbase58"
