Arch Linux build guide

Preparation

You will need the following dependencies:

bash pacman -S boost cmake git libevent ninja python miniupnpc libnatpmp zeromq help2man gmp zlib

You can do without the miniupnpc, libnatpmp, zeromq, and help2man packages, then you just need to respectively pass -DENABLE_UPNP=OFF, -DENABLE_NATPMP=OFF, -DBUILD_BITCOIN_ZMQ=OFF, or -DENABLE_MAN=OFF on the cmake command line.

If you want to build the GUI client bitcoin-qt Qt 5 is necessary. To build with Qt 5 you need the following packages installed:

bash pacman -S qt5-base qt5-tools qrencode

You can do without the qrencode package, just pass -DENABLE_QRCODE=OFF on the cmake command line.

Building

Once you have installed the required dependencies (see sections above), you can build Bitcoin Cash Node as such:

First fetch the code (if you haven't done so already).

bash git clone https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node.git

Change to the BCN directory, make build dir, and change to that directory

bash cd bitcoin-cash-node/ mkdir build cd build

Next you need to choose between building just the node, the node with wallet support, or the node and the QT client.

Choose one:

```bash

to build just the node, no wallet functionality, choose this:

cmake -GNinja .. -DBUILD_BITCOIN_WALLET=OFF -DBUILD_BITCOIN_QT=OFF ```

```bash

to build the node, with wallet functionality, but without GUI, choose this:

cmake -GNinja .. -DBUILD_BITCOIN_QT=OFF ```

```bash

to build node and QT GUI client, choose this:

cmake -GNinja .. ```

Next, finish the build

bash ninja

You will find the bitcoind, bitcoin-cli, bitcoin-tx (and optionally bitcoin-qt) binaries in /build/src/(qt).

Optionally, run the tests

bash ninja check # recommended

After a successful test you can install the newly built binaries to your bin directory. Note that this will probably overwrite any previous version installed, including binaries from different sources.

bash sudo ninja install #optional
