Fedora / CentOS build guide

(updated for Fedora 31)

Preparation

Minimal build requirements:

sudo dnf install boost-devel cmake gcc-c++ git libevent-devel miniupnpc-devel libnatpmp-devel ninja-build openssl-devel python3 zeromq-devel help2man

You can do without the miniupnpc-devel, libnatpmp-devel, zeromq-devel, 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.

BerkeleyDB 5.3 or later is required for the wallet. This can be installed with:

    sudo dnf install libdb-cxx-devel libdb-devel

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

    sudo dnf install qt5-qttools-devel qt5-qtbase-devel qrencode-devel

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

Building Bitcoin Cash Node

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).

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

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:

# to build just the node, no wallet functionality, choose this:
cmake -GNinja .. -DBUILD_BITCOIN_WALLET=OFF -DBUILD_BITCOIN_QT=OFF

# to build the node, with wallet functionality, but without GUI, choose this:
cmake -GNinja .. -DBUILD_BITCOIN_QT=OFF

# to build node and QT GUI client, choose this:
cmake -GNinja ..

Next, finish the build

ninja

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

Optionally, run the tests

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.

sudo ninja install #optional
