NetBSD Build Guide

Updated for NetBSD 10.0

This guide describes how to build bitcoind, command-line utilities, and GUI on NetBSD.

Preparation

1. Install Required Dependencies

Install the required dependencies the usual way you install software on NetBSD. The example commands below use pkgin.

pkgin install git cmake pkg-config boost-headers libevent

NetBSD currently ships with an older version of gcc than is needed to build. You should upgrade your gcc and then pass this new version to the configure script.

For example, grab gcc12:

pkgin install gcc12

Then, when configuring, pass the following:

cmake -B build
    ...
    -DCMAKE_C_COMPILER="/usr/pkg/gcc12/bin/gcc" \
    -DCMAKE_CXX_COMPILER="/usr/pkg/gcc12/bin/g++" \
    ...

See dependencies.md for a complete overview.

2. Clone Bitcoin Repo

Clone the Bitcoin Core repository to a directory. All build scripts and commands will run from this directory.

git clone https://github.com/bitcoin/bitcoin.git

3. Install Optional Dependencies

Wallet Dependencies

It is not necessary to build wallet functionality to run bitcoind or the GUI.

Descriptor Wallet Support

sqlite3 is required to enable support for descriptor wallets.

pkgin install sqlite3

Legacy Wallet Support

db4 is required to enable support for legacy wallets.

pkgin install db4

GUI Dependencies

Qt5

Bitcoin Core includes a GUI built with the cross-platform Qt Framework. To compile the GUI, we need to install the necessary parts of Qt, the libqrencode and pass -DBUILD_GUI=ON. Skip if you don't intend to use the GUI.

pkgin install qt5-qtbase qt5-qttools

libqrencode

The GUI will be able to encode addresses in QR codes unless this feature is explicitly disabled. To install libqrencode, run:

pkgin install qrencode

Otherwise, if you don't need QR encoding support, use the -DWITH_QRENCODE=OFF option to disable this feature in order to compile the GUI.

Test Suite Dependencies

There is an included test suite that is useful for testing code changes when developing. To run the test suite (recommended), you will need to have Python 3 installed:

pkgin install python39

Building Bitcoin Core

1. Configuration

There are many ways to configure Bitcoin Core. Here is an example that explicitly disables the wallet and GUI:

cmake -B build -DENABLE_WALLET=OFF -DBUILD_GUI=OFF

Run cmake -B build -LH to see the full list of available options.

2. Compile

Build and run the tests:

cmake --build build     # Use "-j N" for N parallel jobs.
ctest --test-dir build  # Use "-j N" for N parallel tests. Some tests are disabled if Python 3 is not available.
