# NetBSD Build Guide
2018-01-08 20:26:00 +01:00
Updated for NetBSD [9.2](https://netbsd.org/releases/formal-9/NetBSD-9.2.html).
2018-01-08 20:26:00 +01:00
This guide describes how to build bitcoind, command-line utilities, and GUI on NetBSD.
2018-01-08 20:26:00 +01:00
## Preparation
2018-01-08 20:26:00 +01:00
### 1. Install Required Dependencies
Install the required dependencies the usual way you [install software on NetBSD](https://www.netbsd.org/docs/guide/en/chap-boot.html#chap-boot-pkgsrc).
The example commands below use `pkgin`.
```bash
pkgin install autoconf automake libtool pkg-config git gmake boost libevent
2018-01-08 20:26:00 +01:00
```
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 `gcc9`:
```
pkgin install gcc9
```
Then, when configuring, pass the following:
```bash
./configure
...
CC="/usr/pkg/gcc9/bin/gcc" \
CXX="/usr/pkg/gcc9/bin/g++" \
...
2018-01-08 20:26:00 +01:00
```
See [dependencies.md](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.
```bash
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](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md).
```bash
pkgin install sqlite3
```
###### Legacy Wallet Support
`db4` is required to enable support for legacy wallets.
```bash
pkgin install db4
```
#### GUI Dependencies
Bitcoin Core includes a GUI built with the cross-platform Qt Framework. To compile the GUI, we need to install `qt5`.
```bash
pkgin install qt5
```
The GUI can encode addresses in a QR Code. To build in QR support for the GUI, install `qrencode`.
```bash
pkgin install qrencode
```
#### 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:
```bash
pkgin install python37
2018-01-08 20:26:00 +01:00
```
### Building Bitcoin Core
**Note**: Use `gmake` (the non-GNU `make` will exit with an error).
### 1. Configuration
There are many ways to configure Bitcoin Core. Here is an example that
explicitly disables the wallet and GUI:
```bash
2018-01-08 20:26:00 +01:00
./autogen.sh
./configure --without-wallet --with-gui=no \
CPPFLAGS="-I/usr/pkg/include" \
MAKE=gmake
```
For a full list of configuration options, see the output of `./configure --help`
### 2. Compile
Build and run the tests:
```bash
gmake # use "-j N" here for N parallel jobs
gmake check # Run tests if Python 3 is available
2018-01-08 20:26:00 +01:00
```
