This guide describes how to build bitcoind and command-line utilities on OpenBSD.
As OpenBSD is most common as a server OS, we will not bother with the GUI.
OpenBSD is most commonly used as a server OS, so this guide does not contain instructions for building the GUI.

GCC
GCC

-------
The default C++ compiler that comes with OpenBSD 5.9 is g++ 4.2. This version is old (from 2007), and is not able to compile the current version of Bitcoin Core, primarily as it has no C++11 support, but even before there were issues. So here we will be installing a newer compiler:
The default C++ compiler that comes with OpenBSD 6.2 is g++ 4.2.1. This version is old (from 2007), and is not able to compile the current version of Bitcoin Core because it has no C++11 support. We'll install a newer version of GCC:
```bash
```bash
pkg_add g++ # (select newest 4.x version, e.g. 4.9.3)
pkg_add g++
```
```
This compiler will not overwrite the system compiler, it will be installed as `egcc` and `eg++` in `/usr/local/bin`.
### Building boost
Do not use `pkg_add boost`! The boost version installed thus is compiled using the `g++` compiler not `eg++`, which will result in a conflict between `/usr/local/lib/libestdc++.so.XX.0` and `/usr/lib/libstdc++.so.XX.0`, resulting in a test crash:
test_bitcoin:/usr/lib/libstdc++.so.57.0: /usr/local/lib/libestdc++.so.17.0 : WARNING: symbol(_ZN11__gnu_debug17_S_debug_me ssagesE) size mismatch, relink your program
...
Segmentation fault (core dumped)
This makes it necessary to build boost, or at least the parts used by Bitcoin Core, manually:
This compiler will not overwrite the system compiler, it will be installed as `egcc` and `eg++` in `/usr/local/bin`.
```
# Pick some path to install boost to, here we create a directory within the bitcoin directory

However, this does not appear to work. Compilation succeeds, but link fails
with many 'local symbol discarded' errors:
