Instead of maintaining not-easily-tested instructions for building BerkeleyDB in doc/build-unix.md, package the installation as a script in contrib/. This allows shared usage from a number of contexts, e.g. Docker. Thanks to @jonasschnelli, @laanwj for feedback.

OpenBSD build guide
|
|
======================
|
|
(updated for OpenBSD 6.2)
|
|
|
|
This guide describes how to build bitcoind and command-line utilities on OpenBSD.
|
|
|
|
OpenBSD is most commonly used as a server OS, so this guide does not contain instructions for building the GUI.
|
|
|
|
Preparation
|
|
-------------
|
|
|
|
Run the following as root to install the base dependencies for building:
|
|
|
|
```bash
|
|
pkg_add git gmake libevent libtool
|
|
pkg_add autoconf # (select highest version, e.g. 2.69)
|
|
pkg_add automake # (select highest version, e.g. 1.15)
|
|
pkg_add python # (select highest version, e.g. 3.6)
|
|
pkg_add boost
|
|
|
|
git clone https://github.com/bitcoin/bitcoin.git
|
|
```
|
|
|
|
See [dependencies.md](dependencies.md) for a complete overview.
|
|
|
|
GCC
|
|
-------
|
|
|
|
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
|
|
pkg_add g++
|
|
```
|
|
|
|
This compiler will not overwrite the system compiler, it will be installed as `egcc` and `eg++` in `/usr/local/bin`.
|
|
|
|
### Building BerkeleyDB
|
|
|
|
BerkeleyDB is only necessary for the wallet functionality. To skip this, pass `--disable-wallet` to `./configure`.
|
|
|
|
It is recommended to use Berkeley DB 4.8. You cannot use the BerkeleyDB library
|
|
from ports, for the same reason as boost above (g++/libstd++ incompatibility).
|
|
If you have to build it yourself, you can use [the installation script included
|
|
in contrib/](contrib/install_db4.sh) like so
|
|
|
|
```shell
|
|
./contrib/install_db4.sh `pwd` CC=egcc CXX=eg++ CPP=ecpp
|
|
```
|
|
|
|
from the root of the repository.
|
|
|
|
### Resource limits
|
|
|
|
The standard ulimit restrictions in OpenBSD are very strict:
|
|
|
|
data(kbytes) 1572864
|
|
|
|
This, unfortunately, may no longer be enough to compile some `.cpp` files in the project,
|
|
at least with GCC 4.9.4 (see issue [#6658](https://github.com/bitcoin/bitcoin/issues/6658)).
|
|
If your user is in the `staff` group the limit can be raised with:
|
|
|
|
ulimit -d 3000000
|
|
|
|
The change will only affect the current shell and processes spawned by it. To
|
|
make the change system-wide, change `datasize-cur` and `datasize-max` in
|
|
`/etc/login.conf`, and reboot.
|
|
|
|
### Building Bitcoin Core
|
|
|
|
**Important**: use `gmake`, not `make`. The non-GNU `make` will exit with a horrible error.
|
|
|
|
Preparation:
|
|
```bash
|
|
export AUTOCONF_VERSION=2.69 # replace this with the autoconf version that you installed
|
|
export AUTOMAKE_VERSION=1.15 # replace this with the automake version that you installed
|
|
./autogen.sh
|
|
```
|
|
Make sure `BDB_PREFIX` is set to the appropriate path from the above steps.
|
|
|
|
To configure with wallet:
|
|
```bash
|
|
./configure --with-gui=no CC=egcc CXX=eg++ CPP=ecpp \
|
|
BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include"
|
|
```
|
|
|
|
To configure without wallet:
|
|
```bash
|
|
./configure --disable-wallet --with-gui=no CC=egcc CXX=eg++ CPP=ecpp
|
|
```
|
|
|
|
Build and run the tests:
|
|
```bash
|
|
gmake # use -jX here for parallelism
|
|
gmake check
|
|
```
|
|
|
|
Clang
|
|
------------------------------
|
|
|
|
```bash
|
|
pkg_add llvm
|
|
|
|
./configure --disable-wallet --with-gui=no CC=clang CXX=clang++
|
|
gmake # use -jX here for parallelism
|
|
gmake check
|
|
```
