OpenBSD build guide

(updated for OpenBSD 7.0)

This guide describes how to build gridcoinresearchd, command-line utilities, and GUI on OpenBSD.

Preparation

Run the following as root to install the base dependencies for building:

pkg_add git gmake libtool libevent boost libzip
pkg_add qt5 libqrencode # (optional for enabling the GUI)
pkg_add autoconf # (select highest version, e.g. 2.71)
pkg_add automake # (select highest version, e.g. 1.16)
pkg_add python # (select highest version, e.g. 3.10)

Resource limits

If the build runs into out-of-memory errors, the instructions in this section might help.

The standard ulimit restrictions in OpenBSD are very strict:

data(kbytes)         1572864

This is, unfortunately, in some cases not enough to compile some .cpp files in the project, (see Bitcoin#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 Gridcoin

Important: use gmake, not make. The non-GNU make will exit with a horrible error.

Preparation:

# Replace this with the autoconf version that you installed. Include only
# the major and minor parts of the version: use "2.71" for "autoconf-2.71p1".
export AUTOCONF_VERSION=2.71

# Replace this with the automake version that you installed. Include only
# the major and minor parts of the version: use "1.16" for "automake-1.16.3".
export AUTOMAKE_VERSION=1.16

./autogen.sh

To configure with gridcoinresearchd:

./configure --with-gui=no \
    MAKE=gmake

To configure with GUI:

./configure --with-gui=yes \
    MAKE=gmake

Build and run the tests:

gmake # use "-j N" here for N parallel jobs
gmake check
