d11020019a0c93dcc56859cdfcd9f0c6a777424f Add OpenBSD instructions for building the Qt GUI (grubles) Pull request description: Using OpenBSD as a desktop OS is prevalent enough IMO to warrant updating the documentation for building the GUI. ACKs for top commit: fanquake: ACK d11020019a0c93dcc56859cdfcd9f0c6a777424f - looks fine. Have not tested.

OpenBSD build guide
(updated for OpenBSD 6.2)
This guide describes how to build dashd, dash-qt, and command-line utilities on OpenBSD.
Preparation
Run the following as root to install the base dependencies for building:
pkg_add git gmake libevent libtool
pkg_add qt5 # (optional for enabling the GUI)
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 gmp
pkg_add boost
git clone https://github.com/dashpay/dash.git
See dependencies.md for a complete overview.
Important: From OpenBSD 6.2 onwards a C++11-supporting clang compiler is
part of the base image, and while building it is necessary to make sure that this
compiler is used and not ancient g++ 4.2.1. This is done by appending
CC=cc CXX=c++
to configuration commands. Mixing different compilers
within the same executable will result in linker errors.
Building BerkeleyDB
BerkeleyDB is only necessary for the wallet functionality. To skip this, pass
--disable-wallet
to ./configure
and skip to the next section.
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/ like so:
./contrib/install_db4.sh `pwd` CC=cc CXX=c++
from the root of the repository. Then set BDB_PREFIX
for the next section:
export BDB_PREFIX="$PWD/db4"
Building Dash Core
Important: Use gmake
(the non-GNU make
will exit with an error).
Preparation:
export AUTOCONF_VERSION=2.69 # replace this with the autoconf version that you installed
export AUTOMAKE_VERSION=1.15 # replace this with the automake version that you installed
./autogen.sh
Make sure BDB_PREFIX
is set to the appropriate path from the above steps.
To configure with wallet:
./configure --with-gui=no CC=cc CXX=c++ \
BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
BDB_CFLAGS="-I${BDB_PREFIX}/include" \
MAKE=gmake
To configure without wallet:
./configure --disable-wallet --with-gui=no CC=cc CXX=c++ MAKE=gmake
To configure with GUI:
./configure --with-gui=yes CC=cc CXX=c++ \
BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
BDB_CFLAGS="-I${BDB_PREFIX}/include" \
MAKE=gmake
Build and run the tests:
gmake # use -jX here for parallelism
gmake check
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, unfortunately, in some cases not enough to compile some .cpp
files in the project,
(see issue #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.
