(updated for OpenBSD 6.2)
This guide describes how to build kevacoind 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.
Run the following as root to install the base dependencies for building:
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/kevacoin-project/kevacoin.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.
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="$PWD/db4"
Important: use gmake
, not make
. The non-GNU make
will exit with a horrible error.
Preparation:
export AUTOCONF_VERSION=2.69 # replace this with the autoconf version that you installed
export AUTOMAKE_VERSION=1.15 # replace this with the automake version that you installed
./autogen.sh
Make sure BDB_PREFIX
is set to the appropriate path from the above steps.
To configure with wallet:
./configure --with-gui=no CC=cc CXX=c++ \
BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include"
To configure without wallet:
./configure --disable-wallet --with-gui=no CC=cc CXX=c++
Build and run the tests:
gmake # use -jX here for parallelism
gmake check
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.
