Qtum is capable to run on small devices, it requires quite few CPU power, memory and storage to mine coins. But the binaries released by Qtum official are not suitable for Raspberry Pi Zero or First Generations. Here is a tutorial on how to build Qtum on a raspi. In this tutorial, we assume that you are using a raspbian system.
Generally, a raspi is capable to build qtum, but we need:
- an SD card with at least 8G space and at least 6G available;
- Internet connection is also required.
Qtum requires quite few memory to run. However it is not true for building Qtum. It requires over 1.5G memory to build, which is much more than a raspi has. So we have to set the swap space to 2G:
# modify swap size to at least 2GB sudo sed -ri 's/CONF_SWAPSIZE=[0-9]+/CONF_SWAPSIZE=2048/' /etc/dphys-swapfile sudo systemctl restart dphys-swapfile
We cat install building tools and most dependencies with apt:
# install dependencies sudo apt-get install git autoconf libtool libboost-dev libboost-system-dev libboost-filesystem-dev libboost-thread-dev libboost-chrono-dev libboost-random-dev libssl-dev libevent-dev libboost-test-dev
If you need the Qt GUI, additionally run:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler qrencode
mkdir build_qtum cd build_qtum
Unfortunately we can't install Berkeley DB 4.8 dependency on a raspbian via apt, so we need to build it ourselves:
# to build berkeley db 4.8 wget http://download.oracle.com/berkeley-db/db-4.8.30.tar.gz tar -xzf db-4.8.30.tar.gz pushd db-4.8.30/build_unix ../dist/configure --prefix=/usr/local --enable-cxx make # this would take around 50 minutes on a raspi 0 W sudo make install popd
First we have to get the source:
git clone https://github.com/qtumproject/qtum.git cd qtum
Then we should switch to a stable release tag, for now the latest release for Qtum is
mainnet-ignition-v0.17.5, but you should always build a latest one.
git checkout mainnet-ignition-v0.17.5
Then init submodules:
git submodule update --init --recursive
Finally the most common way to build and install a software:
./autogen.sh ./configure make sudo make install
It is highly recommended that you run the
make step inside a virtual console like
tmux because the step takes more than 20 HOURS. By using a virtual console, you don't need to keep the ssh session during its building. To do this, run these commands before
sudo apt-get install screen screen -S build
And when you started making, you may leave the screen by pressing Ctrl + A then D, and you may go back to it with this command:
Boom! Now you have Qtum installed on your raspi!
