Cross-compilling Bulwark wallet for armhf architecture (Raspberry Pi 2)

Build successful tested on Ubuntu Server 18.04 LTS (x86-64)

1. Install build essential packages (for non-GUI wallet)

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3 libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev git

2. Install ARM cross compiler toolchain

sudo apt-get install g++-arm-linux-gnueabihf

3. Clone bulwark repo

git clone https://github.com/bulwark-crypto/Bulwark.git

4. Switch branch to specific wallet version

cd Bulwark
git checkout 1.3.1

5. Pull and build all dependencies

cd depends
make HOST=arm-linux-gnueabihf NO_QT=1 NO_UPNP=1 -j$(nproc)

6. Generate configure file

cd ..
./autogen.sh

7. Change some autogenerated options (if you need so)

Below disabled graphical UI, UPNP (firewall-jumping support) and ZMQ notifications

./configure --prefix=`pwd`/depends/arm-linux-gnueabihf --with-gui=no --without-miniupnpc --disable-zmq

8. Compile using all cores

make -j$(nproc)

9. Find binaries built in last step and manual copy them to RPi 2 device

find src -maxdepth 1 -type f -executable -exec file {} \; | grep -Eo "^([^,]+,){6}"

On RPi 2 device (tested with ArchLinuxARM-rpi-2)

Better to do all steps from non-root user

1. Copy binaries to system directory

sudo cp bulwarkd bulwark-cli bulwark-tx /usr/local/bin

2. Write required parameters to bulwark.conf

Add staking=1 if you want to stake coins

cat > ~/.bulwark/bulwark.conf << EOL
rpcuser=bulwark
rpcpassword=some_strong_password
EOL

3. Create systemd service

Change username SOMEUSER to yours

sudo cat > /etc/systemd/system/bulwarkd.service << EOL

4. Activate and run service

sudo systemctl enable bulwarkd
sudo systemctl start bulwarkd

5. Check wallet status (will take some time to sync blocks)

watch bulwark-cli getinfo
