Create a deb package for rspamd on armhf (Raspberry Pi)

build-rspamd.md

Install build and runtime dependencies:

git clone --recursive https://github.com/vstakhov/rspamd.git
cd rspamd

For master:

sudo apt install devscripts fakeroot debhelper libcurl4-openssl-dev dh-systemd libjemalloc-dev libunwind-dev ragel libevent-dev lua5.1 liblua5.1-dev cmake sqlite3 libmagic-dev libsqlite3-dev libicu-dev libglib2.0-dev libssl-dev libsodium-dev

Build and create deb package

mkdir build
cd build
cmake ..
make dist
tar xvf rspamd-2.0.tar.xz
cd rspamd-2.0
debuild -uc -us
cd ..
dpkg -i *.deb

For 1.9.4

Replace the corresponding lines in the above snippet

git checkout tags/1.9.4
...
sudo apt install devscripts fakeroot debhelper dh-systemd libjemalloc-dev libunwind-dev cmake ragel libevent-dev lua5.1 liblua5.1-dev libsqlite3-0=3.16.2-5+deb9u1 libsqlite3-dev sqlite3 libmagic1=1:5.30-1+deb9u2 libmagic-dev libfann-dev libfann2 libluajit-5.1-common=2.1.0~beta3+dfsg-5.1~bpo9+1 luajit libluajit-5.1
...
tar xvf rspamd-1.9.4.tar.xz
...

And it runs:

service rspamd status                                                                                                                           ● rspamd.service - rapid spam filtering system

Also marked this package on hold, so apt wont ever replace it with: apt-mark hold rspamd
