Hi.
Thanx for the detailed description. I have just tried to implement this in my cloud.
Downloaded stable libreoffice 5.1.4.2 & libreoffice on-line from the git repository.
After compilation and trying to start loolwsd I see:
frk-32080-00 00:00:00.073630 [ loolforkit ] No lok_preinit symbol in /opt/libreoffice-5.1.4.2/lib/libreoffice/program/libsofficeapp.so: /opt/libreoffice-5.1.4.2/lib/libreoffice/program/libsofficeapp.so: undefined symbol: lok_preinit
wsd-32071-00 00:00:02.021066 [ loolwsd ] Child process [32080] exited with code: 70.Which problem causes this and how to solve it? The same error appeared also when I tried to use libreoffice4 from the OS. Googling didn’t help 
Thanx.
