Script collection to build libreoffice online or collabora online.

Supported Linux Distributions:

  • Ubuntu 16.04.x, xenial
  • Ubuntu 18.04.x, bionic
  • Debian 8.x, jessie
  • Debian 9.x, stretch

Updates the system, installs and sets up the required packages. Finally builds libreoffice and libreoffice online.


A minimal or standard installation of a supported distribution as VM or on real Hardware is required. For flawless building, the following system resources are recommended:

  • Disk space: >= 32 GByte
  • Memory: >= 4 GByte
  • Number of CPU cores: >= 4

Additionally you need an user account with sudo capability. Building as user root does not work.


Before you start please customize the configuration. Copy config/ to config/ Adjust config/ to your needs.

Especially take care for the settings of the two variables LOOL_MAX_CON and LOOL_MAX_DOC. These two variables define the limits for the allowed number of simultaneous connections to your online office and the allowed number of simultaneous open documents. It's not possible to set these variables to unlimited. You are restricted by the available system resources anyway.

You may define different versions for poco, libreoffice core and libreoffice online. The following software package combinations are tested and known to work, at least on Ubuntu:

Package version
poco 1.8.1
libreoffice core libreoffice-
libreoffice online libreoffice-
Package version
poco 1.8.1
libreoffice core cp-5.3-43
libreoffice online 3.1-final
Package version
poco 1.9.0
libreoffice core cp-5.3-58
libreoffice online cd-3.4.0-final
Package version
poco 1.9.0
libreoffice core cp-6.0-29-20200120
libreoffice online cp-4.0.10-1
Package version
poco 1.9.0
libreoffice core cp-6.2-4
libreoffice online cp-4.2.0-4

It's recommended to leave LOOL_PREFIX as "/opt/lool" and POCO_PREFIX empty.


As mentioned above, you need a minimal or standard installation of a supported distribution. Transfer the build-lool tar archive your build system. Unpack the archive to a suitable location, ~/tools/ for example. Adjust the configuration to your needs as described above. Start the shell script as ordinary user, building as user root does not work. The script acts as follows:

  • Appends a line to .bashrc to startup the script at login.
  • Enables the corresponding source package repositories for all enabled package repositories.
  • Updates the system software packages.
  • Installs all required software packages.
  • Reboots the system.

After login again:

  • Removes the script start command from .bashrc.
  • Gets the source packages.
  • Builds poco.
  • Builds libreoffice core.
  • Builds libreoffice online.
  • Builds installable package.

After the script has finished you find the built packages in the subdirectory "packages". There are packages for poco, libreoffice core and loolwsd. Depending on the configuration you will find poco-1.9.0.tar.xz, core-cp-5.3-58.tar.xz, loolwsd-3.4.0-final.tar.xz and a combined package lool-poco-1.9.0-core-cp-5.3-58-online-3.4.0-final.tar.xz to be installed to "/opt/lool". Since version 2.0.2 a list of required packages for the production system is generated. It's stored in the package directory for example as lool-poco-1.9.0-core-cp-5.3-58-online-3.4.0-final-required-packages.txt. The list is used by the script from the install-cloud-server script colletcion to automatically install missing packages.

If you change source versions after a first build, only the necessary components are rebuild.

The build will take some time depending on your system resources. I did some tests with a local VM and an 1&1 Cloud Server XXL. My local VM uses 4 cores of an Intel(R) Xeon(R) E5-1660 v2 CPU, 4 GByte Memory and 32 GByte disk space. The 1&1 Cloud Server XXL uses 4 CPU cores, 8 GByte memory and 160 GByte disk space.

Both, the 1&1 Cloud Server and my VM, take less than 3 hours to install all necessary software packages and to build poco, libreoffice core and libreoffice online. So, the actual cost for using the 1&1 Cloud Server XXL is about 0.20 €. The accounting for the 1&1 Cloud Server is carried out based on used minutes. Using an 1&1 Cloud Server for building libreoffice online may be advantageous especially if you have a very limited upload bandwidth.


You may install the packages manually, or use the script collection install-cloud-server, see
