1) Install the required libraries:

  Ubuntu 16.04

   $ sudo apt install build-essential libldap2-dev libpython3.5-dev python3-numpy

  Fedora 26
   
   $ sudo dnf install git make gcc-c++ openldap-devel python3-devel python3-numpy

2) Get the source-code and setup the environment

   $ mkdir -p $(HOME)/foo/doocs
   $ cd $(HOME)/foo/doocs
   $ git clone http://doocs-git.desy.de/cgit/doocs/Ubuntu-16.04-x86_64.git
   $ git clone http://doocs-git.desy.de/cgit/doocs/library/common/clientlib.git library/common/clientlib
   $ git clone http://doocs-git.desy.de/cgit/doocs/library/python/pydoocs.git library/python/pydoocs
   $ export DOOCSARCH=Ubuntu-16.04-x86_64

3) Compile the clientlib

   $ cd library/common/clientlib

* If you don't need EPICS support inside the DOOCS libraries, disable building libTTFapi.

   $ edit Makefile

And look for the line starting with ALLLIBS and remove the libTTFapi entries.
See the patch below:

    diff --git a/Makefile b/Makefile
    index 2c009e6..b84a360 100644

    +++ b/Makefile

   $ make -j localinstall 

4) Compile pydoocs

   $ cd ../../python/pydoocs
   $ edit Makefile
   
   a) Replace all -lTTFapi with -lDOOCSapi
   b) Than adopt the search path for python includes and libraries
      (use pkg-config --list-all | grep python to find the right name)
