+Building on OpenBSD
+-------------------
+The procedure below works on OpenBSD 5.8 with gcc version 4.8.4, cmake version 3.2.3 and Python version 2.7.10.
+
+- Install a recent gcc, python and cmake:
+
+.. code-block:: bash
+   
+   pkg_add gcc python cmake
+
+- Tell the system to actually use the recent gcc (it gets installed as egcc on OpenBSD): 
+
+.. code-block:: bash
+   
+   export CC=egcc CXX=eg++
+
+- Now procede as described for Ubuntu/Debian:
+
+.. code-block:: bash
+
+   cd open62541
+   mkdir build
+   cd build
+   cmake ..
+   make
+
