Building from sources

Orion Context Broker reference distribution is CentOS 6.x. This doesn't mean that the broker cannot be built in other distributions (actually, it can). This section also includes indications on how to build in other distributions, just in the case it may help people that don't use CentOS. However, note that the only "officially supported" procedure is the one for CentOS 6.x; the others are provided "as is" and can get obsolete from time to time.

CentOS 6.x. (officially supported)

The Orion Context Broker uses the following libraries as build dependencies:

  • boost: 1.41 (the one that comes in EPEL6 repository)
  • libmicrohttpd: 0.9.48 (from source)
  • libcurl: 7.19.7
  • openssl: 1.0.1e
  • libuuid: 2.17.2
  • Mongo Driver: legacy-1.1.2 (from source)
  • rapidjson: 1.0.2 (from source)
  • gtest (only for make unit_test building target): 1.5 (from sources)
  • gmock (only for make unit_test building target): 1.5 (from sources)

We assume that EPEL6 repository is configured in yum, given that many RPM packages are installed from there (check the procedure at

The basic procedure is as follows (assuming you don't run commands as root, we use sudo for those commands that require root privilege):

  • Install the needed building tools (compiler, etc.).

    sudo yum install make cmake gcc-c++ scons
  • Install the required libraries (except what needs to be taken from source, described in following steps).

    sudo yum install boost-devel libcurl-devel gnutls-devel libgcrypt-devel openssl-devel libuuid-devel
  • Install the Mongo Driver from source:

    tar xfvz legacy-1.1.2.tar.gz
    cd mongo-cxx-driver-legacy-1.1.2
    scons                                         # The build/linux2/normal/libmongoclient.a library is generated as outcome
    sudo scons install --prefix=/usr/local        # This puts .h files in /usr/local/include/mongo and libmongoclient.a in /usr/local/lib
  • Install rapidjson from sources:

    tar xfvz v1.0.2.tar.gz
    sudo mv rapidjson-1.0.2/include/rapidjson/ /usr/local/include
  • Install libmicrohttpd from sources (the ./configure command below shows the recommended build configuration to get minimum library footprint, but if you are an advanced user, you can configure as you prefer)

    tar xvf libmicrohttpd-0.9.48.tar.gz
    cd libmicrohttpd-0.9.48
    ./configure --disable-messages --disable-postprocessor --disable-dauth
    sudo make install  # installation puts .h files in /usr/local/include and library in /usr/local/lib
    sudo ldconfig      # just in case... it doesn't hurt :)
  • Install Google Test/Mock from sources (there are RPM pacakges for this, but they don't seem to be working with the current CMakeLists.txt configuration). Previously the URL was but google removed that package in late August 2016 and it is no longer working.

    tar xfvj gmock-1.5.0.tar.bz2
    cd gmock-1.5.0
    sudo make install  # installation puts .h files in /usr/local/include and library in /usr/local/lib
    sudo ldconfig      # just in case... it doesn't hurt :)
  • Get the code (alternatively you can download it using a zipped version or a different URL pattern, e.g git clone

    sudo yum install git
    git clone
  • Build the source:

    cd fiware-orion
  • (Optional but highly recommended) run unit test. Firstly, you have to install MongoDB (as the unit tests rely on mongod running in localhost).

    sudo yum install mongodb-server
    sudo yum  update pcre            # otherwise, mongod crashes in CentOS 6.3
    sudo /etc/init.d/mongod start
    sudo /etc/init.d/mongod status   # to check that mongod is actually running
    make unit_test
  • Install the binary. You can use INSTALL_DIR to set the installation prefix path (default is /usr), thus the broker is installed in $INSTALL_DIR/bin directory.

    sudo make install INSTALL_DIR=/usr
  • Check that everything is ok, invoking the broker version message:

    contextBroker --version

The Orion Context Broker comes with a suite of functional, valgrind and end-to-end tests that you can also run, following the following procedure (optional):

  • Install the required tools:

    sudo yum install python python-flask python-jinja2 curl libxml2 nc mongodb valgrind libxslt bc
  • Prepare the environment for test harness. Basically, you have to install the script and in a path under your control, ~/bin is the recommended one. Alternatively, you can install them in a system directory such as /usr/bin but it could collide with an RPM installation, thus it is not recommended. In addition, you have to set several environment variables used by the harness script (see scripts/ file).

    mkdir ~/bin
    export PATH=~/bin:$PATH
    make install_scripts INSTALL_DIR=~
    . scripts/
  • Run test harness (it takes some time, please be patient).

    make functional_test INSTALL_DIR=~
  • Once passed all the functional tests, you can run the valgrind tests (this will take longer than the functional tests, arm yourself with a lot of patience):

    make valgrind

You can generate coverage reports for the Orion Context Broker using the following procedure (optional):

  • Install the required tools. You need lcov 1.10 - the one that comes with CentOS 6.3 (lcov 1.9) is not valid.

    sudo rpm -Uhv
  • Do first a successful pass for unit_test and functional_test, to check that everything is ok (see above)

  • Run coverage

    make coverage INSTALL_DIR=~

You can generate the RPM for the source code (optional):

  • Install the required tools

    sudo yum install rpm-build
  • Generate the RPM

    make rpm
  • The generated RPMs are placed in directory ~/rpmbuild/RPMS/x86_64.


If you have build orion in a system different from CentOS 6.x, don't hesitate to tell us and contribute to expand this section. Probably the best way if doing a pull request to modify this file with the new information. Thanks!

Debian 7

The packages are basically the same described for RedHat/CentOS above, except that we need to install packages using apt-get instead of yum.

Install Google Test and Google Mock version 1.5 directly from sources.

The version of lcov that comes with Debian 7.0 (1.9) has a bug (see Install lcov 1.10 from sources.
