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
- libuuid: 2.17.2
- Mongo Driver: legacy-1.0.7 (from source)
- rapidjson: 1.0.2 (from source)
- gtest (only for
make unit_testbuilding target): 1.5 (from sources)
- gmock (only for
make unit_testbuilding 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 http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F):
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 libuuid-devel
Install the Mongo Driver from source:
wget https://github.com/mongodb/mongo-cxx-driver/archive/legacy-1.0.7.tar.gz tar xfvz legacy-1.0.7.tar.gz cd mongo-cxx-driver-legacy-1.0.7 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:
wget https://github.com/miloyip/rapidjson/archive/v1.0.2.tar.gz tar xfvz v1.0.2.tar.gz sudo mv rapidjson-1.0.2/include/rapidjson/ /usr/local/include
Install libmicrohttpd from sources (the
./configurecommand below shows the recommended build configuration to get minimum library footprint, but if you are an advanced user, you can configure as you prefer)
wget http://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.48.tar.gz tar xvf libmicrohttpd-0.9.48.tar.gz cd libmicrohttpd-0.9.48 ./configure --disable-messages --disable-postprocessor --disable-dauth make 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 http://googlemock.googlecode.com/files/gmock-1.5.0.tar.bz2 but google removed that package in late August 2016 and it is no longer working.
wget https://www.fiware.org/shared-content/public/gmock-1.5.0.tar.bz2 tar xfvj gmock-1.5.0.tar.bz2 cd gmock-1.5.0 ./configure make 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 email@example.com:telefonicaid/fiware-orion.git):
sudo yum install git git clone https://github.com/telefonicaid/fiware-orion
Build the source:
cd fiware-orion make
(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
sudo make install INSTALL_DIR=/usr
Check that everything is ok, invoking the broker version message:
The Orion Context Broker comes with a suite of 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
Run valgrind tests (it takes some time, please be patient):
Prepare the environment for test harness. Basically, you have to install the accumulator-server.py 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/testEnv.sh file).
mkdir ~/bin export PATH=~/bin:$PATH make install_scripts INSTALL_DIR=~ . scripts/testEnv.sh
Run test harness (it takes some time, arm yourself with patience).
make functional_test INSTALL_DIR=~
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 http://downloads.sourceforge.net/ltp/lcov-1.10-1.noarch.rpm
Do first a successful pass for unit_test and functional_test, to check that everything is ok (see above)
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
The generated RPMs are placed in directory
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!
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 https://bugs.launchpad.net/ubuntu/+source/lcov/+bug/1163758). Install lcov 1.10 from sources.
